)] to gear car-
rier.
a.
Set dummy cover shims [SST: KV38108630 (
—
)] to the right and left side bearing adjusting
shims.
b.
Temporarily tighten dummy cover [SST: KV38108610 (
—
)] to gear carrier.
c.
Position dummy cover spacers [SST: KV38108621 (
—
)] to dummy cover [SST: KV38108610
(
—
)].
d.

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).

: 5.9 N·m (0.6 kg-m, 52 in-lb)
Standard
Backlash
: Refer to
.
When the backlash is large:
Make drive gear back adjusting shims thicker, and drive
gear front adjusting shims thinner. For selecting ad-
justing shim, refer to the latest parts information.
When the backlash is small:
Make drive gear back adjusting shims thinner, and
drive gear front adjusting shims thicker. For selecting
