Pinion Depth Setting
1
Place new pinion head inner bearing assembly on a flat
surface and position service tool 892/00174 over the
bearing. Measure gap
A
(e.g. 0.20 mm) and add this to
the cup depth stamped on the tool (e.g. 30.01 mm) to
obtain the bearing depth.
2
From the face of the pinion, obtain the etched deviation
figure
B
(e.g. + 2) which is in units of 0.01 mm. If
positive, add this to the bearing depth; if negative,
subtract from the bearing depth.
3
Obtain the deviation figure
C
(e.g. - 1) stamped on the
differential housing bolt flange. If negative, add to
bearing depth; if positive, subtract from bearing depth.
4
Subtract the total of the above figures from the
standard value of 31.19 mm. The result will be the
thickness of shims required behind the pinion head
bearing cup.

Note:
In the event that the setting data stamp has been
ommited from the drivehead casing, adopt the following
setting procedure:
Revise the shim pack size by the difference in setting height
marked on the old and new crownwheel pinion sets.
