PRECAUTIONS
PRECAUTIONSPFP:00001
Service Notice or PrecautionsEDS001YY
Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.
Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
Clean and flush the parts sufficiently and blow-dry them.
Be careful not to damage sliding surfaces and mating surfaces.
When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
Always use shop paper for cleaning the inside of components.
Avoid using cotton gloves or shop rags to prevent entering of lint.
During assembly, observe the specified tightening torque, and apply new differential oil, petroleum jelly, or
multi-purpose grease as specified for each vehicle, if necessary.
