Special Instructions

None

Special Tools

• See Tool Information (see Table 6) • Item T12: Input bearing driver • Toolmaker’s dye

Procedure -

1. If necessary, install the bushing in the back of the input shaft.

2. From the front, engage the input shaft spline teeth into the main drive gear.

Note: The current design input shaft spline teeth have noticeable clearance to the main drive gear internal spline teeth. This is normal.

3. Install the snap ring in the main drive gear inside groove.

4. With the bearing external snap ring to the outside, position the bearing on the input shaft.

5. Install the input shaft bearing over the input shaft. Use a flanged-end bearing driver which contacts both the bearing inner race and outer race. Drive the bearing until it contacts the front case.

6. Install the input shaft retaining snap ring.

Note: Do not replace the small rubber lip seal. It is used only to prevent leakage during shipping.

7. Install the front bearing cover and torque the six capscrews to specifications.
