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).

Oil Seal 

• Whenever disassembled, replace.
• If wear, deterioration of elasticity (sealing force lips), or damage is detected on the lips, replace them.

Companion Flange 

• Clean up the disassembled parts.
• If any chipped mark [about 0.1 mm, (0.004 in)] or other damage on the contact sides of the lips of the companion flange is found, replace.
