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.

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 tighte n it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
6. Make a stamping for identificati on of front oil seal replacement
frequency. Refer to "IDENTIFICATION STAMP OF REPLACE-
MENT FREQUENCY OF FRONT OIL SEAL".
CAUTION:
Be sure to make a stamping after replacing front oil seal.
