SHIM SELECTION

EXCEPT FOR USA AND CANADA
Pinion gear shim
1. Find pinion gear shim thickness (T3) by
selecting shims until the specified mea-
surement (M) with the special tool is
obtained.
2. Install the pinion on the drive shaft and
tighten the nut to the specified torque.
3. Assemble the pinion height gauge with
the drive shaft and bearing as shown in
the illustration. Bolt the bearing hous-
ing to the special tool with at least two
bolts.
4. Using a digital caliper at the specified
measurement (M) established above,
measure the distance between the pin-
ion height gauge and lower surface of
the pinion as shown.
5. P is the deviation of the lower case
dimension from standard. It is stamped
on the trim tab mounting surface of the
lower case in 0.01 mm units. If the P
mark is missing or unreadable, assume
a P mark of “0” and check the backlash
when the unit is assembled.
Example:
If M is “32.10 mm” P is “+2”, then
T3 = 32.10 – 31.5 – 2/100 = 0.58
