    READING DESCRIPTION CHART
    
    

    	Description	Reading
    A. Place the low/reverse clutch pack on the Clutch End Play Gauge 307-555 with the wave spring down and the pressure plate on top. Using the Dial Indicator Gauge with Holding Fixture 100-002, place the plunger on the pressure plate. Slide the clutch to the side so the plunger of the Dial Indicator is touching the gauge plate of the Clutch End Play Gauge 307-555. Zero out the Dial Indicator Gauge.
    B. Carefully lift the plunger enough to slide the clutch pack under the plunger to take a reading. Record this reading. Rotate the clutch pack 180 degrees and take a second reading. Add the first and second readings together and divide the total by 2. Record this reading as B.

11. Using the Depth Micrometer 303-D075, measure the piston to center support shoulder height.
    READING DESCRIPTION CHART
    
    

    Description	Reading
    Measure the piston to center support shoulder height. Record this measurement. Rotate the center support 180 degrees and record this measurement. Add the first and the second measurements, then divide by 2. Record this as reading C.

12. Calculate the end clearance.
    READING DESCRIPTION CHART
    
    

    Description	Reading
    Subtract B and C from A to determine end clearance
    Total C measurement
    End clearance specification	1.0-1.6 mm (0.039-0.062 in)

    Compare the end clearance to the specification. If the end clearance is out of specification, select the next thinner or thicker plate as required and repeat Steps  10,  11 and  12.
