Been fixing mower for people for over 5 years now and only this year did i go get specialized tools. Used the exact same method as seen here and as long as you are careful it will not hurt it no matter what anyone says.
Thanks for the video - very helpful!! A couple thoughts: thread the flywheel nut partway back on and tap on the nut. Also tie back the stopping bail so it doesn't bear on the flywheel.
Hey thanks. The tapping worked well for me. I do know that tapping on a magnet weakens it (well at least that's according to my HS physics teacher), but it gets the job done. Also, instead of clamping the flywheel to hold it in place, Stuffing a 2x4 through the grass outlet and up against the blade worked well. And check you're socket sets before you start! That nut is at least 7/8" if not 1"
@@docham HOW TO AVOID BUYING A DEEP SOCKET FOR A ONE-TIME JOB-- If your 15./16-inch socket is a standard length, for a 1/2-inch drive, simply attach a 1/2 to 3/8-inch drive adapter, and use a standard 3/8-inch drive wrench, instead. In other words, the adapter, itself, contributes enough length to avoid having to buy a 15/16 deep socket simply to clear the pull-off cup.
Nice job. I've always used a pry bar with slight pressure from underneath while tapping the top. Just have to careful where you pry up from, as to not put pressure on an easily breakable part of the engine.
The method works well. I use it all the time. Like anything else, you have to be careful to prevent causing damage. Thanks For watching! Be sure to rate Thumbs Up and share.

I take a 4x4 block of wood put it under the blade and pull the spark plug wire off and take a half inch breaker bar or a regular 3/8 ratchet and then I loosen the bolt.

I have a Toro Personal Pace mower. It was a gift or I would have never gotten it. Toro decided they needed to create a mower that uses a PTO with a belt to turn the blade. This means blocking the blade won’t stop the shaft from turning. They also made the fan blade section out of plastic. I was a bit nervous about even clamping the Vise Grips on it due to the plastic bit, but I soaked the nut with PB Blaster and let it sit for a while, clamped it and gave it a crank with my breaker bar. It came loose like butter! I wouldn’t want to clamp down on that plastic too often so I need to make certain I get all the repairs done in one removal. Thanks for the video!
This video encouraged me to get off my butt and work on an old lawnmower I bought with the intention of fixing up and selling. I was pretty much stumped when it came to removing the flywheel, and I didn't really want to buy a tool, and it would be discouraging to have to wait more time to work on it. So I used the penetrating oil tip, hit lightly on the end of the crank, and pryed up on the flywheel. It took a bit, but it did move and came off!

electronicsNmore very true but if anyone is like me, they want it off fast and think "if a little is ok then a little more is better" I learned the hard way
@@electronicsNmore I screwed up the crankshaft on a mower by accidentally striking it an angle and it rolled over the threads nut was very hard to put back on. still worked though. even with the nut on halfway its still actully possible to strip the threads if you hit it to hard and I also have done that to a mower as well. Just be carefull how you do this. You can avoid damage to your mower by buying the proper tool to remove the flywheel. this worked for me and i learned my lesson about hitting it to hard! great video
@@electronicsNmore Worked for me, thanks. By the way Tecumseh actually sells a flywheel knocker puller nut to screw on the shaft to prevent damage.

TIPS NOT MENTIONED IN VIDEO: Apply some penetrating oil on top of the flywheel around the shaft to help loosen it up before doing what's shown in this video. Use a curved or straight jaw Vise Grip, and DO NOT hit the end of the shaft too hard or you'll mushroom the end! Light taps ONLY!
Well done video. Mahalo for sharing. I tried this method today for the first time and it works like a charm. I will use it again and again until I got some specialized tools which is no longer a priority. I just had to remove a lot of parts to make room for the hammer but not big deal since I am planning a full restoration on my lawnmower. Again Mahalo (thank).
Glad it worked well for you. There is little if any reason for anyone to damage the flywheel if the procedure is done correctly. Light to moderate tapping is all it takes. Be sure to rate Thumbs Up and share with others. Thank You!

I use a block of wood under the deck to block the blade from moving. And I put back the bolt so that it is flush with the top of the shaft. And use a pry bar to pull up in the flywheel. Good to see there is other ways to do this.
Always "alternate" ways of doing things. Thanks for watching!

