PRECAUTIONS
Revision: 2007 April2007 M35/M45
PRECAUTIONSPFP:00001
Service Notice or PrecautionsNDS000EY

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 gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.

4. Apply anti-corrosion oil to the thread and seat of new drive pin-
ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
5. Tighten to drive pinion lock nut, while adjust total preload torque.
CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Do not
loosen drive pinion lock nut to adjust the preload torque.
6. Make a stamping for identification of front oil seal replacement
frequency. Refer to RFD-10, "
