Hello all,
I am in the middle of a project and I need some help.
I am changing the clutch on my 66 318 new process 435 set up, and I am in uncharted territory. It is a hydraulic set up, and I need to know what kind of clearance everything should have. I am replacing the clutch because the first one went out prematurely. Possible reasons were: bad throw out bearing; not enough clearance for the bearing when it backed off the pressure plate (it may have been riding it the whole time); not enough room when the pressure plate is opened and the clutch is disengaged. My confusion is due to the fact that I don't have the original linkage between the slave cylinder and the throw out arm. How far should the throw out bearing be from pressure plate when the clutch is engaged? How far does the pressure plate need to be compressed when the clutch is disengaged so as not to generate excessive heat? I am able to spin the clutch by hand fairly easily, but I can hear some rubbing, is this normal? I am dumb about clutches (this is the first one that I have done solo) so I might be asking real simple questions, don't underestimate my ignorance. Finally, what is supposed to pull the throw out arm back to the slave cylinder?
A stout spring? (there is nothing on mine right now, and just so you
know this engine and tranny aren't original. they are in a '54 M37, and I didn't do the swap, so I don't know the original configuration) Is there a worry about having the clutch disengaged to far? I hope to get this right, as it is a good deal of work to replace. Anyhow, feel free to email me any answers as I will try to get this thing done this weekend (God and Fiancee willing). Thanks, Peter Galmish
