ADJUSTMENT AND SELECTION OF ADJUSTING WASHERS
Differential Side Gear Clearance
Assemble the differential parts if they are disassembled. Refer to FFD-28, "Differential Assembly" .
1. Place differential case straight up so that side gear to be mea-
sured comes upward.
2. Using feeler gauge, measure the clearance between side gear
back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.
CAUTION:
To prevent side gear from tilting, insert feeler gauges with
the same thickness from both sides.
3. If the back clearance is outside the specification, use a thicker/
thinner side gear thrust washer to adjust. Refer to FFD-32, "
Side
Gear Thrust Washer" .
CAUTION:
Select a side gear thrust washer for right and left individually.
Pinion Gear Height
Drive gear and pinions are supplied in matched sets only.
Matching numbers on both pinion and drive gear are etched for
verification. If a new gear set is being used, verify the numbers
of each pinion gear and drive gear before proceeding with
assembly.
The mounting distance from the center line of the drive gear to the back face of the pinion gear for the
M205 final drive is 103.5 mm (4.0748 inches).
On the button end of each pinion, there is etched a plus (+) number, a minus (-) number, or a zero (0),
which indicates the best running position for each particular gear set. This dimension is controlled by a
selective shim between the inner pinion bearing race and pinion gear.
For example: If a pinion is etched m+8 (+3), it would require 0.08 mm (0.003 inch) less shim than a pinion
etched “0”. This means decreasing shim thickness; increases the mounting distance of the pinion to 103.6
mm (4.0778 inches). If a pinion is etched m+8 (-3), it would require adding 0.08mm (0.003 inch) more to
the shim than would be required if the pinion were etched “0”. By adding 0.08 mm (0.003 inch), the mount-

When the back clearance is large:
Use a thicker thrust washer.
When the back clearance is small:
Use a thinner thrust washer.

ing indicated.
