dial indicator on top of the OD/Reverse reaction plate
as shown in (Fig. 246).
(26) Zero dial indicator and apply 30 psi (206 kPa)
air pressure to the overdrive clutch hose on Tool

ment in four (4) places, 90° apart.
(27) Take average of four measurements and com-
pare with OD clutch pack clearance specification.
The overdrive (OD) clutch pack clearance is
1.07-3.25 mm (0.042-0.128 in.).
