Title: Clutch issue on TJ
Post by: sandersen on September 13, 2020, 06:43:44 PM
Finally dropped my rebuilt 353 into TJ this weekend, with new clutch and disc.  Resurfaced flywheel as well. Nosed in the tranny today, it slid in real nice.  But there's not much pressure to the pedal...and really can't shift the tranny.  I checked the throwout bearing and that looks fine.  I must have missed something. Afraid I have to pull the tranny again.  Any thoughts would be appreciated. Thanks

I done that when I rebuilt the engine in my tractor the problem was I put the clutch disc in backwards the hub was tight against the flywheel.

I'm fairly certain I got the hub facing the tranny.  But I appreciate the thought. I did not mess with the fingers of the clutch at all.  ?  I'm stumped.

Is the throwout in backwards?

Is the pedal free travel adjusted right ?  If the free travel isn't right the throw-out bearing won't push the pressure plate fingers in for enough to release the clutch.

Mike, I checked that to be sure through the plate you can remove at the top of the tranny. Flat side of the bearing is facing the engine which I think is right but correct me if I wrong. Thanks.

That may be the issue armechanic. My pedal goes down about three inches before any real pressure is felt and then not much at all. I had to have the flywheel ground down quite a bit too so maybe that's why the pedal needs adjusting. I'll try to adjust the linkage I guess and see if that helps.  I'm hoping for some good pressure right up top of the pedal I believe, right?

Im not familiar with skidder trans.    Do they have clutch brakes?  

A roadranger wants 1/8" slack between the fork fingers and bearing when foot off the pedal, and 1/2" between the back of brake and face of input shaft retainer cover.  Id say an 1/8" is a good generic starting point for pedal slack in general.
