Fit dial gauge with measuring fixture special tool 00 2 530 on
cleaned cylinder sealing surface and set under pretension to zero.
Clean piston at measuring points (1 and 2).
Fit dial gauge at measuring point (1) on cleaned piston and
determine highest point by rotating crankshaft.
Measure and note down piston clearance at measuring
points (1 and 2) on all 4 pistons.
