Awesome tip that really works! Spent about 3 hours today fruitlessly trying to figure out how to remove a Briggs and Stratton engine from its induction generator rotor. Tried your tip and all done in just 15 minutes and no damage, thank you so much, your a star!
You are the first person to get right to it and be very clear about what i was looking for on this ,i fix alot of thing's and i have wasted a lot of time look on this thing and come up with nothing. So thank you so very much I'm Terry in Topeka KS
I have been trying to get the generator of my Honda for a while, saw this video in the morning, used your trick and its now off. Brilliant :) Thank you Dan
Hadn't thought to thread the end of the shaft. Great idea! SAved me from buying 'another' puller to add to my collection and possibly ruin something in the process. THANKS!
I just loosen up the long bolt, then slam the end of the generator onto a big wood block. It has worked for me so far, but each generator design is different. Good puller idea, I will definately keep it in mind!!!
thank you so much for the video I bought a old homelite generator that was locked up and your trick worked great I used a long drill bit and it pop off thanks a million I almost really mess up.
Thanks man, I need to change the engine oil seal on a Vanguard 7.5 Briggs and Stratton Pro 4000 portable genset. I've been struggling with this exact dilemma and you've shown me what I need to do to remove that armature. Thanks donyboy.
Tried your method the other day and worked perfectly. Thanks for the great instructional vid. One thing I changed is I used A hardened rod (to lessen the chance of it mushrooming and getting stuck) and used A impact wrench instead of roping the cylinder.
One could dry putting lube into hole and grease nipple. If its tight enough grease pressure should be enough to pop it out with out danger of mushrooming rod, though bit messy and bit grease gets wasted there, though if there is connection hole outside it will leak from there if its not extremely stiff grease. How much force grease system has is telling from guys who have managed to crack cast iron parts when there has not been way for grease to exit and that some tracked vehicles use grease in cylinder to tension the tracks.
Great video. Same technique is used on Polaris ATV to remove the primary clutch from the engine, but polaris already has the threads in the clutch for the large screw in bolt. I have removed the bad armature from my older Generac L4001, I only wish I could come up with a sutiable replacement on this apparent no longer available replacement part. Complete engine awaiting repair if I ever manage to find an armature. Thanks again for the clear, concise video.
Thanks for the assistance. I ended up using the two prybar and hammer method, but I wouldn't have figured it out that the shaft was tapered without your help. If the taper hadn't released, I was on my way to the tap and die set!
A friend sent me this video as I was having trouble removing the armature on my Lifan generator after the rod on the 190FD engine failed. I has resorted to banging on the armature with no success. Luckily the shaft had threads and after trial & error I got the armature off using my DeWalt impact wrench. Great video, thanks!! Andy
Thank you so much! I have a Winco 4PTH - 3M/L10 it said to use a hammer. No-go, but a 3/8" x 24 tap fit PERFECT. Got a grade 8 3/8 x 24 and cut a gutter nail head and end off - WHAM! There it is! Now I can replace the governor :)
Great tip on the puller. I wouldn't have known that the armature was on a taper. Is there usually a shaft key involved or just the bare taper? If it is the taper alone that is transmitting the power to the rotor shaft, then I would be a bit leery of putting any lubricant other than light machine oil to prevent corrosion. The taper is meant to lock together. I just watched your promo video. I think that you have one of the most clean and professional looking channels I have seen. I am now subscribed.
Cool, I learned something new! How can you tell if an electric motor is bad or if an armature is bad. Can a RUclipsr rewind a motor or you need a special machine for that? Thanks for making the videos!
I am a generac master tech per factory spec the recommended way to remove the armature is striking with a rubber mallet rotating and repeating until it comes loose
love this channel, and others like Taryl and Mustie1 , with North America going crazy buying generators , the more generator videos you do the more views ... i guess we all want to know how to keep them running for as long as possible .... a push mower not so much but they are getting way more expensive than say 5 yrs ago .... thanks to you guys a dirty carb on my champion is no longer something i worry about , i do wish somebody would tear down and cross reference carbs and other parts on the newer line of Chinese Inverter suitcase generators , about 3-4 different lines of the same generators, Buffalo tools that sells the Sportsman line told me they will be stocking parts in the future, they at least have parts lists and schematics. the line I bought doesnt at all ...... Thanks for doing these videos
Donny, Very well done, thank you for sharing. I just finished using your technique, including tapping the center of the armature. If you ever find yourself in MA/RI there is some cold beer or hot coffee waiting for you. Subscribed.
Hi Guys First, thread the inside end of your rotor tube with the appropriate size tap and find a suitable bolt with a good amount of thread. Stand the Generator vertically with the rotor at the top. Wrap a good amount of pipe tape on all the threads of the bolt you found. Fill the rotor shaft hole with water. Start the bolt into the end of the rotor shaft and using your favorite electric impact tool, run the bolt in fairly quickly and the hydraulic pressure will pop the rotor off the end of the crankshaft. Works every time. If its leaking around the threads allot, put more pipe tape on your bolt. Cheers Willy
Just found your channel. Wanted to say thanks for this great tip. Worked for me just like you described. My armature didn't quite do the same thing as yours but the result was the same. I tightened the bolt but dropped the wrench I was using and when I went to pick the wrench up the armature popped from just having some pressure on it. Ordering a new engine this week. Again THANKS for the informative videos. Take Care...
@BriggsMower what i do is solder them together, or get a new 5mm pice of wire and solder it to the old wire, then cover it with heat shrink, like 2 to 3 layers
Dang. I wish I'd seen this last week. I tried everything I could think of, prying, pullers, mallet. I ended up buying a harbor freight tap n die set and doing the same exact thing (except no rope in the cylinder). As stuck as it seemed, I kinda thought it would just strip the threads right out, but it worked exactly like yours, popped right off and fell on the bench.
I just pulled apart a Companion 5250 (same as many of the Devillbis/ Porter Cable units). The bolt ended up snapping off when trying to tighten it up on the end of the rotor, but I hit the rotor with a hammer, and that in combination with the broken bolt putting pressure inside did the trick anyway. Luckily, this rotor and stator were completely burned up, so I was only saving the engine!
the older homelite i bought off craigslist for 35.00 dollars has a briggs 1970's on it wasn't locked up after pulling the gen and getting into it it had never been ran and it had some kind of stop on it I guess for shipping it . have you ever come across anything like that. it was around the shafted I could have just cut it but your trick worked great. model e4000-1 are these good gen and the carb was bone dry never had gas in it.
Hello, I'm very curious. Does that rotor have a permanent magnet. If there is no magnet, where is DC current given to the rings on the rotor. Greetings. I am from Turkey. Do you know Turkey.
This worked like a charm, thanks!. Btw, I have a Coleman PM0435005 and the fan (0063406) seems to have ripped itself to shreds. I cannot for life of me find a replacement. If I just remove the fan would strapping a box fan to the chassis dissipate the heat enough to make this a usable product again or am I screwed? Are there any work-arounds, 3d printed parts, aftermarket, etc??
When refitting the armature, what do you torque the bolt up to, can't find any info on this? Want it to be tight enough but not overtight and strip the thread.
good day sir i got a brushless generator on repair .. the problem is the varistor on the diodes are broken and i got an open diode on it, its located on the armature ... my problem is i forgot how will i put back the diodes was there any polarity on diodes ...do i have to reverse the second diode on the second pole ...
I have an 8750 black max generator with bad winding's. I ordered a complete rebuild for the alternator but it came with 3 wires coming off the winding's (2 black and one white) they are not labeled. The original winding's had 4 wires. (blue red white brown) and the rotor has a the studs the wires attach to but there is no stud for L2. Did I get the wrong parts? or is there a way to deal with this. Thanks Paul

