fig 8.
1.
Install both vertical shaft roller bearings [7
-
17] into the gear case [7
-
1].
2.
Install both vertical shaft lower bearing cups [7
-
15], and shims [7
-

7.
Check the pinion gear height (optimum .025) (see
“
Lower Pinion Height Measurement
”)
(Fig. 8).
8.
Adjust lower cup shims [7
-
16] to obtain .025.
9.
Repeat the same procedure on the rear vertical shaft (short) [7
-
4].
10.
Remove both long [7
-
3] and short [7
-
4] vertical shafts and pinion gears [7
-
21].
11.

-
18], and prop gear bearing cup [7
-
19] into the gear
case [7
-
1].
12.
Install the prop gear bearing cone [7
-
20] onto the prop gear [7
-
21].
13.
Install the prop gear [7
-
21] with bearing [7
-
20] into the gear case. (The prop shaft bushing [7
-
22], used
only with the 01
-
8244 and 01
-
8248 gear sets, must be installed into the prop gear at this time).
14.
Re
-
install the vertical shaft components described above, torque pinion flange nut [7
-
27]
to 150 ft/lbs.
15.
Install rear prop gear [7
-
25], then bearing carrier bearing cone [7
-
30] onto the prop shaft [7
-
24].
16.
Install the prop shaft [7
-
24] with bearing [7
-
30] into the gear case.
17.
Install the prop shaft seals [7
-
32], and bearing carrier bearing cup [7
-
31] into the bearing
carrier [7
-
33].
18.
Temporarily install the bearing carrier [7
-
33] into the gear housing [7
-
1].
19.
Install bearing carrier [7
-
33], tab washer [7
-
36], and retainer nut [7
-
37], torque to
20 in/lbs rolling.
20.
Rotate the vertical shaft at least 3 turns and check the front prop gear backlash
(optimum .012
-
.015).
21.
Adjust the thickness of the prop gear bearing cup shims [7
-
18] to obtain the correct
backlash readings.
22.
Remove retainer nut [7
-
37], bearing carrier [7
-
33], prop shaft [7
-
24].
23.
Remove front pinion nut [7
-
27], pinion gear [7
-
21], and vertical shaft (long) [7
-
3].
24.
Leave front prop gear in case.
25.
Install rear vertical shaft (short) [7
-
4], vertical preload tab washer 7
-
7], pinion preload nut [7
-
9] (tighten
to 8
-
9 in/lbs rolling torque).
26.
Install rear pinion gear [7
-
25], pinion flange nut [7
-
27] torque to 150 ft/lbs.
27.
Install prop shaft with shim [7
-
23] between front prop gear [7
-
21] and prop shaft spline
seat (shoulder).
28.
Install bearing carrier [7
-
33], tab washer [7
-
36], and retainer nut [7
-
