• Check for the correct installation status prior to removal or disassembly. If matching marks are required, becertain 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 dam age, 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 tight-
ening 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 t he 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 tor que, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.

CAUTION:
Verify identification stamp of replacement frequency put in the lower part of gear carrier to determine
replacement for collapsible spacer when replacing front oil seal. Refer to "IDENTIFICATION STAMP OF
REPLACEMENT FREQUENCY OF FRONT OIL SEAL". If necessary collapsible spacer replacement,
remove final drive assembly and disassemble it to re place front oil seal and collapsible spacer. Refer
to RFD-16, "
Removal and Installation" and RFD-17, "Disassembly and Assembly".
NOTE:
The reuse of collapsible spacer is pr ohibited in principle. However, it is reusable on a one-time basis
only in cases when replacing front oil seal.
IDENTIFICATION STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL
 The diagonally shaded area in the figure shows stamping point for replacement frequency of front oil seal.
 The following table shows if collapsible spacer replacement is needed before replacing front oil seal.
When collapsible spacer replacement is required, disassemble
final drive assembly to replace collapsible spacer and front oil seal.
Refer to RFD-17, "
Disassembly and Assembly".
CAUTION:
Be sure to make a stamping after replacing front oil seal.
 After replacing front oil seal, make a stamping on the stamping point in accordance with the table below in order to identify replacement frequency.
CAUTION:
Stamping shall be made from left to right.
REMOVAL
1. Drain gear oil. Refer to RFD-9, "Changing Differential Gear Oil".
2. Make a judgment if a collapsible spacer replacement is required. Refer to "IDENTIFICATION STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL".
3. Remove center muffler with a power tool. Refer to EX-3
.
4. Remove rear wheel sensor. Refer to BRC-52
.
5. Remove drive shaft from final drive. Then suspend it by wire etc. Refer to RAX-10
.
6. Install attachment to side flange, and then pull out the side flange with the sliding hammer.
