Assembling the Transmission Gear Box Assembly (continued)
37. Insert the wave washer (item 3 in Figure 26 ) and neutral spur gear assembly
(5) into the transmission housing assembly (23). Make sure that the traction
selector shaft (item 19 in
Figure 25 ) is engaged in shift selection neutral spur
gear (item 5 in Figure 26 ).
38. Apply a coat of grease to ORB plug (item 8 in Figure 25 ) and install the
detent ball (10), detent spring (9) and ORB plug (8) into the transmission
housing (26).
39. Torque tighten the ORB plug (8) from 3.6 to 4.7 N·m (32 to 42 in-lb) .
40. Use a press and insert the ball bearing (item 25 in Figure 25 ) into the
transmission cover (23). Install the retaining ring (5) and oil seal (6) into
the transmission cover (23).
41. Ensure that the oil seal lip is orientated toward the center of the transmission
housing. Press the seal into the transmission housing bore so that the seal
is flush to the edge of the transmission housing.
42. Install the oil seal (item 14 in Figure 25 ) into the transmission cover (23).
43. Ensure that the oil seal lip is orientated toward the center of the transmission
housing. Press the seal into the transmission housing bore so that the seal
is flush to the edge of the transmission housing.
44. If removed, insert the 2 dowel pins (item 17 in Figure 25 ) into the transmission
housing assembly (26).
45. Install the new transmission gasket (item 22 in Figure 25 ) and transmission
cover assembly (23) onto the transmission housing (26) by aligning the holes.
Secure the transmission cover assembly with 12 bolts (24) and torque tighten
to
1.7 to 4.5 N∙m (15 to 40 in-lb) . Use an alternation pattern and torque
tighten the bolts to 9.6 to 10.7 N∙m (85 to 95 in-lb) .
Note: Transmission gear box assembly (26) must be leak free. Apply a
pressure of 2.5 PSI for 30 seconds without dropping more than 1 PSI.
46. Fill the transmission gear box assembly (26) with 1 lb (16 oz) of Mobil AFT
D/M oil.
47. Apply a coat of grease to the O-rings and insert onto the hollow hex plugs.
Install the hollow hex plug (item 27 in Figure 25 ) into the transmission gear
box assembly (26).
48. Torque tighten the hollow hex plug (27) from 12.4 to 14.7 N·m (110 to 130
in-lb) .
49. Apply a coat of grease to the adapter-vent (29). Install the adapter-vent (29)
into the transmission gear box assembly (26).
50. Torque tighten the adapter-vent (29) from 12.4 to 14.7 N·m (110 to 130 in-lb) .
51. Install the breather-vent (30) into the adapter-vent (29). Tighten the
breather-vent (30) until the gasket contacts the adapter-vent and then tighten
an additional 75º to 85º turn.
