Infiniti G35 (V35). Manual — part 703
RFD-38
REAR FINAL DRIVE ASSEMBLY
16. Using the drift, drive side oil seals until it becomes flush with the
case end.
CAUTION:
●
Do not reuse oil seal.
●
When installing, do not incline oil seal.
●
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
and
RFD-20, "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
"Recommended Chemical Products and Sealants"
.
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
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.

REAR FINAL DRIVE ASSEMBLY
ASSEMBLY INSPECTION AND ADJUSTMENT
●
Before inspection and adjustment, drain gear oil.
Total Preload Torque
1.
Secure final drive assembly onto an attachment.
2.
Remove side flanges.
3.
Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4.
Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
5.
Measure total preload with the preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque
●
If measured value is out of the specification, disassemble it to
check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
Drive Gear Runout
1.
Remove rear cover. Refer to
RFD-44, "Differential Assembly"
2.
Fit a dial indicator to the drive gear back face.
3.
Rotate the drive gear to measure runout.
●
If the runout is outside of the repair limit, check drive gear
assembly condition; foreign material may be caught between
drive gear and differential case, or differential case or drive gear
may be deformed, etc.
CAUTION:
Replace drive gear and drive pinion gear as a set.
Tool number
: KV38100800 (J-25604-01)
Tool number
: ST3127S000 (J-25765-A)
Total preload torque:
2.85 – 3.75 N·m (0.29 – 0.38 kg-m, 26 – 33 in-lb)
PDIA0635E
When the preload torque is large
On pinion bearings:
Replace the collapsible spacer.
On side bearings:
Use thinner side bearing adjusting washers by the same amount to
each side. Refer to
RFD-60, "Side Bearing Adjusting Washer"
When the preload is small
On pinion bearings:
Tighten the drive pinion lock nut.
On side bearings:
Use thicker side bearing adjusting washers by the same amount to
each side. Refer to
RFD-60, "Side Bearing Adjusting Washer"
Runout limit:
0.05 mm (0.0020 in) or less

Tooth Contact
1.
Remove rear cover. Refer to
RFD-44, "Differential Assembly"
2.
Apply red lead to drive gear.
CAUTION:
Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on drive gear.
3.
Rotate drive gear back and forth several times, check drive pin-
ion gear to drive gear tooth contact.
CAUTION:
Check tooth contact on drive side and reverse side.
