FRONT OIL SEAL
Revision: 2006 January2006 M35/M45
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" and FFD-15, "Disassembly 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 FA X - 11 , "
Removal and Installation" .
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" . Tool number A: ST33400001 (J-26082)