Hadn't thought to thread the end of the shaft. Great idea! SAved me from buying 'another' puller to add to my collection and possibly ruin something in the process. THANKS!
Thank you so much! Two hours of screwing around in trying to remove 'er and then I find this video.. Already threaded so 10 minutes later it's free.
I just loosen up the long bolt, then slam the end of the generator onto a big wood block. It has worked for me so far, but each generator design is different.
Good puller idea, I will definately keep it in mind!!!

Thanks for the video. After two days of trying. Ten minutes after this video, job done.
Glad it helped
THe windings were press on tighter than I expected, good job dony
Excellent video - clear and to the point.
Great video buddy appreciate it. I would have never gotten it apart without your help
No problem 👍
Thanks for the assistance.
I ended up using the two prybar and hammer method, but I wouldn't have figured it out that the shaft was tapered without your help.

Used your method it worked well. not using anti seize for reassembly . You did an excellent video. Thanks.

Thanks , I broke my Honda Gen. all the way down and didn't have a clue how to get this armature off. I do now!
Thanks this may come in handy some day. I think I would put a soft landing pad for it when it jumped off. Keep posting!
After fooling around for 3 hours with a car jack the damn thing did not budge but after I saw your video it came off in 20 minutes. Thanks
Great tip on the puller. I wouldn't have known that the armature was on a taper. Is there usually a shaft key involved or just the bare taper?

