Hey guys. I just finished up a 2F motor rebuild for my 78 FJ40 and decided to pair it with an SM420. Everything seemed to go together easily without problems but my clutch is making a crazy loud high pitch squeal as I push in the pedal or let out the pedal. If the clutch is completely in or completely out there is no noise. I wouldn’t claim to be an expert but I’ve done a few clutch replacements and have never had an issue. Here are all the clutch parts I have in the cruiser:
EBI plate adapter, index ring
Nose cone sleeve
10.5” Chevy clutch disk
3 speed bell housing
4 speed clutch fork, slave cylinder, picot ball, etc
4 speed fly wheel (resurfaced)
4 speed pressure plate (original)
New pilot bearing (202RRE)
New Throw out bearing (Timken 613008)
Normally based on these symptoms I would assume the throw out bearing is bad and I suppose it could be. It is brand new but maybe it was bad to begin with? It seemed to spin fine out of the truck and still seems to spin fine inside the truck. With the inspection cover removed the clutch appears to operate as it should. Clutch fork pivots pushing the bearing into the pressure plate and the clutch disk spins freely.
Any thoughts on what I can check for before removing the transmission? What should I look for after removal? With everything being new other than the pressure plate I’m not sure what I’m going to find. Thanks for the help.
