G. Input Shaft Assembly
Refer to Page PM2 and Page PB6
1.
Place the direct drive gear (Item 22), with bearings
(Item 11) and spacer (Item 13) previously installed,
in the housing against the back wall. The gear will
mesh with the gear on the intermediate shaft and
rest against the side wall of the case housing.
2.
Insert the direct drive gear clutch (Item 10) in the
direct drive gear (Item 22).
3.
Insert the non-threaded end of the input shaft (Item
21) into the case housing from the front of the case.
The shaft should project into the case between 3/4"
and 2" and the shaft may rest against the bottom of
the input bearing bore of the housing.
4.
Slip the underdrive pinion gear (Item 19), with
projecting face toward the shaft, onto the end of the
shaft.
5.
Slide input shaft through the underdrive pinion gear
and into the direct drive sliding clutch (Item 10).
When splines come into contact with the pinion gear,
align splines, continue shaft installation, align splines
with splines in underdrive gear sliding clutch (See
Fig. 30), and again continue sliding shaft into place
through the bearings (Item 11) and gear (Item 22).
Slip spacer washer (Item 23) (. 06 thick) over rear
end of input shaft.
6.
Slide input shaft front (Item 18) and rear (Item 24)
bearings onto the input shaft. Tap into the case
housing bores and into place on the shaft with a
suitable driver.
7.
Push the input shaft as far to the rear of the case
housing as it will go. Push the underdrive pinion
gear toward the front of the case.
8.
Install the split retaining ring (Item 20) in place in the
half round groove that should now be exposed (See
Fig. 31).
9
Install the input seal carrier gasket in place on the
front of the case housing and install the input seal
carrier seal assembly in place. Permatex the
mounting screws and tighten to the specified torque
(See Fig. 32).
10. Apply Lubriplate to the seal area and the splines of
the input yoke. Install the yoke on the front of the
input shaft. Put yoke retaining washer (Item 2) onto
the shaft with the side that faces the input yoke
lightly coated with Permatex. Install the input yoke
retaining nut (Item 1) and tighten to specifications.
