8.Inspect the wearplate (18) for cracks, peening, and scoring. A polished pattern on the wear plate from rotor rotation is normal. Replace as necessary.
9.Inspect drive link (13) for cracks and worn or dam- aged splines. No perceptible lash (play) should be noted between mating spline parts of the rotor (19) or coupling shaft (11). Replace as necessary (Fig. 39).
10.Inspect thrust bearing (12) for wear, peening, corro- sion and a full complement of retained rollers. Replace as necessary.
11.Inspect coupling shaft (11) internal and external splines and keyway for damage and wear. Inspect bear- ing and sealing surfaces of the coupling shaft for chip- ping, nicks, grooves, severe wear, corrosion, and discoloration. Replace coupling shaft if any of these conditions exist. Minor shaft wear in seal area is permis- sible. If wear exceeds 0.020 inch (0.51 mm) diametrical- ly, replace coupling shaft. A slight ºpolishº is permissible on the shaft bearing areas (Fig. 40).
Note: Do not remove inner bearing (10), thrust wash- ers (8), thrust bearing (9), inner seal (7), backup wash- ers (6 and 4), and outer bearing (2) from the housing (3). These parts should be inspected in place.
12.Inspect housing (3) for cracks. Inspect machined surfaces for nicks, burrs, peening, and corrosion. Re- move burrs that can be removed without changing di- mensional characteristics. Inspect tapped holes for thread damage. If the housing is defective in these areas, discard the housing assembly (Fig. 41).
13.If the housing (3) has passed inspection to this point, inspect outer bearing (2), inner bearing (10), thrust washers (8), and thrust bearing (9). Bearing roll- ers must be firmly retained in the bearing cages but must rotate and orbit freely. All rollers and thrust washers must be free of peening and corrosion. If any bearing or thrust washer does not pass inspection, replace the housing (3) as a complete assembly (Fig. 42).