Be patient and use WD40 or something to help loosen the flywheel. After a bit of tap tap tapping with no apparent progress I went to the hardware store to see if they had puller, but they were closed. When I got back I tried some more and it popped loose after a little bit more effort.
Nice idea on the Vise Grips. I'll have to try that sometime when I don't have the Harbor Freight Electric Impact available (which is a VERY good $39 investment for just such a purpose.) That is a rare boxed end wrench to have that much angle. I'm guessing most people would use 3/8"- or 1/2"-drive ratchet and socket. Regarding flywheel extraction: I would endorse this methodology. He didn't hit anything hard enough to damage it. More stubborn extraction may force the use of pry bars or pullers. Protect those threads, perhaps add the nut to it. Don't pry hard enough to break the aluminum flywheel. Thanks for sharing your ideas here.

I've always screwed the nut on the shaft and using a large screw driver to put up pressure on the flywheel, I hit the shaft and the flywheel pops right off every time without damaging anything. That's how I roll!
First off thanks for sharing, not a bad idea at all for not having any “SST” tools. I like to use 11” Vice grips and a 4’ long prybar myself, that way there’s no tapping or hitting involved . PRO TIP: clean you’re treads with a wizz wheel/wire brush before removing the nut because we all know the best thread locker is rust, thanks again for you’re time.

This is the slowest method / Remove coil,file shaft , heat with propane torch spraying with blast corrosion rust and heat.2x2eight inches (wood) hammer flywheel and spray and heat 3 minutes tops .good video thanks
After you remove the flywheel nut, apply some penetrating oil between the crankshaft threads and flywheel, let soak for 1 hour, then do as I show in the video.
I’ve removed several with a pair of channel locks around the cup portion and a socket/breaker bar. Another way is to jam something between blade and deck. I do love my 3 speed 1/4” Dewalt impact better 😊.

I use 2 large screwdrivers to hold the flywheel and output shaft to its highest position, start the nut back on the crank, then one sharp blow removes it. No need to hammer on the flywheel. You could see in this video when he taps up on the flywheel the amount of end play on the output shaft. That tiny bit gives you the ability to tap down on the output shaft to release the flywheel. You can do the same thing with the screwdrivers but use an air hammer instead.
Deucealive75, Correct! Because the flywheel is NOT in contact with the upper crankcase bearing, tapping the shaft down without lifting the flywheel up to the top of the shaft end play does NOTHING but impact the lower crankshaft main bearing! Any mechanic watching this video cringes at the lack of experience proudly showing others the WRONG way to remove engine flywheels. This video is a dangerous, embarrasing joke. Take it down!
success brother now need to order the key (shredded). thank for your video 👍👍 👍... the guy that was going to repair it was charging me 70.00$!!! thanks too youuuuuu 5.00 bucks. THANK YOU AGAIN
Vise grip is a special tool for me which I do not have. Some people use rope to lock the piston. I wonder if it is safe to use neylone rope in 4 cycle engine? People saying you can damage valves. I have a feeling it should be safe to put a rope in the middle of compression cycle as the both valves will be closed. Am I right?
That was great. I have never opened a lawnmower so to be able to work on it with minimal or no special tools came in handy. I have to replace the key on mine and have to do it soon. The grass is growing fast with all the rain we have and getting expensive to pay someone for something I can do.Thanks. Ps. where I can buy a key ?
Thanks! Be sure to share with others and rate a thumbs up. You can find a key at any small engine repair shop. I would suggest buying it online. All you need is the engine model #.
Helpful video, thanks. Unfortunately, my flywheel wouldn't budge. Even tried using a three-leg gear puller, but that didn't work either. I was considering buying the genuine B&S flywheel puller tool, but there doesn't appear to be any thread in either of the designated fixing holes. M5 bolt is too large, and M4 is too small. I can't see how the puller will work without threaded holes. Are the threads an irregular size, or am I missing something else? Perhaps the thread is deeper down, and isn't metric? Please help.
@@electronicsNmore Thanks, but I don't have one. I'm more interested at this stage to know more about the typical thread specifications of the B&S flywheel. If I'm going to have to buy something for the next process, I'd rather have the right tool for the job and get it done, versus something that may or may not work.
Found out the B&S puller kit has self taping bolts. As the flywheel key seems to be fine and there's no play in it, I'm just going to leave it alone. No point in spending more money on tools. If the key ever breaks, I imagine there will be enough play between the flywheel and shaft to allow removal by the hammer and pry bar method.
1st: to lock up the flywheel pull the spark plug and insert nylon rope (pull string rope) as much as you can fit. This will stop the piston without causing damage. 2nd: pulling the flywheel without a puller. Put the bolt or nut back on the crank. Apply pressure with a crow bar under the flywheel as close to center as possible then with one swift swing of a heavy hammer to the top of the crank straight down in combination with the pressure from below the vibration will free the flywheel
Hi. I have an old kirby tecumseh 2 stoke motor and I have LITERALLY tried everything there is to get the flywheel off, from heat, to soaking the shaft in brake fluid and I've even tried heat, and the puller and hammering at the same time, but nothing has worked. Do you have anything else to suggest? Thanks.
a good method I have used in the past on riding tractors I would imagine be the same for push mower take your spark plug out put a cloth rope inside the jug that will actually stop your Pistons from moving it works very well
Use Clothesline in the spark plug hole to lock the engine. Put a block of wood on top of the crank and hit the wood with a hammer. Pry up on the flywheel under the thick part while hammering on the wood. It'll pop up! A knock-off tool works also. Set magneto gap with a paper calling card.
As a precaution against damaging the flywheel, would it make sense to put a block of wood between the hammer and the bottom of the flywheel, so that you'd be hitting the block instead of the flywheel, and so that the striking would distributed over a broader area?

