Removal and InstallationNDS000F5
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 RFD-10, "
IDENTIFICATION
STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL" . If necessary collapsible spacer
replacement, remove final drive assembly and disassemble it to replace front oil seal and collapsible
spacer. Refer to RFD-16, "

NOTE:
The reuse of collapsible spacer is prohibited 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-18, "
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, "DRAINING" .
2. Make a judgment if a collapsible spacer replacement is required. Refer to RFD-10, "
IDENTIFICATION
STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL" .
3. Remove center muffler with a power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
4. Remove rear wheel sensor. Refer to BRC-57, "
WHEEL SENSOR" .
5. Remove drive shaft from final drive. Then suspend it by wire etc. Refer to RAX-8, "

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.