Thanks a bunch. I was just struggling with how to do it. I love free advice.
You are a true mechanic with that trick good job
Cool, I learned something new! How can you tell if an electric motor is bad or if an armature is bad. Can a RUclipsr rewind a motor or you need a special machine for that? Thanks for making the videos!
Thanks that helped! My first thought was to use a bolt and a slide hammer.
Thanks, I've been trying to covert my generator into an engine for my go kart for sometime now. Had no clue how to get the armature off. Thanks again!

Worked a treat, saved me a lot of head scratching. Thank you
Excellent idea.
I thought I needed to do this, but I was able to fix my generator with flashing the field coils.
Most of the time flashing will work.
works great. make sure to use the sizes he says in the vid, else u may break the rod if it is smaller. thanks donyboy
I am a generac master tech per factory spec the recommended way to remove the armature is striking with a rubber mallet rotating and repeating until it comes loose
truly you're the small engine doctor, keep sharing very useful ideas. thanks
thanks you
On my generator there is a bolt and i cant turn it without turning the armature.
Thanks a million........ been fighting this for a week and took 20 min after seeing your video.
WEH
very direct ,straight to the point , worked exactly ,
thanks dude, the bold pushing inside is a great idea .

thanks , 14 hp vanguard , no threads . did just the way you showed and perfect off in 5 minutes , thanks so much
Thanks! I'll be doing this soon and this is extremely useful. I have a question though. Have you ever re-wound an armature like this?
thanks to you I saved a generator. thanks for the how to
excellent advice as always from this you-tuber
thanks Tony!
Man Thanks to this video I could remove my armature of my GX200 engine so usefull this,
@BriggsMower what i do is solder them together, or get a new 5mm pice of wire and solder it to the old wire, then cover it with heat shrink, like 2 to 3 layers
Oh hey donyboy73 I guess you did have a video on how to get the engine off of the generator. Thanks for sharing.
Donyboy is the best!!! No question about it.
Awesome, have two generators I need to take apart, thanks for this video.
Dude, you rock. I was just trying to figure this out, and this video helped a lot. THANK YOU!

Thx. This video helped allot. Now I can get my project moving along. God bless.
Dony...you saved my booty...I have to do 3 of these.
+TheCaptainSlappy no prob, lol
i like your videos,this was my job for years working on motor shop
I saw this video 4hours too late ☹️😂 broke mine and it was the exact same model. Thanks for the genius tip tho!

please tell me winding Generator
i got the same one u was doing thanks u so much i was stuck for a minute
the older homelite i bought off craigslist for 35.00 dollars has a briggs 1970's on it wasn't locked up after pulling the gen and getting into it it had never been ran and it had some kind of stop on it I guess for shipping it . have you ever come across anything like that. it was around the shafted I could have just cut it but your trick worked great. model e4000-1 are these good gen and the carb was bone dry never had gas in it.
Thank you mate .. great advice .. and you have a really positive friendly manner .. I will you well.
Rory.
I can't tell my friends. they won't pay Me to fix there stuff . good job bro .
Nice demo, Dony.
Mr. Donyboy thank you very much, from Venezuela!!!!!!
+JDBD83 you're welcome
I just checked out your channel Don. You just got another subscriber. Great content.
Dony you make it look easy. Thank you!
Thanks for posting this. I used this metter yesterday.
that was great info thanks like a clutch puller on sleds
Thank you for putting this video up! Really helpful.
Hello, I'm very curious. Does that rotor have a permanent magnet. If there is no magnet, where is DC current given to the rings on the rotor. Greetings. I am from Turkey. Do you know Turkey.
muy util este video se los agradesco no encontraba como desmontar el rotor gracias
thank you very much it helped me to open my alternator.lloyd australia
Threading was easy as i had a tap but no luck snapped the bolt off inside so threads were good she just didnt want to give up
@BillyInnes thanks for watching!
thanks for watching gus
Thanks Donyboy, this was very helpful. Watched another video on chainsaw carb clean up few months back. thanks for your videos.
have a nice day
i did this and it worked!
You saved the day. Worked like a charm!

very useful and brilliant ideas , thanks for the vids Dony
Trickier then I thought! Nice video
@RockinGuy1994 lol, i thought after, what if the camera was off, which has happened before, but i was happy it turned out good
mr. donyboy thank you very much, God bless you
+Radix Kurniawan you're welcome

You should Support or cushion the Rotor underside so it will come to rest on a padding..!
You just saved me some money! Thanks
This video was a great help thank you
thank you so much for this video its a big help for me
Koolbeans love the rope ideal to!!!!
Dude, you saved my life. Thanks!!
@BriggsMower usually the wire is fused in the coil
great tutorial