You didn't claim this is the best method, just that it does work when the instructions are followed so you don't deserve the unfair and worthless comments such as the self proclaimed mechanic that demanded it be taken down. I was very surprised to learn mild hammer taps didn't fail to pop it or cause harm by hitting the edge of the flywheel. I appreciate you sharing this interesting and valuable knowledge even though I wouldn't choose this method.
There's a time and place for everything. If you didn't have any specialized tools on hand, you'd do it. Hammer blows weren't that hard. :-) Thanks for watching!
Would I be able to do this on a Tecumseh engine that’s mounted on the top of the snow blower but the flywheel is in the back facing out? Any ideas? Thanks!
Pull/ Clamp the Safety Shutoff lever and it will release the pressure the flywheel "Brake" from the fly wheel. Go to 4:30 and it is the "brake" in front of the spring at the bottom of the video.
My flywheel isn’t spinning and the way around would u know what is wrong Will it be valves or my piston rod bc I don’t wanna take the hole block apart.
Take the spark plug out of the hole and look inside with a flashlight to see if the piston moves up and down as you rotate the engine. If it doesn't then the connecting rod broke. Also make sure the blade isn't jammed up and the flywheel brake isn't engaged.
An improvement to this would be to use the claw of a second hammer to pull UP on the flywheel while tapping the end of the crank. It literally makes it come off in 1-3 hits without EVER striking the flywheel at all
What if the key is sheared (the whole reason I'm in there)? Seems pretty tight. Any good tricks for that. I've sheared two in the last two seasons. Last year, a neighbor got it off for me, but didn't tell me what he did.
+electronicsNmore Thanks, I don't have a problem getting the top nut off, it's with rapping on the flywheel to pop it off. I don't want to whack too hard and crack the flywheel.
jonathan lucier I guess you didn't understand what he was trying to say at the beginning of the video he said he's going to show you how to do it if you don't have any special tools that includes a battery operated tool Jonathan stay with us here he didn't say I'm going to do it is and then everybody else give me their opinion how to do it better wrong videoyou could've just said you did a hell of a job guy getting that off and I think he would appreciate it have a great day
Good video! I Liked and Subbed! I have a Tecumseh 10hp engine and I couldn't take the flywheel off so now I'll try this btw the engine is for my go kart I'm restoring.

