105 engine power take off

[DoubleO7]

In the engaged (or relaxed) position the fiber disc with teeth meshing with the S/G pulley basket is squeezed in between the pto belt pulley and the metal disc portion of the pto unit on the engine side.

Just like on an automotive manual transmission clutch assembly.
Except the power is being transferred from the inner diameter of the driver (S/G pulley basket) inwards to the pto belt.

The bearing should cost less than $20 so I would replace even if the old one "felt" good.
How much slop between the fiber gear and the S/G basket pockets?
If all of the teeth are there and it can only move like 1/8" back and forth in the basket pockets, I would reuse it.

The coil springs push that metal disc away from the pto belt pulley so that it does not drive the fiber disc/gear.

I've got an old wooden hammer handle that the head rotted off that I use...it's still strong enough to be used as a soft punch to tap off the PTO. Normally I tap one one side, spin the engine (spark plug wire removed) and tap it some more.

Since I've never used this cub cadet before with implements, does the clutch pulley always turn? I guess that's what has me confused. Thanks again!

The PTO should be left on if no implement is on the tractor. If left disengaged with no belt, it will wear out the buttons on the lever and the clutch. It rely's on some of the friction for the implement to keep it from turning when disengaged. Otherwise, the pulley should not turn when it's disengaged. Make sense?

Thanks, I'll double check tomorrow but I'm pretty sure that the pulley turns when the lever arm is in the forward position (disengaged).

[steved]

I said that wrong, forward lever position is engaged.

I learned that two weeks ago.
Transplanted a different engine into my 127.
Had to see if it would start before putting the mower and belt on.
Was not running more than ten or 15 minutes with pto disengaged before I noticed a near new fiber button pretty much worn away to zero.
Without the drag of a belt to the mower or thrower, the grease and balls in the pto bearing are enough to turn the entire pto sheave.

Good info here. Mine was/is turning "engaged" at all times. Just installed a belt today and it seems the clutch is locked up. Looks like it's rebuild time. Hope I have an easier time removing it

They are not all that difficult to work on, just did the one in my 149. It was a first for me. You can see what I did, thread sort of jumps all over the place with other issues.

Ditto on replacing the bearing. The consequences of a failure,after all your work can far outweigh the damage a seized bearing can do. DON'T ASK ! Good luck.
