Drive Pinion
Height Adjustment
NOTE: If the drive pinion and ring gear are replaced
(always as a set), the height has to be adjusted.
Select the proper shim as follows:
First, calculate the difference in size between the old
shim and the new pinion.
The last number (see ill.) on each pinion is the plus (+) or
minus (-) tolerance in thousands of a millimeter. So, a
pinion with +20 is 0.02 mm larger and a pinion with - 20
is 0.02 mm smaller.
1. If the number on the old pinion is a plus (+), add it
to the old shim thickness. If it is a minus (-), sub-
tract it from the old shim thickness.
2. If the number on the new pinion is a plus (+), sub-
tract it from the number you got in step 1. If it is a
minus (-), add it to the step 1 number.
3. Select the shim that is closest (but not more than)
the final number you got from steps 1 and 2.
ETCHED MARK
eg: A1-1
Example 1:
Old shim: 2.00 mm thickness
Old pinion: +20 (0.02 mm)
New pinion: -10 (-0.01 mm)
2.00 + 0.02 + 0.01 = 2.03
Select the 2.03 mm (0.0799 in) new shim.
Example 2:
Old shim: 1.70 mm thickness
Old pinion: -10 (-0.01 mm)
New pinion: -20 (-0.02 mm)
1.70-0.01 +0.02 = 1.71
Select the 1.70 mm (0.0669 in) new shim.

Ring Gear Tooth Contact
Ring Gear Backlash
Adjustment
1) Correct Tooth Contact
2) Toe Contact
Use a thinner drive pinion shim (43 mm thrust
shim) to move the drive pinion away from the ring
gear.
3) Heel Contact
Use a thicker drive pinion shim (43 mm thrust
shim) to move the drive pinion toward the ring
gear.
4) Flank Contact
To move the ring gear away from the drive pin-
ion, use a thicker side bearing shim (79.5 mm
thrust shim) on the drive pinion side and a thinner
one on the ring gear side.
NOTE: Recheck backlash after replacing the side
bearing shims. If out of specification, adjust as
described under Toe Contact.
5) Face Contact
To move the ring gear toward the drive pinion,
use a thinner side bearing shim (79.5 mm thrust
shim) on the drive pinion side and a thicker one
on the ring gear side.
NOTE: Recheck backlash after replacing the side
bearing shims. If out of specification, adjust as
described under Heel Contact.
Adjustment
1. If the backlash exceeds the standard, correct by
decreasing the shim thickness on one side and
increasing the thickness of the other shim the same
amount.
NOTE:
• The total thickness of both shims must still equal
the total thickness of the original shims.
• If there is too much backlash, move the ring gear
toward the drive pinion. If there is not enough
backlash, move the ring gear away from the
drive pinion.
2. After adjustment, recheck backlash (see page,
).
Standard: 0.06 - 0.14 mm (0.002 - 0.006 in)