How many times do you have to follow this procedure's steps before I can expect the fly wheel to come loose? Or how much time should I spend trying to make it work? I've been trying to remove the flywheel from my mower's engine for about a day with this method and it's not even close to coming off! Anybody got any ideas for me?
my engine has an aluminum flywheel. the puller put some stress cracks in it. I used a 3/4 box wrench like a ball joint chisel. If you have an old box end wrench, you can grind it down to a two prong wedge like a ball joint chisel. check the shaft behind the flywheel, to what thickness you need.
Glad you enjoyed the video Adrian! I have a lot of excellent videos on my channel that cover many different subjects, so be sure to check out my extensive video playlists for other videos of interest to you, rate thumbs up, and SHARE my channel with others. Thank You
Just use a block of wood and block off the blade from underneath instead of taking chance of screwing up flywheel, coil or anything else if the vise grips slip. If the blade is off you can use a pipe wrench to grasp the driveshaft underneath.
just remove spark plug and stuff some rope inside cylinder to unscrew that bolt. These flywheels crack so easily. To remove flywheel I used two crowbars to lift it.
Take center nut off, then take your hammer and smack the center bolt on top a couple times. If that doesn't pop it off, then put a screw driver up under the flywheel to put upward pressure on the flywheel, then take your hammer and smack that center bolt again! Works with any mower!
If you hit the crankshaft too hard, you'll mushroom the threads, so it's better to leave the nut on to protect the threads from damage. Thanks for watching!
The hammer works fine just as long as it is done carefully. You need the shock from the hammer to loosen up the flywheel. The mallet absorbs shock, so I doubt the results will be as good. Thanks for watching! Be sure to share my channel, and rate thumbs up.
Take your time and keep tapping. Try penetrating oil on the spindle/flywheel. Worst case, apply heat to the spindle/threads. Do not get carried away, otherwise you can melt the top seal on the crankshaft. The seal is easy to replace if you did burn it.
I have entered my info. for what I need,(Briggs and Stratton 700 series, 190 cc, key start and self propelled), but I can't find what I'm looking for only videos that are close to what I'm searching for. I thought you can find ANYTHING on the Web. I guess I keep poking the wrong spider or something!?!?! I guess with watching about 4 videos I can, Prayerfully, fix my lawn mower mower!!!
haha used a puller on mine today as I needed to replace the pin and the whole dam thing shattered! looks like I will have to look to see if I can get a new one :(
If you used the specially designed puller, that should not have happened. You must of used a 2 or 3 jaw puller and applied too much force and did not tap all around the flywheel. You can find a used one at a lawn mower repair shop.
yup was a 2 jaw puller...all I had at the time. ironic thing was I turned around to get a hammer to tap it and it was at that point it went BANG and when I looked back it was in two halves :s....bad luck I guess
You could have applied a little heat to the flywheel right around the crankshaft using a propane torch while the 2 jaw puller was applied. That would have expanded the metal and allowed it to pop off. Just don't apply too much heat!
Some people may not live near an auto parts store, like me. :-) If they don't, or do not want to spend money on a puller, this method works just fine. Thanks

My Briggs had a 15/16" nut. Be sure you buy a deep socket.
@@docham HOW TO AVOID BUYING A DEEP SOCKET FOR A ONE-TIME JOB--
If your 15./16-inch socket is a standard length, for a 1/2-inch drive, simply attach a 1/2 to 3/8-inch drive adapter, and use a standard 3/8-inch drive wrench, instead. In other words, the adapter, itself, contributes enough length to avoid having to buy a 15/16 deep socket simply to clear the pull-off cup.
Some are 3/4, depends on engine and therefore crank size
My briggs engine has 3 bolts on the blade bar & the large centre bolt came off with a 15 mm socket as it the same size as the imperial equivelent .
Nice job. I've always used a pry bar with slight pressure from underneath while tapping the top. Just have to careful where you pry up from, as to not put pressure on an easily breakable part of the engine.
When you have to go without, you improvise. This does work. A heavy hand will cause more damage than an alternate procedure. Good video.

