ratsnst,

Perhaps you don't know us very well. Rest assured we "calibrated" (as you say) the hydraulic throw out bearing assemblies according to McLeod's instructions. We even made a few of them in a fit of stupidity (from solid bars of aluminum).

We know a few things about measuring piston heights and relating them to the distance of the pressure plate fingers (but we are always willing to listen to anyone who has any ideas to help us along).

Please see the following thread for a discussion of our measuring and machining capabilities:

Regardless, "calibration" (I assume you mean the measurement from the face of the bell housing to the clutch fingers has to match the height of the hydraulic throw out bearing assembly within specified tolerance) is not the reason the units failed. Bad seals is why they failed. As for crap shoots, we simply did the measurements first and ordered the right piston length from the start so we didn't have to send pistons back and forth too often--I don't like shooting crap.

I still have some of those dastardly McLeod units in the shop. Maybe I'll post a pic of the nasty seals as a warning...and now you have been warned.
