PRECAUTIONS
Revision: 2006 November2007 350Z
PRECAUTIONSPFP:00001
Service Notice or PrecautionsNDS00009
Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.
Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
Clean and flush the parts sufficiently and blow-dry them.
Be careful not to damage sliding surfaces and mating surfaces.
When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
Always use shop paper for cleaning the inside of components.
Avoid using cotton gloves or shop rags to prevent entering of lint.
During assembly, observe the specified tightening torque, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.

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.

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, "

6. Set a suitable jack to rear final drive assembly.
CAUTION:
Do not place a suitable jack on the rear cover (aluminum
case).
7. Remove the mounting bolts and nuts connecting to the suspen-
sion member, and remove rear final drive assembly.
CAUTION:
Secure rear final drive assembly to a suitable jack while
removing it.
INSTALLATION
Note the following, and installation is in the reverse order of removal.
Refer to RFD-19, "COMPONENTS" (R200 2-pinion) or RFD-39, "COMPONENTS" (R200V LSD) about
each tightening torque.
When installing breather hoses, refer to the figure.
CAUTION:
Make sure there are no pinched or restricted areas on the
breather hose caused by bending or winding when install-
ing it.
–For installation, the vehicle side end shall be inserted to suspen-
sion member. Install metal connector side of this hose to rear
cover by inserting it with aiming painted marking to the front of
vehicle.
When oil leaks while removing final drive assembly, check oil
level after the installation. Refer to RFD-9, "
Checking Differential
Gear Oil" .

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-24, "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-35, "
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-20, "
Drive Gear Runout" , RFD-21, "Tooth Contact" , RFD-22, "Backlash" and
RFD-23, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
14. Check total preload torque. Refer to RFD-20, "
Total Preload Torque" .
15. Install rear cover. Refer to RFD-35, "

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 RFD-
20, "Drive Gear Runout" , RFD-21, "Tooth Contact" , RFD-22,
"Backlash" 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 GI-45,
"Recommended Chemical Products and Sealants" .
CAUTION:
