1000 Clutch Slipping

[Bob95065]

I have a CC 1000 that I got back after my dad and finally brother had it. It came to me not running and in very poor shape. The clutch needed work so I repaired it. I did the following:

I replaced the throwout bearing, clutch disc and surfaced the pressure plates. I also put a wide frame release lever in it for now. I'll put the correct QL lever in next time I order parts. I had to replace the release lever because the throwout bearing had locked up and my brother kept using the tractor anyway. I am glad the release rod linkage broke and he stopped using it.

I bought parts from ************************.com. The disc I bought is a fiber disc. The original disc was laminated with a thin steel disc in the center. It was delaminating so I decided to replace it.

The pressure plates were warped, rusted and uneven. I used a friend's lathe to surface them flat. They had and even, smooth finish when I was done with them.

The teaser spring and loading spring looked good so I reused them.

I was working with a small Brinley box scraper and the clutch started slipping. The slipping occurred on take off from a stop. In 2nd gear I could let the clutch out and there was a delay of maybe 5 seconds before it started to move. I heard no noise or smelled burning clutch material.

I am worried that surfacing the pressure plates may have caused a problem. Is it ok to run smooth plates? Should I have left them somewhat rough? Has anyone else experienced this condition? Any help is appreciated.

What condition is the drive shaft in?
Is there any wear on the drive shaft where the throw out bearing goes?
Does the throw out bearing slide easy where the throw out bearing goes when you rebuilt it?

As many of the guys here will tell you I have turned hundreds of plates (my own and for others) and have never had a problem with smooth plates (unless someone didn't complain to me when there was a problem).

When you turn plates they are smooth but they are in no way "slick" (they look more like and old record album) all of those little tiny groves and burrs should cause it to really "hook up" well.

If your lever isn't binding or getting caught on something, then I would suspect the spring or drive shaft to be the problem.

With the engine not running, get your face right down close so you can watch as you push the pedal down and let it up again.

Or loosen the nut that pulls the lever back and see what happens.

Good luck and let us know what happens.
