This new slave pivot makes the total length 20 thousandths longer, not 2 thousandths as I said in the video. The original part was 32 years old !! Recent drives show the clutch is operating smooth as silk !!
The test fitting of the pressure plate to the flywheel, found one of the threaded holes was rough. Running a hardware store tap through the hole made the diameter so large the bolt stripped out when it was torqued down. So the 8mm hole had to be repaired with a HeliCoil insert. The holes in flywheels, blocks etc, are not tapped, they are rolled so they fit the bolts tighter. This causes less cracking and failure.
