6. Use master gauge 385/30 to set the measur-
ing mandrel to the setting dimension (in the
example: 70.27 mm). Zero the dial gauge (3 mm
measurement range) with 1 mm preload.
8. Fit side transmission cover without O-ring
and fasten it with four screws tightened in
diagonally opposite sequence.
Note
Do not use a hammer when fitting the side
transmission cover (the final dimension plate is
held by magnets and could fall off). Move the
cover to its installation position only by uniformly
tightening the screws.

10. Carefully turn the measuring mandrel until
the dial gauge extension is at right angles to
the front face of the drive pinion head. It is
at this point that the dial gauge pointer
reaches its max. deflection (reversal point)
and the dial gauge can be read off.
Note
Maximum deviation of the measured value from
the set installation dimension "E": ::t 0.04 mm.
