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 toFFD-9, "
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 toFFD-15, "
Removal and Installation"andFFD-17, "Disassembly and Assembly".
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
lThe diagonally shaded area in the figure shows stamping point
for replacement frequency of front oil seal.
lThe 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 toFFD-17, "
Disassembly and Assembly".
CAUTION:
Be sure to make a stamping after replacing front oil seal.
lAfter 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 toFFD-8, "DRAINING".
2. Make a judgment if a collapsible spacer replacement is required. Refer toFFD-9, "
IDENTIFICATION
STAMP OF REPLACEMENT FREQUENCY OF FRONT OIL SEAL".
3. Remove the front wheels and tires using power tool.
4. Without disassembling the hydraulic lines, remove the caliper torque member bolts using power tool.
