3 Series E30 324td (M21) TOUR
To measure preload of plate springs, install special tool
33 1 441 (threaded plate) and spindle. Tighten spindle by hand.
Mount holder with dial gage.
Set dial gage to zero with preload.
Tighten spindle until diaphragm springs are pressed flat.
Read dial gage. Loosen spindle.
Turn shaft gear and measure again at several points.
To ensure that the plate spring is not block-preloaded, clearance
of 0.03 ... 0.1 mm must be available.
The lower value would be ideal.
Repeat measurements on opposite shaft gear.
Excessive Clearance:
Install thicker shim.
Insufficient Clearance:
Install thinner shim.
Shims (2) are available in gage steps of 0.05 mm.
The opposite end is determined in the same manner.