If you are careful, you will not cause any damage to the engine or flywheel, and the flywheel will come right off. I have done it many times before.
Thanks For Watching! Be sure to rate Thumbs Up and Share.
Thank you. I couldn't find out how to take it off before I found your video, no other techniques worked!!
As long as you do it carefully, it shouldn't break. I have many excellent videos on my channel, so be sure to look over my extensive video playlists for other videos of interest to you, rate thumbs up, and share. Thanks for watching!
TIPS NOT MENTIONED IN VIDEO: Apply some penetrating oil on top of the flywheel around the shaft to help loosen it up before doing what's shown in this video. Use a curved or straight jaw Vise Grip, and DO NOT hit the end of the shaft too hard or you'll mushroom the end! Light taps ONLY!
Great job
David Ramos Glad you enjoyed it. Be sure to check out my video playlists and share. Thanks!
electronicsNmore what tool
how do I get the pisten off what tool do I need
a little bit of panther piss really helped get that sucker off
Hi there Just checking with you for flywheels puller can fit all Lawnmower type
Good teaching methods. I like the way you use a little repetition a lot of demonstration and talk while doing the demo.
Thank you! I only post videos with methods proven to work.
You just saved my ass, thank you so much for this video man. Just repaired my lawnmower because of you.
Glad to hear that. :-) Be sure to rate thumbs up, share my channel with others, and check out my other videos as well. Thank you!
Great video, you made everything look easy. I didn’t notice, but did you remove the flywheel key before doing all that?
Well done video. Mahalo for sharing. I tried this method today for the first time and it works like a charm. I will use it again and again until I got some specialized tools which is no longer a priority. I just had to remove a lot of parts to make room for the hammer but not big deal since I am planning a full restoration on my lawnmower. Again Mahalo (thank).
Glad it worked well for you. There is little if any reason for anyone to damage the flywheel if the procedure is done correctly. Light to moderate tapping is all it takes. Be sure to rate Thumbs Up and share with others. Thank You!
Thank fucking god finally a video with the tools I have and not the special tools every other video uses or the dangerous methods that will probably break your flywheel
Just do it carefully, and it should work for you. Thanks for watching!
I did just as you said and it popped like magic. thank you so much!
Great to hear Shawn! Be sure to check out my wide range of videos for many other videos of interest to you, rate thumbs up, consider subscribing, and share links to my videos. Thank you!
I use a block of wood under the deck to block the blade from moving. And I put back the bolt so that it is flush with the top of the shaft. And use a pry bar to pull up in the flywheel.
Good to see there is other ways to do this.
Always "alternate" ways of doing things. Thanks for watching! I have a lot of excellent videos on my channel that cover many different subjects, so be sure to check out my extensive video playlists for other videos of interest to you, rate thumbs up, and most importantly share my channel with others.
Be patient and use WD40 or something to help loosen the flywheel. After a bit of tap tap tapping with no apparent progress I went to the hardware store to see if they had puller, but they were closed. When I got back I tried some more and it popped loose after a little bit more effort.
A "C" clamp should also work in case you don't have vise grips.
Nice idea on the Vise Grips. I'll have to try that sometime when I don't have the Harbor Freight Electric Impact available (which is a VERY good $39 investment for just such a purpose.) That is a rare boxed end wrench to have that much angle. I'm guessing most people would use 3/8"- or 1/2"-drive ratchet and socket.
Regarding flywheel extraction: I would endorse this methodology. He didn't hit anything hard enough to damage it.
More stubborn extraction may force the use of pry bars or pullers. Protect those threads, perhaps add the nut to it. Don't pry hard enough to break the aluminum flywheel.
Thanks for sharing your ideas here.

Glad you liked it. I have many videos that saved people incredible amounts of money. Thanks for watching!
I've always screwed the nut on the shaft and using a large screw driver to put up pressure on the flywheel, I hit the shaft and the flywheel pops right off every time without damaging anything. That's how I roll!
First off thanks for sharing, not a bad idea at all for not having any “SST” tools. I like to use 11” Vice grips and a 4’ long prybar myself, that way there’s no tapping or hitting involved . PRO TIP: clean you’re treads with a wizz wheel/wire brush before removing the nut because we all know the best thread locker is rust, thanks again for you’re time.

This is the slowest method
/ Remove coil,file shaft , heat with propane torch spraying with blast corrosion rust and heat.2x2eight inches (wood) hammer flywheel and spray and heat 3 minutes tops .good video thanks
Thank you very much. Very useful video. Solved my problem.
Glad it helped
Such a simple solution! Glad I saw this afore shelling out on a puller. Thanks for posting from England
After you remove the flywheel nut, apply some penetrating oil between the crankshaft threads and flywheel, let soak for 1 hour, then do as I show in the video.
Wanted you to know this video keeps paying dividends. All your suggestions worked like clockwork. Thank you!
Glad it helped! Be sure to share my video links with others. Thank you
I’ve removed several with a pair of channel locks around the cup portion and a socket/breaker bar. Another way is to jam something between blade and deck. I do love my 3 speed 1/4” Dewalt impact better 😊.
Yes, a 2x4 jammed works great. Thanks for watching Brad! Be sure to look over my video playlists below for many other videos of interest to you, and most importantly take one minute to share a link to my channel with others on social networking sites. Thanks

