I am investigating an early 50’s Super C clutch noise. Upon take down the clutch components all looked good and only slightly worn as they was replaced 3 years ago. The flywheel step was confirmed as 1.188” as provided by earlier posters (thanks!).
The noise was the clutch rod (inside the torque tube) which is attached to the yoke below the release bearing hitting the adjustment bolts for the pressure plate when the clutch is engaged. The clutch does not slip. No excessive play in yoke or yoke shaft. Some play at clutch pedal to housing pivot point which should not affect this problem.
It would seem that the pressure plate fingers should be extended further outward such that the release bearing contact and clutch disengagement would occur prior to the clutch rod contact with the pressure plate.
I have read the pressure plate fingers can be adjusted (27/32”). If clutch is assembled into the flywheel with pressure plate installed how this measurement can be easily made. The distance as I understand it is from the fingers to the bottom surface of the pressure plate when installed.
When installed you can not measure to the bottom surface of the pressure plate. Unless you measure the thickness of the clutch disc and then find/make a “dummy” piece the same thickness (like ¼ plywood disc) and substitute this for the clutch disc for measurement. I would like to check this dimension.
Do I have the correct parts installed?? How do I confirm? 9” Rockford clutch plates believe had different springs could the springs be not correct?
