General Instructions for Disassembly
Important:
Read this section before starting the detailed disassembly procedures.
It is assumed in the detailed disassembly instructions that the transmission has been removed from the chassis, the lubricant has
been drained, the parking brake removed, if so equipped, and both universal joint companion flanges have been removed.
Follow each procedure closely in each section, making use of both the text and pictures. Use certain precautions, as listed below,
during disassembly.
Cleanliness
•
Provide a clean place to work. It is important that no dirt or foreign material enters the unit during repairs. The outside
of the unit should be carefully cleaned before starting the disassembly. Dirt is abrasive and can damage highly polished
parts such as bearings, sleeves, and bushings.
Bearings
•
Carefully wash and re-lubricate all bearings as removed and protectively wrap until ready for use. Remove all bearings
with pullers designed for this purpose. Do not remove bearings with hammer and punch.
When Driving
•
Apply force to shafts, bearings, and housings with restraint. Movement of some parts is restricted. Do not apply force
after the part being driven stops solidly. Use soft hammers, soft bars, and mauls for all disassembly work.
Snap Rings
•
Remove snap rings with pliers designed for this purpose. Rings removed in this manner may be reused.
Bearing removed with
chisel, damaged outer race.
Bearing removed with punch,
damaged shield.
