1 - DIAL INDICATOR 2 - UNDERDRIVE CLUTCH - Using moderate pressure, press down and hold (near indicator) the UD clutch pack (2) with screwdriver or suitable tool and zero dial indicator (1). See Fig 20. When releasing pressure on clutch pack, indicator reading should advance 0.005-0.010 inches.CAUTION: Do not apply more than 30 psi (206 kPa) to the underdrive clutch pack.
- Apply 30 psi (206 kPa) to the underdrive hose on Pressure Fixture 8391 and measure UD clutch clearance. Measure and record UD clutch pack measurement in four (4) places, 90° apart.
- Take average of four measurements and compare with UD clutch pack clearance specification. Underdrive clutch pack clearance must be 0.94-1.50 mm (0.037-0.059 in.).

1 - DIAL INDICATOR 2 - REVERSE CLUTCH - Using moderate pressure, press down and hold (near indicator) reverse clutch disc (2) with screwdriver or suitable tool and zero dial indicator (1). When releasing pressure, indicator should advance 0.005-0.010 inches as clutch pack relaxes.
- Apply 30 psi (206 kPa) air pressure to the reverse clutch hose on Pressure Fixture 8391. Measure and record reverse clutch pack measurement in four (4) places, 90° apart.
- 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.
- To complete the assembly, reverse clutch and overdrive clutch must be removed.
