What happens when you don't clean it.

Okay. How do you know?

I've had a couple PTO bearings lock up over the years and the only thing that happened was I couldn't disengage the PTO from the engine.

Mike if the bearing in the pulley locks up as you said you can't disengage the PTO, but if the bearing that is on the inside locks up it will stop the engine because that part is held to the engine by an anti rotation stop. I bought a 1641 that the owner told me the engine was locked up, turned out to be a bad bearing. The red arrow points to the bearing I'm talking about. This style and the triangle shape PTO will both do the same thing.

I've not seen a PTO on a Cub that looked like that one. I'll have to study on this a little. Still don't see it but if you had it happen, I believe you.

This is what the 1641 had. Both types have 2 bearings, if the bearing on the inside takes a crap the engine with stop and act as though it is locked up. Take the PTO off before you condemn the engine.

Guess I'm brain dead. I've only found one bearing in those clutches. Just had one apart a couple days ago.

I'll try harder to understand.

The 18 mag engines only have one bearing in the clutch, the v-twin engines have 2 bearings in the pto clutch.

Maybe this will better explain it. If the bearing inside the field coil on this style locks up the engine shes a no gonna turn

That is now my thinking. As I stated before on my friends car. The compressor locked up and would not allow the engine to turn over. I agree with Sam, if the inner bearing locked up to the outer shell it would lock everything up. Before I removed the deck the blades would not spin either. Now that the deck is off, they turn freely. Which that alone tells me something's up with the PTO. We'll find out for sure today. As I remember this unit had issues with one of the seat safety switches not hooked up, so till I figured that out had to tie the PTO switch in the run to keep it engaged. Am wondering if over time that over heated the PTO. The tractor was run for over a year that way. Just a thought.

I see said the blind man. The PTO clutches on the mag/command Kohlers I've had off aren't made like that. Only one bearing. I changed out a clutch on the 1641 maybe ten years but don't remember much about it.

I agree with you about the inner bearing could lock up the engine.