This video is still helping people today. I have the same motor on my pressure washer. Hard to find parts for this specific engine.
I have many videos that will remain popular for years to come. :-) Be sure to check out my extensive video playlists, rate thumbs up, and share. Thanks!
I use 2 large screwdrivers to hold the flywheel and output shaft to its highest position, start the nut back on the crank, then one sharp blow removes it. No need to hammer on the flywheel. You could see in this video when he taps up on the flywheel the amount of end play on the output shaft. That tiny bit gives you the ability to tap down on the output shaft to release the flywheel. You can do the same thing with the screwdrivers but use an air hammer instead.
Deucealive75, Correct! Because the flywheel is NOT in contact with the upper crankcase bearing, tapping the shaft down without lifting the flywheel up to the top of the shaft end play does NOTHING but impact the lower crankshaft main bearing! Any mechanic watching this video cringes at the lack of experience proudly showing others the WRONG way to remove engine flywheels. This video is a dangerous, embarrasing joke. Take it down!
success brother now need to order the key (shredded). thank for your video 👍👍 👍... the guy that was going to repair it was charging me 70.00$!!! thanks too youuuuuu 5.00 bucks. THANK YOU AGAIN
I knew it would work. :-)
Yay
Vise grip is a special tool for me which I do not have. Some people use rope to lock the piston. I wonder if it is safe to use neylone rope in 4 cycle engine? People saying you can damage valves. I have a feeling it should be safe to put a rope in the middle of compression cycle as the both valves will be closed. Am I right?
Stone smooth - I have an impact wrench but needed help getting the wheel off
Have a gudu
That was great. I have never opened a lawnmower so to be able to work on it with minimal or no special tools came in handy. I have to replace the key on mine and
have to do it soon. The grass is growing fast with all the rain we have and getting expensive to pay someone for something I can do.Thanks.
Ps. where I can buy a key ?
Thanks! Be sure to share with others and rate a thumbs up. You can find a key at any small engine repair shop. I would suggest buying it online. All you need is the engine model #.
Helpful video, thanks. Unfortunately, my flywheel wouldn't budge. Even tried using a three-leg gear puller, but that didn't work either. I was considering buying the genuine B&S flywheel puller tool, but there doesn't appear to be any thread in either of the designated fixing holes. M5 bolt is too large, and M4 is too small. I can't see how the puller will work without threaded holes. Are the threads an irregular size, or am I missing something else? Perhaps the thread is deeper down, and isn't metric? Please help.
Try heating the flywheel with a torch around the shaft, then tap upwards.
@@electronicsNmore Thanks, but I don't have one. I'm more interested at this stage to know more about the typical thread specifications of the B&S flywheel. If I'm going to have to buy something for the next process, I'd rather have the right tool for the job and get it done, versus something that may or may not work.
Found out the B&S puller kit has self taping bolts. As the flywheel key seems to be fine and there's no play in it, I'm just going to leave it alone. No point in spending more money on tools.
If the key ever breaks, I imagine there will be enough play between the flywheel and shaft to allow removal by the hammer and pry bar method.
Dang good video thanks for all you do!!!!!
1st: to lock up the flywheel pull the spark plug and insert nylon rope (pull string rope) as much as you can fit. This will stop the piston without causing damage. 2nd: pulling the flywheel without a puller. Put the bolt or nut back on the crank. Apply pressure with a crow bar under the flywheel as close to center as possible then with one swift swing of a heavy hammer to the top of the crank straight down in combination with the pressure from below the vibration will free the flywheel
You don't need to do that, you can insert a 2x4 between the blade and mower frame if uncomfortable with my method. Thanks for watching!
A brass hammer is worth its weight in gold for these kinds of jobs.
I’ve got a two-year-old lawnmower sitting in my yard with a sheared flywheel key. This might be the fix!
Good job

