Install the pinion assembly with the
selected spacer above and measure the circumference backlash on
pinion.
(Measuring diameter, backlash and
permissible deviations for measurement on pinion, see table
below).
If the result is out of permissible range,
change the spacer thickness S2, then start again with the step
8~12).
Tips For Spacer Adjustment For Hypoid Gear Backlash And
Contact Pattern
Item
|
Symptom
|
Remedy
|
Backlash
|
When more than the standard value (0.16 ~
0.21mm)
|
Adjust backlash by installing the spacer S1 using
a thinner one and gradually installing a thicker
one.
|
When less than the standard value (0.16
~0.21mm)
|
Adjust backlash by installing the spacer S1 using
a thicker one and gradually installing a thinner
one.

Item
|
Symptom
|
Remedy
|
Hypoid gear tooth contact
pattern
|
|
| - |
Both drive and coast
surfaces are in center in lateral direction and
slightly incline to TOE side in vertical
direction | |
| • |
If the pattern deviates from the
standard, adjust it by following
procedure | |
|
|
| • |
The drive surface inclines to
TOE and TOP and the coast surface inclines to HEEL and
TOP | The tooth contact pattern can be moved to the
arrow direction by installing the spacer S2 using a thinner
one and gradually installing a thicker
one.
|
|
| 19. |
Remove the pinion assembly. With the spacer
S3 and transfer cover mounted, combined preload torque for the
hypoid gear shaft assembly and transfer gear (measured on transfer
gear) should be 2.7 to 3.8Nm. The spacer S3 has to be changed, if
the preload torque is not within the permissible
range. |
| 20. |
Tighten the pinion assembly mounting bolts
(B-7EA) to install the pinion assembly(A).
Tightening
torque :
37~40 Nm(3.7~4.0 kgf.m, 14.5~21.7
lb-ft)
|
| 1. |
Before installing the pinion
assembly, check the pinion O-ring and apply the oil to
the O-ring. |
| 2. |
To make the installation of the
pinion to the transfer easier, tap the pinion using a
plastic hammer after aligning the bolt
holes. | |
| |
