Cub108 - Drive Clutch questions

[Dave_With_Cub108]

Hello Cub Enthusiasts! The clutch on my 108 was last replace in 1990. The clutch is slipping now.

So, if I replace the friction disk, would you recommend replacing the throw out bearing and other clutch-related parts?

The clutch disk is about $46 and the throw out bearing is about $50 at CubParts.com. A little pricey but I don't want to put it all back together only to have to service it later.

You might as well.

I wouldn't do one unless I did. You should also have the clutch plates "turned" or machined, and check the driveshaft out. Sometimes they are wore, or even bent. Also, not uncommon for the teaser spring to be broke. You'll have $125-$150 at least in it doing it right.

It really does kinda suck (cost wise) but yeah, if you're going to replace anything, it really is best to do it all.

This is not an area where you want to "skimp" if you do it all, you should get many, many years out of a rebuilt clutch/drive shaft assy.

Agree, take it apart and inspect. Replace everything that is worn. Put back together and forget about it for about 25 years.

I like working on my Cub just as much as the next guy but not when it comes to rebuilding the clutch, do once, do it right. Use this time to upgrade the spring if needed also pay close attention to the driveshaft, Mine had to be replace because the holes were oblonged at the rear coupler.