Hi. I have an old kirby tecumseh 2 stoke motor and I have LITERALLY tried everything there is to get the flywheel off, from heat, to soaking the shaft in brake fluid and I've even tried heat, and the puller and hammering at the same time, but nothing has worked. Do you have anything else to suggest?
Thanks.
You may have to use the specially designed puller. :-(
Will try this soon, is it not best to put nut on level with shaft while hitting,
a good method I have used in the past on riding tractors I would imagine be the same for push mower take your spark plug out put a cloth rope inside the jug that will actually stop your Pistons from moving it works very well
Whatever works for you! :-) Thanks for watching
Thank you
You're welcome. Be sure to share the video link with others. Thank you!
I use a block of wood to block the blade to keep it from moving and use a pry bar to push up on the flywheel while taping on the shaft
That works too! Thanks for watching
Use Clothesline in the spark plug hole to lock the engine. Put a block of wood on top of the crank and hit the wood with a hammer. Pry up on the flywheel under the thick part while hammering on the wood. It'll pop up! A knock-off tool works also. Set magneto gap with a paper calling card.
You can also wedge a 2x4 between the blade and body of the mower.
@Marty Stevens.....what you describe is nothing short of back-woods, hack mechanics.
As a precaution against damaging the flywheel, would it make sense to put a block of wood between the hammer and the bottom of the flywheel, so that you'd be hitting the block instead of the flywheel, and so that the striking would distributed over a broader area?
Do whatever you feel comfortable doing. :-) Thanks for watching!
Many thanks for sharing the tip.

Another excellent video. Can we see more of the dog?
great video! Ruined my flywheel taking it off. Wish I had seen your video first. next time I will take the nut off first.
would you need a vice grip if the flywheel won't move, mine is stuck and I do not know why? Need to remove it to find out.
Probably is locked up and needs to be rebuilt which is usually not worth it on push mowers.
Brilliant thank you
Glad you liked the video Paul. It works when done properly and carefully.
You didn't claim this is the best method, just that it does work when the instructions are followed so you don't deserve the unfair and worthless comments such as the self proclaimed mechanic that demanded it be taken down. I was very surprised to learn mild hammer taps didn't fail to pop it or cause harm by hitting the edge of the flywheel. I appreciate you sharing this interesting and valuable knowledge even though I wouldn't choose this method.
There's a time and place for everything. If you didn't have any specialized tools on hand, you'd do it. Hammer blows weren't that hard. :-) Thanks for watching!
Would I be able to do this on a Tecumseh engine that’s mounted on the top of the snow blower but the flywheel is in the back facing out? Any ideas? Thanks!
Don't see why not.
I mushroomed so many flywheels, so I had to watch this video
As long as you do it as I show, and don't hit too hard, you won't mushroom the threads. :-)
Thanks for tutorial, it was a huge help!
Your welcome!
Pull/ Clamp the Safety Shutoff lever and it will release the pressure the flywheel "Brake" from the fly wheel.
Go to 4:30 and it is the "brake" in front of the spring at the bottom of the video.
My flywheel isn’t spinning and the way around would u know what is wrong Will it be valves or my piston rod bc I don’t wanna take the hole block apart.
Take the spark plug out of the hole and look inside with a flashlight to see if the piston moves up and down as you rotate the engine. If it doesn't then the connecting rod broke. Also make sure the blade isn't jammed up and the flywheel brake isn't engaged.
An improvement to this would be to use the claw of a second hammer to pull UP on the flywheel while tapping the end of the crank. It literally makes it come off in 1-3 hits without EVER striking the flywheel at all
Some are really stuck on the crankshaft, so it may not work. Thanks for watching!
What if the key is sheared (the whole reason I'm in there)? Seems pretty tight. Any good tricks for that. I've sheared two in the last two seasons. Last year, a neighbor got it off for me, but didn't tell me what he did.
If the shaft turns, then keep the blade from turning using a 2x4
+electronicsNmore Thanks, I don't have a problem getting the top nut off, it's with rapping on the flywheel to pop it off. I don't want to whack too hard and crack the flywheel.
Apply penetrating oil around the entire shaft and allow to sit. You need to keep tapping if you do not have a puller.
+electronicsNmore I sprayed it, waited a while, came back in a couple hours, and rapped gently it with a rubber mallet and it slid right off. Thanks.

