ASSEMBLY




Figure 27 Measure OD Clutch Pack Clearance






28. Measure OD clutch pack clearance. Set up dial indicator (1) (Figure 27) on top of the OD/Reverse pressure plate (2).
29. Zero dial indicator and apply 30 psi (206 kPa) air pressure to the overdrive clutch hose on Input Clutch Pressure Fixture 8391. Measure and record OD clutch pack measurement in four places, 90� apart.
30. 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 34 Press Down on Reverse Clutch and Zero Indicator






36. Using moderate pressure, press down and hold (near indicator) reverse clutch disc (2) (Figure 34) with screwdriver or suitable tool and zero dial indicator (1). When releasing pressure, indicator should advance 0.005-0.010 as clutch pack relaxes.
37. 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.

Reverse Clutch Snap Ring Thickness:





38. 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:
