Oil Pump
The oil pump is not a serviceable component. Replace the pump as an assembly if the gear teeth are worn, or if the pump has be-
come damaged.
Bearings and Seals
The transfer case seals should be replaced during overhaul. Use new seals in the oil pump, input gear bearing retainer, front case,
and extension housing. Also replace the yoke seal washer and detent plug O-ring.
FRONT OUTPUT SHAFT BEARING AND SEAL REPLACEMENT
1.
Remove the snap ring securing the front bearing in the front case (Figure 5-60).
2.
Tap the old bearing out rearward of the front case with plastic or raw hide mallet.
3.
Install a new bearing with tool handle J–8092, and the installer tool J–33833 (Figure 5-61).
4.
Lubricate the new bearing with Dexron III.
5.
Install the new shaft seal with seal installer J–38869 (Figure 5-62). Then lubricate the seal lip with Dexron III.
6.
Remove the front output shaft rear bearing from the rear case as follows:
a.
Clamp the rear case to a bench with wood blocks, and C-clamps.
b.
Pull the bearing using a slide hammer, adapter J–2619-01, and puller J–26369 (Figure 5-63).
c.
Install a new bearing with tool handle J–8092, and installer J–33832 (Figure 5-64). The rear bearing bore is chamfered at
the top. Install the bearing so it is flush with the chamfer lower edge.
CAUTION: Do not bottom the bearing in the bore. This will block the oil feed hole in the rear case bearing bore.
