PTO and clutch bearing replacement: Cub Cadet 123

[knucklescraper]

NOTE: this post should be in IH Cub Cadets GT ... can't figure out how to move it there. I put it in the wrong group.

Questions:

1. How is the pto clutch bearing removed?

2. Should the locking collar be replaced when replacing the bearing?

3. Any installation tips? (I've read the service manual instructions). Is putting anti-seize on the shaft, on the bearing, and on the setscrew threads a good idea to make future removal easier?


Background:

It didn't take long for a new problem to occur since my last post.

My mower deck spindles aren't turning fast enough for the blades to cut. It cut fine before the previous engine broke.

I removed the pto from the engine.


Observations:

1. the pressure spring, throw-out levers, and screws are all loose.

2. the pto is the type with the single pressure spring.

3. the wear button is gone (not the thrust button but the little piece that contacts it and fits into the engaging lever).

4. there are TWO friction disks adjacent to each other.

5. the clutch bearing isn't quite flush to the end of the shaft. it protrudes out over the end of the shaft a little.

6. when rotating the clutch bearing, it is a little draggy, not smooth.

7. the clutch bearing wobbles a little, that is, there's play between the outer race and ball bearings when pushing axially on the top of the bearing and pulling axially on the bottom (back and forth).


My Thoughts:

It seems the pto that was on the replacement engine I put in this tractor wasn't adjusted properly and I didn't notice.

I think I should replace the clutch bearing.

I plan to replace the pto with the same style one from my broken K301AS engine which was working fine before the engine went kablooie. I'll fix the loose pto later. I'll probably take it apart tomorrow.
