●

Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of oil seal.

17. Check and adjust drive gear runout, tooth contact, drive gear to

drive pinion backlash, and total preload torque. Refer to 

RFD-

19, "Drive Gear Runout"

 , 

RFD-20, "Tooth Contact"

 , 

RFD-21,

"Backlash"

 , 

RFD-19, "Total Preload Torque"

 .

Recheck above items. Readjust the above description, if necessary.

18. Apply sealant to mating surface of rear cover.

●

Use Genuine Silicone RTV or equivalent. Refer to 

GI-47,

"RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS"

 .

CAUTION:

Remove old sealant adhering to mounting surfaces. Also
remove any moisture, oil, or foreign material adhering to
application and mounting surfaces.

19. Install rear cover on gear carrier and tighten mounting bolts with

the specified torque. Refer to 

RFD-18, "COMPONENTS"

 .

20. Install side flange with the following procedure.

a.

Attach the protector to side oil seal.

b.

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

c.

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 which seems to affect the whole final drive.

d.

Confirm that the dimension of the side flange installation (Mea-
surement A) in the figure comes into the following.
