<VV> Clutch Chatter

[Smitty]

From: RICHARD <rbeth at comcast.net>
I have 63 Corvair that has clutch that slips on a hard pull. I also have 
leaking seals from
either the Engine or Trans. Think oil got on the clutch plate and that is 
what's making
the clutch slip. The clutch also chatters when engaged.
The clutch pressure plate flywheel(Bolted) has been replaced when the motor 
was
overhauled 40 thousand miles ago
Also a harmonic
balancer was installed.Some one told me that the rear motor mount
was broken. Will the broken rear motor mount make the clutch chatter. Also 
if a
harmonic balancer is put on a 63 does the rear motor mount have to be for a 
64

Smitty Says;  Richard, oil on a clutch can indeed make it slip and chatter. 
Bad rear mount and front mounts can also, along with bad U joints and other 
things.
The metal stepped motor mount (to clear the damper) should be changed along 
with the rear rubber mount as the hole and stud for attaching the mounts are 
located different 63 and 64.  You can put a damper on with the 63 assembly 
but then you have the inconvenience of not being able to change the fan 
belt.
