What would be considered an acceptable tolerance when adjusting pressure plate fingers? I had suspected something was off when reassembling everything after putting the new engine in and recently the clutch started to chatter. Turns out none of the adjusting nuts were staked and all of the fingers were around 3/16”-1/4” … way off the 11/16” that they should be. The kicker is the note that came with the pressure plate said “DO NOT ADJUST” …

Anyway, I made up a tool to gauge the depth, was shooting for 11/16 (.6875). The tool came in at 0.692, not bad. I have a couple fingers adjusted to 0.692+0.004-0.000. Is that close enough or should I aim for a tighter tolerance like 0.002?
