[REAR FINAL DRIVE: R200]

FRONT OIL SEAL

Install attachment (A) [SST: KV40104100 (

—

)] to side

flange, and then pull out the side flange with the sliding hammer
(B) [SST: ST36230000 (J-25840-A)].
NOTE:
Circular clip installation position: Final drive side

Remove rear propeller shaft. Refer to

DLN-81, "Exploded View"

Measure the total preload with the preload gauge (A) [SST:
ST3127S000 (J-25765-A)].
NOTE:
Record the preload measurement.

Put matching mark (B) on the end of the drive pinion. The
matching mark (B) should be in line with the matching mark (A)
on companion flange (1).

CAUTION:

For matching mark, use paint. Never damage companion
flange and drive pinion.
NOTE:
The matching mark (A) on the final drive companion flange (1)
indicates the maximum vertical runout position.

10. Remove drive pinion lock nut using the flange wrench.

11. Remove companion flange using pullers.

12. Remove front oil seal using the puller (A) [SST: KV381054S0 (J-

34286)].

INSTALLATION

Apply multi-purpose grease to front oil seal lips.

Install front oil seal using the drift (A) [SST: ST30720000 (J-
25405)] as shown in figure.

CAUTION:

• Never reuse oil seal.
• Never incline oil seal when installing.

Align the matching mark (B) of drive pinion with the matching
mark (A) of companion flange (1), and then install the compan-
ion flange (1).

FRONT OIL SEAL

Apply anti-corrosion oil to the thread and seat of new drive pin-
ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.

CAUTION:

Never reuse drive pinion lock nut.

Tighten drive pinion lock nut within the limits of specified torque
so as to keep the pinion bearing preload within a standard val-
ues.

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. Never
loosen drive pinion lock nut to adjust the preload torque.

Set a dial indicator (A) vertically to the tip of the drive pinion.

Rotate drive pinion to check for runout.

• If the runout value is still outside of the limit after the phase

has been changed, possible causes are an assembly malfunc-
tion of drive pinion and pinion bearing and malfunction of pin-
ion bearing. Check for these items and repair if necessary.

Make a stamping for identification of front oil seal replacement
frequency. Refer to “Identification stamp of replacement frequency of front oil seal”.

CAUTION:

Make a stamping after replacing front oil seal.

Install rear propeller shaft. Refer to

DLN-81, "Exploded View"

10. Install side flange with the following procedure.
a.

Attach the protector [SST: KV38107900 (J-39352)] to side oil
seal.

After the side flange is inserted and the serrated part of side
gear has engaged the serrated part of flange, remove the pro-
tector.

Put a suitable drift on the center of side flange, then drive it until
sound changes.
NOTE:
When installation is completed, driving sound of the side flange
turns into a sound that seems to affect the whole final drive.
