CLEANING AND INSPECTION (Continued)
With the rotor assembly installed in the housing, place a
straight edge over the rotor assembly and the housing.
Measure the clearance (rotor end play) between the
straight edge and the rotor and outer race.
The outer race,
shaft and rotor are replaceable only as an assembly.
Check the drive shaft to housing bearing clearance by
measuring the OD of the shaft and the ID of the housing
bearing. Inspect the relief valve spring for a collapsed or
worn condition. Check the relief valve spring tension. If the
spring is worn or damaged, replace the spring. Check the
relief valve piston for scores and free operation in the bore.
