2007 NISSAN 350Z check oil

RFD-40
REAR FINAL DRIVE ASSEMBLY
Revision: 2006 November2007 350Z
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

10. Apply anti-corrosion oil to the thread and seat of drive pinion
lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
11. Adjust to the drive pinion lock nut tightening torque and pinion
bearing 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.

After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.
12. Install differential case assembly. Refer to RFD-44, "
Differential Assembly" .
CAUTION:
Do not install rear cover yet.
13. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion
flange runout. Refer to RFD-40, "
Drive Gear Runout" , RFD-41, "Tooth Contact" , RFD-42, "Backlash" and
RFD-43, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
14. Check total preload torque. Refer to RFD-40, "
Total Preload Torque" .
15. Install rear cover. Refer toRFD-44, "
Differential Assembly" .
Differential Assembly
1. Install side gear thrust washer with the same thickness as the
ones installed prior to disassembly or reinstall the old ones on
the side gear.Tool number A: KV40104000 ( — )

Drive pinion lock nut tightening torque:
147 – 323 N·m (15 – 32 kg-m, 109 – 238 ft-lb)
Drive pinion bearing preload:
2.65 – 3.23 N·m (0.27 – 0.32 kg-m, 24 – 28 in-lb)

17. 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.
18. Check and adjust drive gear runout, tooth contact, drive gear to
drive pinion backlash, and total preload torque. Refer to RFD-
40, "Drive Gear Runout" , RFD-41, "Tooth Contact" , RFD-42,
"Backlash" and RFD-40, "Total Preload Torque" .
Recheck above items. Readjust the above description, if necessary.
19. Apply sealant to mating surface of rear cover.

Use Genuine Silicone RTV or equivalent. Refer to GI-45,
"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.
20. Install rear cover on gear carrier and tighten mounting bolts with
the specified torque. Refer to RFD-39, "
COMPONENTS" .
21. Install side flange with the following procedure.
NOTE:
Install the RH side flange, then install the LH side flange. If LH side flange is installed first, the RH side
flange comes out sometimes from the shock of installing the RH side flange.
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.Tool number : KV38100200 (J-26233)
