Set dummy cover shims to the right and left side bearing adjusting shims.
b.
Temporarily tighten dummy cover to gear carrier.
c.
Position dummy cover spacers to dummy cover.
d.
Tighten rear cover mounting bolts to the specified torque. Refer to
.
e.
Tighten dummy cover spacer mounting bolts evenly to the specified torque.

INSPECTION AFTER DISASSEMBLY
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).
