Are you using a Cub Cadet bearing?
There is nothing wrong with the way IH Cub Cadet design and manufactured the clutch-driveshaft assembly. Something is not set right and there are some parts that need replace if you are loosing the sheild off the throwout bearing.
When I rebuild a clutch I do the following:
1. new clutch disc-garden tractor pulling sites that sell parts have a cheaper price on clutch disc.
2. Clutch disc are trued on a lathe (only way to true them).
3. new springs
4. pilot bushing is replaced if needed
5. pins in drive plate are replace
6. yoke is inspected-replace if needed
7. clutch lever is inspected-replace if needed
8. new throwout bearing-I use Cub Cadet bearings
9. driveshaft is inspected-replace if needed
10. all pins in the driveshaft are replaced
I change several things on my IH Cub Cadet 100. The clutch disc is made out of kevlar material. I replace the big factory spring with one like miller has on his web site. The spring is rated 450 to 500 pounds. Stock spring is rated at 200 to 250 pounds. I use a split collar to hold spring tension on the clutch instead the pin that Cub Cadet used. The area where the yoke connects to the tower has been beef up so the that area doesn't flex when I push the clutch in. I do not put the spring that goes on the driving disc. My 100 pulls a 10 inch plow and the engine has been modified.
My Wife likes to drive the 100. She has no problem with the clutch set I have in it. Clutch slipage is next to none wit his set up.
