At about 2:05 "...resistance in your clutch is so high that it is causing that switch to heat up and actually melt ....". Higher resistance would cause less current flow which would lead to less heat. Otherwise, I really like this presentation. The author seems like a very good down to earth person that really wants to help others.
That is interesting Chris's....I collect old Lesco walk behinds. My favorite are the 54" suspended decks. Couple years back I got sick of the electric start and put a pull start smaller engine on one and reduced the deck down to 48". (Decks are cool on this design...they pop on and off...I used a 48). But I had a little trouble with the PTO... I wonder if you just explained what is happening. tHanks
A good video sir. Those are supposed to have a 12 thousandth clearance between the top and lower clutch pieces. They can be a pain to get adjusted. Adjust each nut at a time. Sometimes it feels like its good, then check another side (3) and one side is too tight. I have with well worn PTO's tighten to .008. And get a little more use. More than .008 and they won't disengage. One more point, if you change from a 1 inch crankshaft engine to a 1 1/8 crankshaft that bushing piece can come in handy. I changed out a 12.5 Briggs for a Kohler V twin 25 horsepower. I thought getting a drive pulley for the 1 1/8 would be easy, it wasn't. I used the top pulley that came with the engine (for the transmission belt) and had to weld that short piece to the Kohler pulley. Then cut the pulley off my 1 inch ( for the mower deck ) 😂and weld it to the short piece. It didn't look good, but was able to make it run true, no side to side or up and down wobble.
I wonder what would happen if you put the whole thing in a bucket of white vinegar overnight, rinse it really well, maybe lastly a dunk in some alcohol to help thoroughly dry - they use this technique for cleaning rusty gas tanks
Great video Bob, I prefer the adjustable gap on the Ogura Clutches versus the fixed gap on the Warner Clutches. You could close the gap on an Ogura when the electromagnet got weak. Now everything is sealed so as not to tamper with it!
Good video , a wise man once said ," don't use force , get a bigger hammer " ! Been my mantra for 60 years , have a good day and keep up the good work !
Thanks Doublewide6! I've wondered how these pto's work. Another great demonstration of troubleshooting from you that can possibly save us DIY's some money on keeping our equip running. Thanks again for sharing!
The fix for that clutch should have took about 10 minutes to fix. When the clearance gets too wide the magnet will not pull it in. I will set them at .015 at about .050 they quit working.
I have four of these that have been waiting over a year for me to mess with them. Turns out...that the parts inside can fit different housing. So we fixed on with the parts of a different sized donor. They are so expensive I save them all. tHanks for the video
And thats exactly why im doing away with any of my pto clutches i can replace a engagement cable more than a pto i can replace a leaver more than a pto i wouldn't keep wasting money on any pto
@@Mike-su8si I agree 100%. Every time I pull the electric PTO I think to myself...."Will this be the time you fail again?" I have older machines that simply have a lever....I love them. Who thought it would be a good idea to take something as easy to use as a lawnmower and complicate them?
@@Dancing_Alone_wRentals i don't know but someone thought of the pto way of ripping people off i know some people probably like pulling the button instead of pushing the leaver up but i don't like the electrical clutches its just another thing that can easily break
@@Mike-su8si Not only might it break....they seem to always break. I tend to buy everything second hand so I spot what seems to always break. I guess the engineers who design this stuff don't know that part of the world I live in.
If they work like a car air conditioning compressor it will need no more than probably 14 thousandths or so. At least that is what an old mechanic told me once when he fixed mine.
Question about the wiring shearing off as they enter into the electromagnet holding. It spun and they sheared off. How can the unit be opened so I can solder either to the old wires left or install new ones?
I just tested another clutch pulley and its looking good no chewed wires just needs cleaned up and put up for if someone may need it i don't but I'll clean it and save it for someone else
Thanks, I didn’t know the magnet engauges the key way. I was wondering how would the magnet alone had enough power without some kind mechanical connection. Helped me understanding it a lot better
Only thing other than broken wires and bad bearings I've found is some times the plastic coating on the magnet cracks and water will get in and rust jack it all up.
biggest piece of crap ever put on a mower,manual engagement never quits working but this pos will stop working just when you really need to cut your grass,hard to find a mower that doesn't have one of these today
Why work in a pile of dung? Sweep or wipe off the bench maybe? Love yer can of PB Blaster and maybe mention it another 10 times and you'd get shipped a case? I need one of those cans you can just pressurize with your own air line Followed the Link you provided! $65 Is pretty steep - Have to figure out how to make one fur cheap that works!! Where did you get that? "I Gotta have more prying!!!" Pry from both sides or you're just jamming it on harder. "Hang on!!" I got this on the outside and it belongs on the inside!" Good ideas well exercised. Thanks for the walk though! Very informative! Thanks Lee
Thanks for posting. My pto is having different issues but this video helped to explain how these are supposed to work. On an assembled electric pto where there are no adjustment fasteners, should the pulley rotate freely when it’s disconnected and on the bench? Also, do you have a video showing how you built that dc power supply on your workbench? That is very cool.
My PTO clutch doesn't have bolts. So I'm not able to adjust it. It has only on one side of the clutch heavy rivets with looks to be some sort of pre measured shim. Problem is the side that has nothing rattles.
Thank you for the visual before I take mine off/apart. I think (from watching your video) my clutch needs to be adjusted as it sounds like it is slipping.
Another good related video would be taking off a badly rusted pulley off the engine shaft that allows you to get to the magnetic clutch. If you have such a video, I would appreciate a link..
DIAGNOSING ALERT. My deck was making a god-awful screeching and clicking noise when the blades were engaged (more on the right side). Everything… spindle, idlers, etc seemed tight. Took off clutch and it appeared fine. Installed new spindle. Still making noise. Replaced new idler. Still making noise. Finally took off clutch again and disassembled. Plates appeared scored. MUST be the clutch. After replacing with new clutch…STILL making noise. $hit…. Turns out it was the metal cup just above the blade that keeps debris out of the bearing that wore loose and spinning. Probably due to mixing and matching different parts from different spare spindles there was a bit of play. Wedged a bit of twine around it (yeah, its Macgyvered) to snug it up and back to normal. Just something to keep in mind.

