Removal and Installation: Installation
- Apply multi-purpose grease to front oil seal lips.
- Install front oil seal using the drift (A) [SST: ST30720000 (J-25405)] as shown in figure, below.CAUTION:
- Never reuse oil seal.
- Never incline oil seal when installing.
- Align the matching mark (B) of drive pinion with the matching mark (A) of companion flange (1), and then install the companion flange.
- Apply anti-corrosion oil to the thread and seat of new drive pinion lock nut, and temporarily tighten drive pinion lock nut to drive pinion, using flange wrench (commercial service tool).
A
: Preload gauge [SST: ST3127S000 (J-25765-A)]
CAUTION: Never reuse drive pinion lock nut. - Tighten drive pinion lock nut within the limits of specified torque so as to keep the pinion bearing preload within a standard values, using preload gauge [SST: ST3127S000 (J-25765-A)].
Total preload torque
: A value that add 0.1 - 0.4 N.m (0.01 - 0.04 kg-m, 1 - 3 in-lb) to the measured value before removing.
CAUTION:- Adjust to the lower limit of the drive pinion lock nut tightening torque first.
- If the preload torque exceeds the specified value, replace collapsible spacer and tighten it again to adjust. Never loosen drive pinion lock nut to adjust the preload torque.
- Make a stamping for identification of front oil seal replacement frequency. Refer to "Identification Stamp Of Replacement Frequency Of Front Oil Seal".CAUTION: Make a stamping after replacing front oil seal.
- Install final drive assembly. Refer to Removal and Installation .
- Refill gear oil to the final drive and check oil level. Refer to Refilling .
- Check the final drive for oil leakage. Refer to Inspection .
