Secure special tool 00 2 500 (dial gauge holder) and measure
torsion flank clearance,
refer to Technical Data
Caution!
The contact pattern is always the indicator for perfect gear
adjustment,
refer to33 12 551
To check the tooth contact pattern, coat the crown wheel teeth
with printer's ink, turn in both directions several times and stop
crown wheel suddenly with a piece of hard wood.
Correction of torsion clearance,
refer to Technical Data
and contact pattern is performed by altering the thickness of both
shims (1).
If backlash is too great, install a thinner shim on the crown wheel
end.
If backlash is too small, use a thicker shim on the crown wheel
end.
Axial displacement of the crown wheel of 0.01 mm signifies a
change in tooth flank clearance of 0.0076 mm.
Caution!
The total thickness of both shims may no longer be changed.
If a thicker or thinner shim was required to correct the tooth
contact pattern, the total thickness must be corrected with the
second shim, since otherwise the friction torque of the
bearings would be changed again.
