The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Throw Out Bearing/Pressure plate help!

I am trying to mate together a stock 4spd transmission on my 65 C10 onto the engine. I got the truck in pieces from my dad so I could have a wrong part but it is driving me crazy!

The problem is the bell housing will not bolt to the engine without the throwout bearing placing crazy amounts of pressure onto the pressure plate. It almost seems like I was sold the wrong throwout bearing or is this normal? I will try and attach a pic of the throw out bearing the parts store sold me. I'm pretty sure the clutch, pressure plate and everything else is right because my dad kept everything together. I'd appreciate any help.

It is possible you have the wrong throw out bearing for the pressure plate. There are two common pressure plates for our trucks, one use coil springs and the other a diaphragm spring. The coil springs require a shorter length TO bearing than the diaphragm, because of the length to the flywheel.

So what do I ask for at the parts store? They are clueless and say that this is the only one shown for our trucks. I guess I might have to order somewhere online. I can't believe this darn throwout bearingh issue has been screwing with me for like 3 weeks now.

I think I'd find another parts house. The last couple of clutches I've bought have been as sets, pressure plate, clutch disc, and TO bearing. When your truck was built it probably had a coil spring pressure plate, that was the norm. I'd guess that is what you have. I tried to find something online for you but all I got was big dose of frustration. There is about inch difference in length.

Hy krazymatt, what engine are you working with, the parts book shows a shorter throwout bearing for a 327 engine o.e.m. p/n 900018 (1 1/4" long). There are two different designs of diaphragm clutches, a flat finger design that would probably use the longer throwout bearing, and a bent finger design that would use the shorter throwout bearing, this design probably places the clutch fingers very close to where the fingers would be on the coil spring (Borg & Beck) pressure plates mentioned by LGriffin above. The Napa p/n BRG N3068SA is the crossover from 900018, hope that helps.

Thanks for the help guys. I finally just ordered one from Classic parts. They list the two different ones. I also wanted to update that today I mated the motor with the transmission and installed the engine in the truck. I had experienced a couple of broken bolts issues and a couple of wrong and missing parts but man do I feel accomplished today when I bolted in that engine. Now it's all down hill from here to get the old girl running. I just need to buy me a water pump, thermostat, hoses, and plugs and wires and I'll be able to fire her up.
