DRAINING
1. Stop engine.
2. Remove drain plug and drain gear oil.
3. Set a gasket on drain plug and install it to final drive assembly
and tighten to the specified torque. Refer to RFD-19, "
COMPO-
NENTS" (R200 2-pinion) or RFD-39, "COMPONENTS" (R200V
LSD).
CAUTION:
Do not reuse gasket.
FILLING
1. Remove filler plug. Fill with new gear oil until oil level reaches
the specified level near filler plug mounting hole.
2. After refilling oil, check oil level. Set a gasket to filler plug, then
install it to final drive assembly. Refer to RFD-19, "
COMPO-
NENTS" (R200 2-pinion) or RFD-39, "COMPONENTS" (R200V
LSD).
CAUTION:
Do not reuse gasket.
Checking Differential Gear OilNDS0000F
OIL LEAKAGE AND OIL LEVEL

Make sure that oil is not leaking from final drive assembly or around it.

Check oil level from filler plug mounting hole as shown in the fig-
ure.
CAUTION:
Do not start engine while checking oil level.

Set a gasket on filler plug and install it on final drive assembly.
Refer to RFD-19, "
COMPONENTS" (R200 2-pinion) or RFD-39,

Removal and InstallationNDS0000G
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-17, "
Removal and Installation" , RFD-19, "Disassembly and Assembly (R200 2-
pinion)" and/or RFD-39, "Disassembly and Assembly (R200V LSD)" .
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-19, "
Disassembly and Assembly (R200 2-
pinion)" or RFD-39, "Disassembly and Assembly (R200V LSD)"
.
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 rear wheel sensor. Refer to BRC-34, "
WHEEL SENSORS" (ABS),BRC-73, "WHEEL SEN-
SORS" (TCS/ABS) or BRC-128, "WHEEL SENSORS" (VDC/TCS/ABS).
4. Remove drive shaft from final drive. Then suspend it by wire etc. Refer to RAX-10, "
Removal and Installa-
tion" .
5. Install attachment to side flange, and then pull out the side
flange with the sliding hammer.
NOTE:
6. Remove propeller shaft. Refer to PR-6, "
Removal and Installation" .
7. Measure the total preload with the preload gauge.
NOTE:
Record the preload measurement.
8. Remove drive pinion lock nut using the flange wrench.
9. Put matching mark on the end of the drive pinion. The matching
mark should be in line with the matching mark A on companion
flange.
CAUTION:
For matching mark, use paint. Do not damage drive pinion.
NOTE:
The matching mark A on the final drive companion flange indi-
cates the maximum vertical runout position.Tool number A: KV40104100 ( — )

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, "
