Revision: 2006 July 2007 FX35/FX45
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

FRONT OIL SEAL
Revision: 2006 July 2007 FX35/FX45
INSTALLATION
1. Apply multi-purpose grease to front oil seal lips.
2. Using the drifts, install front oil seal as shown in figure.
CAUTION:

Do not reuse oil seal.

When installing, do not incline oil seal.
3. Align the matching mark (B) of drive pinion with the matching mark (A) of companion flange, and then install the companion
flange (1).
4. 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:
Do not reuse drive pinion lock nut.
5. Tighten to drive pinion lock nut, while adjust total preload torque.
CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.

If measured value is out of the specification, remove final
drive assembly and disassemble drive pinion parts to check
and adjust each part. Refer to FFD-13, "
Removal and Installa-
tion (VQ35DE Models)" ,FFD-15, "Removal and Installation (VK45DE Models)" and FFD-17, "Disas-
sembly and Assembly" .
6. Install front propeller shaft. Refer to PR-5, "
Removal and Installation" .
7. Install side shaft assembly.
8. Install front drive shaft both. Refer to FAX-15, "
Removal and Installation (Left Side)" , FAX-16, "Removal
and Installation (Right Side)" .
9. Refill gear oil to the final drive and check oil level. Refer to FFD-8, "
FILLING" .
10. Check the final drive for oil leakage. Refer to FFD-8, "
OIL LEAKAGE AND OIL LEVEL" .

2. Temporarily install pinion height adjusting washer (1).
When hypoid gear set has been replaced

Select pinion height adjusting washer. Refer to FFD-31, "Pin-
ion Gear Height" .
When hypoid gear set has been reused

Temporarily install the removed pinion height adjusting
washer or same thickness washer to drive pinion.
3. Install selected pinion height adjusting washer (2) to drive pin- ion. Press pinion rear bearing inner race (1) to it, using drift.
CAUTION:

Pay attention to the direction of pinion height adjusting
washer. (Assemble as shown in the figure.)

Do not reuse pinion rear bearing inner race.
4. Temporarily assemble removed drive pinion adjusting washer and drive pinion bearing adjusting washer or same thickness
them to drive pinion.
