5 speed swap clutch issues

[Johnny Riviera]

I think what you are seeing as chewed up is a bit of grease on the hub that transferred from the input splines, and some on the collar which also had a thin coat on it. I will be back to it today and take another look though. As far as pushrod length, I don’t know what proper length should be so it’s hard to tell if it’s the right one. 

 

Thank you you again for all the input!

I had an odd noise develop with similar syptoms in my 4spd which ultimately accelrated my 5speed swap.

Similar grease marks, wiped them and saw an imprint of the clutch cover springs embedded in the surface of the throw out. I have a lot of theories about how this happened.. no proof. The bearing is otherwise OK and had been fine since I had installed it in ~08 until '18. Clutch had minimal wear as did the cover, pivot, flywheel etc.

I had the same problem, and was putting a five speed in to fix it as well, and decided to change the pilot bearing also. Turned out my pilot bearing was in multiple pieces, and that’s what was causing the noise. But I don’t think you could see that the pilot bearing was bad until it was taken out, so if it looks good from the outside it might not necessarily be good

Didn’t get a chance to get out and work on it yesterday. Will keep everyone posted. Thanks again for all the ideas!

One more question    Did you machine the flywheel?   If it is too thin, the disc will hit the flywheel bolts

Well, it seems it is Stephers for the win. See pics. I still need to nmeasure flywheel thickness, but I’m pretty sure Aardvarc supplied me the correct disc.

Thank you all for the suggestions!

So I measured my flywheel and it appears to be 11mm thick in the friction area. I read elsewhere on the FAQ that minimum is supposed to be 14.5mm so definitely too thin.

Interestingly, I also noticed that the springs on my new disc protrude much more than the ones on my old disc. Even though the number on the old disc interchanges to the same number as the new one. 

Interesting. I think 3.5 more mm of flywheel will solve it, but the protruding springs really make for less clearance to begin with!
