Outer Rotor to Inner Rotor Tip Clearance
Determine the outer rotor to inner rotor tip clearance. Insert a
feeler gauge between the top of an inner rotor tooth (1, Figure
330) and the top of an outer rotor tooth (2, Figure 330) and
measure the clearance.
Record the measurement(s) and see Outer Rotor to Inner Rotor
Tip Clearance on page 9-11 for the service limits.
Check Outer Rotor Side Clearance
Determine the side clearance of the outer rotor across the
pump cavity. Measure the depression using a depth
micrometer (1, Figure 331).
Record the measurement(s) and see Check Outer Rotor Side
Clearance on page 9-12 for the service limits.
Check Rotor Shaft Clearance
Determine the rotor shaft clearance. Measure the outside
diameter of the rotor shaft (1, Figure 332) and the bore diameter
in the gear case housing (2, Figure 332).
Calculate the difference between the two measurements to
determine the clearance.
