Just need to know what gap to adjust the clutch/flywheel clearance in my '70 Duster 340. It's been 8+ years since I adjusted my son's B-body, which I "think" was set at .040". Is this correct?
Yep, about that much. I don't measure but check the throw out bearing to pressure plate finger gap at rest. Just some, not too much. Probably around 1/8". Cycle the pedal a few times and look check again.
MP say's .060" for a B&B. I use that as a starting point and adjust down from there. My LW bell is an old 3 piece BTW. Important to not over adjust and bottom out the fingers, possibly bending them.
I just got through installing a 10 1/2 B & B in a 72 duster 340 car, We set it at .040 initially & drove it about 60 miles neighborhood stop & go & some highway speeds. I was quite happy with it & so was the customer. I let it go out the door.