Great! Be sure to rate thumbs up and share
I use a battery operated rachet 1/2. dont need vise grips. make sure your going in the direction of removing the nut or you will rip it off.
jonathan lucier I guess you didn't understand what he was trying to say at the beginning of the video he said he's going to show you how to do it if you don't have any special tools that includes a battery operated tool Jonathan stay with us here he didn't say I'm going to do it is and then everybody else give me their opinion how to do it better wrong videoyou could've just said you did a hell of a job guy getting that off and I think he would appreciate it have a great day
Good video! I Liked and Subbed! I have a Tecumseh 10hp engine and I couldn't take the flywheel off so now I'll try this btw the engine is for my go kart I'm restoring.

how about a 3/4 inch box wrench underneath the flywheel like a ball joint removal tool?
You won't be able to fit it.
Thanks for the video
Thanks for watching Chris. Be sure to share and rate Thumbs Up.
How many times do you have to follow this procedure's steps before I can expect the fly wheel to come loose? Or how much time should I spend trying to make it work? I've been trying to remove the flywheel from my mower's engine for about a day with this method and it's not even close to coming off! Anybody got any ideas for me?
j ramirez yea, use a puller!
my engine has an aluminum flywheel. the puller put some stress cracks in it. I used a 3/4 box wrench like a ball joint chisel. If you have an old box end wrench, you can grind it down to a two prong wedge like a ball joint chisel. check the shaft behind the flywheel, to what thickness you need.
awesome video thanks.....
Glad you enjoyed the video Adrian! I have a lot of excellent videos on my channel that cover many different subjects, so be sure to check out my extensive video playlists for other videos of interest to you, rate thumbs up, and SHARE my channel with others. Thank You
Just use a block of wood and block off the blade from underneath instead of taking chance of screwing up flywheel, coil or anything else if the vise grips slip. If the blade is off you can use a pipe wrench to grasp the driveshaft underneath.
That works too. :-) Thanks for watching!
Thank you sir good vedio
You're welcome Mark!
Does anyone know what size nut that is on the flywheel? Or should I say what size socket does it take to remove it?
24 mill
thanks brother!
+Joe Cline You're welcome!
just remove spark plug and stuff some rope inside cylinder to unscrew that bolt. These flywheels crack so easily. To remove flywheel I used two crowbars to lift it.
Take center nut off, then take your hammer and smack the center bolt on top a couple times. If that doesn't pop it off, then put a screw driver up under the flywheel to put upward pressure on the flywheel, then take your hammer and smack that center bolt again! Works with any mower!
If you hit the crankshaft too hard, you'll mushroom the threads, so it's better to leave the nut on to protect the threads from damage. Thanks for watching!
I've tried about a half dozen coils and I can't get one to fit what motor do you suggest taking one from
Shouldn't be that hard to find a replacement locally or online. Thanks for watching
I would put the nut on that spindle shaft. so I don't damage the threads. also apply penetration oil. even heat the area aound it abit.
I wasn't hitting the end hard enough to cause any damage. Leaving the nut on, is a good idea.
thanks

Need view on 26 hp brigs flywheel removal
I wonder if a rubber mallot would work just as good?
The hammer works fine just as long as it is done carefully. You need the shock from the hammer to loosen up the flywheel. The mallet absorbs shock, so I doubt the results will be as good.
Thanks for watching! Be sure to share my channel, and rate thumbs up.
Take your time and keep tapping. Try penetrating oil on the spindle/flywheel. Worst case, apply heat to the spindle/threads. Do not get carried away, otherwise you can melt the top seal on the crankshaft. The seal is easy to replace if you did burn it.
I have entered my info. for what I need,(Briggs and Stratton 700 series, 190 cc, key start and self propelled), but I can't find what I'm looking for only videos that are close to what I'm searching for.
I thought you can find ANYTHING on the Web. I guess I keep poking the wrong spider or something!?!?! I guess with watching about 4 videos I can, Prayerfully, fix my lawn mower mower!!!
haha used a puller on mine today as I needed to replace the pin and the whole dam thing shattered!
looks like I will have to look to see if I can get a new one :(
If you used the specially designed puller, that should not have happened. You must of used a 2 or 3 jaw puller and applied too much force and did not tap all around the flywheel. You can find a used one at a lawn mower repair shop.
yup was a 2 jaw puller...all I had at the time.
ironic thing was I turned around to get a hammer to tap it and it was at that point it went BANG and when I looked back it was in two halves :s....bad luck I guess
You could have applied a little heat to the flywheel right around the crankshaft using a propane torch while the 2 jaw puller was applied. That would have expanded the metal and allowed it to pop off. Just don't apply too much heat!
electronicsNmore
Or you can go rent one from an auto parts store.
Some people may not live near an auto parts store, like me. :-) If they don't, or do not want to spend money on a puller, this method works just fine.
Thanks
thank you...
So i have acces to an impact wrench but mines does not hVe a bolt
