Help needed with a 78 J20 clutch and bearing retainer
I have a problem that I have been working on for some time now, and I have come to the conclusion that I need to ask for advice.
My 360 V8, J20 had a problem where the Transmission input shaft bearing retainer needed to be replaced.
I bought a replacement bearing retainer from Bluimthals a while back. To make a long story short, the shaft on the bearing retainer where the TO bearing slides was worn out, and it broke off. I could not find a replacement one anywhere. Bluimthals had a similar one that was 10" long (the same length and same ID), but the OD was was larger.
After a lot checking around, I was able to find a larger TO bearing that was similar to original bearing and would fit over the new, larger dia. shaft on the new retainer. I got it all put back together and now the problem. It will not release the pressure plate.
I adjusted the clutch all the way up, but no matter what I did, depressing the clutch peddle would not disengage the clutch. I took it back apart trying to figure out why. I could not see where the problem was. I thought the clutch disc was in backwards, but it was not. After I got it put back together today, I was hoping the best, but there was no change.
I am going to take it back apart next week and do some more thinking. It crossed my mine that maybe the problem is the TO Bearing. It is larger in diameter than the OEM one by about 3/8 to 1/2". I didn't measure it, but I will when I tear it back down. I was thinking that the larger diameter will not push the PP arms down correctly, and is binding. The PP and clutch disk are new. A long shot is that the PP is not the correct one, but I compared it old the old one and it looked very much the same.
Anyone have any thoughts on this? Any suggestions would be appreciated.
