CAUTION
• The check balls are not reusable.
• Confirm the lengths of the shift check sleeves
and check springs before installing them. (A:
short, B: long)
• Be careful not to let the check balls drop into
the air breathing grooves in the clutch hous-
ing.
Install the two shift check sleeves, two check balls,
two check springs and two check ball plugs into posi-
tion.
>>K<< DIFFERENTIAL SIDE BEARING
ADJUSTMENT SHIM INSTALLATION
CAUTION
Do not use more than two shims.
Install the appropriate adjustment shims that will pro-
vide the differential side bearing with a preload within
the standard value range.
Standard value: 0.15
− 0.21 mm

Adjustment shim
1. Selecting appropriate shims
(1) Measure the distance between the end
surface and the adjustment shim fitting surface
on the transmission case (L1). Next, measure
the distance between the clutch housing end
surface and the differential side bearing end
surface (L2).
(2) Use the following equation to calculate the
clearance L between the transmission case
and the differential side bearing outer race:
L = L1
− L2
(3) Select an adjustment shim (or a set of
adjustment shims) with a thickness of L plus
0.15 mm to 0.21 mm (standard value range).

2. Measuring distances L1 and L2
(1) Install the special tool Adjustment adapter
(MB991969) into the differential side rear
bearing hole in the transmission case. Use the
following equation to calculate the distance L1
(see the illustration above):
L1 = 25.00 (height of MB991969)
− measure-
ment "a"
(2) Attach the outer race onto the differential side
bearing on the final gear side, and rotate the
final gear set five or more times by hand while
holding the outer race down lightly to keep it
from tilting.
NOTE: Rotating the final gear in this way will
help the bearing rollers to seat completely
against their races.

Pick tester
Height gauge
CAUTION
Before making the following measurement, make
sure to confirm that the outer race is level by
measuring the height of the outer race surface at
three different points.
(3) Use a height gauge to measure the distance
between the differential side bearing outer
race and the transmission mounting surface of
the clutch housing (L2).

1. Heat the transmission case to about 100
°C
(maximum temperature: 120
°C).
