ASSEMBLY
26. If necessary, select the proper reaction plate to achieve specifications:
Underdrive Reaction Plate Thickness:
Figure 24 Install OD Clutch Pack
1 - OVERDRIVE CLUTCH PACK
27. Install the OD clutch pack (four frictions/three steels) (1) (Figure 24).
Figure 25 Install Waved Snap Ring
28. Install OD pressure plate waved snap ring (1) (Figure 25).
Figure 26 OD/Reverse Pressure Plate
29. Install the OD/Reverse pressure plate (1) with large step down (towards OD clutch pack) (2) (Figure 26).
Figure 27 Overdrive Clutch Assembly
30. Refer to the exploded view as necessary when performing the following steps (Figure 27).
Figure 28 Install Flat Snap Ring
31. Install OD pressure plate flat snap ring (3) (Figure 28).
Figure 29 Measure OD Clutch Pack Clearance
32. Measure OD clutch pack clearance. Set up dial indicator (1) (Figure 29) on top of the OD/Reverse pressure plate.
33. Zero dial indicator and apply 30 psi (206 kPa) air pressure to the overdrive clutch hose on Tool 8391. Measure and record OD clutch pack measurement in four places, 90� apart.
34. Take average of four measurements and compare with OD clutch pack clearance specification. The overdrive (OD) clutch pack clearance is 1.07-3.25 mm (0.042-0.128 in.).
If not within specifications, the clutch is not assembled properly. There is no adjustment for the OD clutch clearance.
Figure 30 Install Reverse Clutch Pack
35. Install reverse clutch pack (two frictions/one steel) (1, 2) (Figure 30).
Figure 31 Install Reaction Plate
1 - REVERSE CLUTCH REACTION PLATE (FLAT SIDE DOWN)
36. Install reverse clutch reaction plate with the flat side down towards reverse clutch (Figure 31).
Figure 32 Reverse Clutch Assembly
37. Refer to the exploded view as necessary when performing the following steps (Figure 32).
Figure 33 Install Reverse Clutch Snap Ring
38. Tap reaction plate (3) (Figure 33) down to allow installation of the reverse clutch snap ring (1) Install reverse clutch snap ring (1).
Figure 34 Pry Up Reaction Plate to Seat Against Snap Ring
39. Pry up reverse reaction plate (4) (Figure 34) to seat against snap ring (2).
Figure 35 Measure Reverse Clutch Pack Clearance
40. Set up a dial indicator (1) (Figure 35) on the reverse clutch pack (2).
Figure 36 Press Down on Reverse Clutch and Zero Indicator
41. Using moderate pressure, press down and hold (near indicator) reverse clutch disc (2) (Figure 36) with screwdriver or suitable tool and zero dial indicator (1). When releasing pressure, indicator should advance 0.005-0.010 as clutch pack relaxes.
42. Apply 30 psi (206 kPa) air pressure to the reverse clutch hose on Input Clutch Pressure Fixture 8391. Measure and record reverse clutch pack measurement in four places, 90� apart.
43. Take average of four measurements and compare with reverse clutch pack clearance specification. The reverse clutch pack clearance is 0.89-1.37 mm (0.035-0.054 in.). Select the proper reverse clutch snap ring to achieve specifications:
Reverse Clutch Snap Ring Thickness:
Figure 37 Install No. 2 Needle Bearing
44. To complete the assembly, reverse clutch and overdrive clutch must be removed.
45. Install the #2 needle bearing (note 3 small tabs up) (1) (Figure 37).
Figure 38 Install Underdrive Shaft Assembly
46. Install the underdrive shaft assembly (1) (Figure 38).
Figure 39 Install No. 3 Thrust Washer
47. Install the #3 thrust washer (1) (Figure 39) to the underdrive shaft assembly (2). Be sure five tabs are seated properly.
Figure 40 Install No. 3 Thrust Plate
48. Install the #3 thrust plate (3) (Figure 40) (note 3 tabs) to the bottom of the overdrive shaft assembly (1). Retain with petrolatum or transmission assembly gel (2).
Figure 41 Overdrive/Underdrive Shafts
49. Refer to the exploded view as necessary when performing the following steps (Figure 41).
Figure 42 Install Overdrive Shaft Assembly
50. Install the overdrive shaft assembly (1) (Figure 42).
51. Reinstall overdrive and reverse clutch as shown. Rechecking these clutch clearances is not necessary.
