2 Install bearing inner race (2) on pinion shaft (1).

3 Install bearing outer race (2) in differential carrier (3).

4 Install pinion (1) and fl anges (4) and (5) complete with outer
bearing races (6) and (7) in differential carrier (3) and, using a
depth gauge “A”, measure distance “X”.

● Rotate the pinion in both directions to seat the bearing.

Place onto the outer bearing race (7) on the crown wheel
side a cylindrical pin “C” 2.5 mm (code 2.1651.109.0) in
diameter, to make up the difference between the outside
diameters of the bearings (7) (Ø90) and (6) (Ø85).

5 Calculate distance “D” from the differential’s axis of rotation to
pinion head (1) with the following formula:

D = X - R

Where: R = 45.00 = radius of bearing (7) on the opposite side to
the crown wheel

e.g:

● Dimension “X” = 107.75 mm

Radius “R” = 45.00

D = 107.75 - 45.00 = 62.75 mm

6 Remove pinion (1), outer bearing race (2) and fl anges (4) and (5)
and form a shim pack (8) of thickness “S” calculated using the
following formula:

S = D - Theoretical value + E

Where: S = fi nal shim pack thickness (8)

D = measurement calculated at point 5

Theoretical value = 61.00

E = dimension stamped on the crest of a tooth of pinion (1)

Example 1 (negative “E” value)

● D = 62.75 mm

E = - 0.05 mm

Theoretical value = 61.00

S = 62.75 - 61.00 - 0.05 = 1.70 mm

Example 2 (positive “E” value)

● D = 62.75 mm

E = + 0.15 mm

Theoretical value = 61.00

S = 62.75 - 61.00 + 0.15 = 1.90 mm
