Looking for some clutch help. I recently disassembled a quartermaster Pro 7=
.25 single disc clutch, not from my car. I have no experience with this sty=
le of clutch. Upon disassembly I observe that the flywheel insert, clutch d=
isc and pressure plate only have had contact on the outer 3/8 " diameter. =
Upon further investigation the flywheel insert surface is flat. The clutch =
surface thickness is uniform but if I lay a straight edge across the face o=
f the Quartermaster pressure plate it cups outward. My initial thought was=
"bingo" this would cause the wear pattern I am observing. Must be somethin=
g out of whack with the pressure plate insert. I contacted quartermaster a=
nd described what I saw and they were not much help other than "something m=
ust be warped". I was getting ready to order a replacement pressure plate i=
nsert but I stopped over to Jason's shop and saw that he was working on a c=
ar that also ran a quartermaster Pro 7.25 clutch but this was a double disc=
. I took it apart and all components had even wear across the faces as one =
would expect. I layed a straight edge across the pressure plate out of thi=
s assembly expecting to see a flat contact surface and was surprised to see=
the same cupped condition where the outer pressure plate surface would con=
tact the clutch disc first as the one at home. Now I am at a loss as to wha=
t would cause this improper wear pattern. Any experience with this?