I love this video , this is exactly how I fix things , tear it down , look for obvious damage , clean it and reassemble and hope for the best 👍
Your video just saved me about $400.00 that includes the labor. John Deere pto jumped$ 80.00 from last year. Thanks buddy.
Here they are 135 higher
Dam shame to

The tractors which have these types of PTOs , also have a larger Stater because of the currant this draws . Thanks for the video .

except for ariens. they made one with electric clutch but with briggs engine with just the dual circuit stater.
We all learned something from this video.

Good explanation of how they work and troublshooting advice, thanks
thanks . i know someone who had one that would work fine when cold , but would not work when hot . adjusting the air gap fixed his .

Great job on fixing this pto clutch, with everything expensive it helps to see if the oem one can be repaired 1st and this one it needed cleaning.
Just what I were thinking too, this good wrench just confirmed it, thanks
Great video Bob, I prefer the adjustable gap on the Ogura Clutches versus the fixed gap on the Warner Clutches. You could close the gap on an Ogura when the electromagnet got weak. Now everything is sealed so as not to tamper with it!
Makes sense because the bigger the gap the more voltage it takes to keep it closed is my thinking
I like to adjust things and keeping them in spec
Good video , a wise man once said ," don't use force , get a bigger hammer " ! Been my mantra for 60 years , have a good day and keep up the good work !
Well done
I will try this weekend. I got power but soft engagement and loose pulley and washers rattle. Hmm
Awesome job breaking it down like that. You're a Godsend bro, thx a million.
Excellent video. Common sense stuff. It taught me how a PTO works and showed me how to diagnose mine. Thanks
Thanks Doublewide6! I've wondered how these pto's work. Another great demonstration of troubleshooting from you that can possibly save us DIY's some money on keeping our equip running. Thanks again for sharing!

You need to upload a video showing the ten-minute fix. This guy’s at least showing us SOMETHING.
@@ButterflyMatt I don’t think that he was inferring that this guy took too long.
Great info, years on HD motorcycles but never did a PTO set up, thanks.

