   Measure the clutch pack height.

   Description		Reading
   A.	Place the low/reverse clutch pack on the Clutch End Play Gauge with the wave spring down and the pressure plate on top. Using the Dial Indicator Gauge with Holding Fixture, 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. 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.
