If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height [dimension (X)].
• If the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.
• If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.
BACKLASH
Before inspection and adjustment, drain gear oil.
1.
Remove rear cover. Refer to
.
2.
Fit a dial indicator to the drive gear face to measure the back-
lash.
• If the backlash is outside of the specified value, change the
thickness of side bearing adjusting washer.

DRIVE GEAR AND DRIVE PINION
• Clean up the disassembled parts.
• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive
gear and drive pinion as a set.
BEARING
• Clean up the disassembled parts.
• If any chipped (by friction), pitted, worn, rusted or scratched marks, or unusual noise from the bearing is
observed, replace as a bearing assembly (as a new set).
SIDE GEAR AND PINION MATE GEAR
• Clean up the disassembled parts.
• If any cracks or damage on the surface of the tooth is found, replace.
• If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
SIDE GEAR THRUST WASHER AND PINION MATE THRUST WASHER
• Clean up the disassembled parts.
• If it is chipped (by friction), damaged, or unusually worn, replace.
OIL SEAL
• Whenever disassembled, replace.
• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
DIFFERENTIAL CASE
• Clean up the disassembled parts.
• If any wear or crack on the contact sides of the differential case is found, replace.
COMPANION FLANGE
• Clean up the disassembled parts.
