15. Measure the distance between the direct clutch backing plate and the bottom of the gage bar. Measure three times in different locations on the backing plate. Record this as H1.
16. Apply air pressure - 65 PSI, to the specified port. Measure the distance between the direct clutch backing plate and the bottom of the gage bar. Measure three times in different locations on the backing plate. Record this as H2.
17. Subtract H2 from H1 this is the clutch pack travel. If the clutch travel is between 1.86 mm (0.073 in) and 1.06 mm (0.042 in) use the current direct clutch backing plate retainer ring (414). If the clutch travel is more than 1.86 mm (0.073 in) use the next size larger direct clutch backing plate retainer ring (414). If the clutch travel is less than 1.06 mm (0.042 in) use the next size smaller direct clutch backing plate retainer ring (414). Refer to Clutch Travel Chart.
