lift the support off the oil pump.

Inspect the interlocking seal rings (Fig. 84) on the

reaction shaft support for wear or broken locks,

remove the rings unless conditions warrant. Inspect

the machined surfaces on the oil pump body and re-

action shaft support for nicks and burrs. Inspect the

pump body and reaction shaft support bushings for

wear or scores. Inspect the oil pump rotors for scor-

in the pump body, place a straight edge across the

face of the rotors and the pump body. Use a feeler

gauge to measure the clearance between straight

edge and face of the rotors. Clearance limits are from

.001 to .0025 inch. Also, measure the rotor tip clear-