Nice video DW, I've never actually taken one apart so this was an extra interesting video, thank you for the demo brother. 👍
Thanks for watching!
Always a pleasure bud.
I would’ve check the air gap first before doing anything.
That's exactly how my Dad taught me. Good job

A very good practice to work in a clean environment 2 seconds to clean the grass and crap off the Bench 😮💨
Great video. That could be a money saver
Only thing other than broken wires and bad bearings I've found is some times the plastic coating on the magnet cracks and water will get in and rust jack it all up.
Very good tutorial and recon of that PTO. Thank you.
biggest piece of crap ever put on a mower,manual engagement never quits working but this pos will stop working just when you really need to cut your grass,hard to find a mower that doesn't have one of these today
Absolutely perfect !! Thanks brother !!
Thanks for the he advise from Dave new Zealand
Can crankshaft seal leaking engine oil on the electrical solenoid wreck it? Thanks for the help 🙂 👍
Probably not but it can cause it to slip.
Why work in a pile of dung?
Sweep or wipe off the bench maybe?

Thanks

Mine is stuck on but I will check the switch first I guess I been having so many problems the last year my yard is so long
I’ve put them in bucket of white vinegar to clean them up
Wow I just posted that
But you need to clean the bearings and lubricants applied 😊after wards
I used my battery charger for testing mine
Taught me something new!Glad to see you doing a video.
But i don't like pto stuff i like leavers and cable engagement i don't like electrical engagement
Learn something new everyday
Good fix Bob.
Cool thanks
That works the same as the clutch on a compressor what are the air conditioner in your car
Nice fix.

Stay well, Joe Z
Yo yo .. hi Bob.. good video my friend.. sometimes all things need is a good clean..
Good troubleshooting video!!

Thanks, it was helpful and informative. 😊👍🚜
The truck radio is the power supply? It runs on 120Vac?
I stated that wrong it has a computer power supply 120V to power the radio and the DC power.
My PTO clutch doesn't have bolts. So I'm not able to adjust it. It has only on one side of the clutch heavy rivets with looks to be some sort of pre measured shim. Problem is the side that has nothing rattles.
Enjoyed the video. Thanks for sharing.
If coil bad I remove brg and save it if it’s good
At what point is the pulley too rusty to use? I just replaced a clutch where the pulley was so rusty it had a hole rusted through it.
Thank you that was good
Nice video good things to know
Like this vedio, great help save my money. Thanks
Great detailed video!
Thank you for the visual before I take mine off/apart. I think (from watching your video) my clutch needs to be adjusted as it sounds like it is slipping.
what are you using to power up the pto on the bench?
Great video
Great video thanks for sharing 👍
where is the link to using a bigger hammer ?
Great video 📹...
Thank you very much !!!!
What should the amp draw be?
try 50/50 ATF-acetone (any atf) better than pb blaster. what were specs. for gap ? did you check it ?
maybe should have taken apart a working one to see what should move.
I hope this is going to save me $140. Thank you!
Excellent 👍
Great video!
Great video!!!!!!!!!!!!
Another good related video would be taking off a badly rusted pulley off the engine shaft that allows you to get to the magnetic clutch.
If you have such a video, I would appreciate a link..
I have 2 videos on the subject.

So my coil is reading 7.5 ohms. Is that considered bad?
Should be between 2-4
It's the gap between the magnet and the clutch it's too far apart.

Looks like when you did your first check and everything was tight you didn’t grab those cups
@@doublewide6 Yep...live and learn
Take brging out and clean them if good
so, you can just dunk it in a ultra sonic cleaner?
Cool!
13-15 feeler gauge another video I watched he said 14
It's literally an ac clutch adapted to a lawn mower.
My pto engages fine, but then it rotates and breaks the wires. It's on an old Simplicity.
What is the result when your continuity is 0
I think my pto is so rusted it cutting the belt
👍
I didnt know tractors got paid time off
sweep table please..
IF I WERE YOU SPRAY RUST REMOVER😱😱😱😱👍👍👍👍LET IT SIT FOR A DAY👍👍👍👍👍
Lost me at "I don't know how these work".
Still fixed it tho
.010 to .014
