Calculate the required shim thickness as follows:
the nominal mounting distance
L
deviation from
nominal (as marked on the end of the pinion in
millimeters, or - number) = required
mounting distance. The measured distance (from
Step 5) - the required mounting distance =
required shim thickness. The measured distance
must be within 0.03 mm (.001 in) of the required
mounting distance. If it is, the correct thickness of
shims have been installed. If the required
mounting distance is greater than the measured
distance, remove some shims (19). If the required
mounting distance is less than the measured
distance, add some shims (19).
EXAMPLE 1:
78.00 mm (3.071 in) -
nominal mounting distance
- 0.09 mm (.004 in)
-
deviation from nominal
(marked on end of pinion)
77.91 mm (3.067 in) -
required mounting distance
78.10 mm (3.074 in) -
actual mounting distance
from Step 5
- 77.91 mm (3.067 in) -
required mounting distance
0.19 mm (.007 in)
-
thickness of shims
to be installed under cup (18)
EXAMPLE 2:
78.00 mm (3.071 in)
-
nominal mounting distance
- 0.09 mm (.004 in)
-
deviation from nominal
(marked on end of pinion)
77.91 mm (3.067 in)
-
required mounting distance
77.91 mm (3.067 in)
-
actual mounting distance
- 77.91 mm (3.067 in)
-
required mounting distance
0 mm (0 in)
-
thickness of shims that need
to be added or removed
from under cup (18)

If the original bearings and ring gear and pinion
set are used, install bearing cups (18) and (20)
with original amount of shims (19) behind bearing
cup (18) in the housing assembly. Press bearing
cone (13) on the pinion shaft.
8.
Do Steps 2-5. To calculate if the installed shims
are the correct thickness, proceed as follows : the
nominal mounting distance
L
deviation from
nominal (as marked on the end of the pinion,
or - number) = required mounting
distance. The measured distance must be within
0.03 mm (.001 in.) of the required mounting
distance. If it is, the correct thickness of shims
have been installed. If the required mounting
distance is greater than the measured distance,
remove some shims (19). If the required mounting
distance is less than the measured distance, add
some shims (19).
9.
After the pinion depth is correct, remove tool (D) and
pinion shaft (12) again.
10.
Press bearings (25) on the gear shaft (26).
11.
Install the gear shaft (26) in the housing. Install
the snap ring (24) on the gear shaft (26).
