Inspection

1.Remove any nicks and burrs from all parts with emery cloth.

CAUTION

Use eye protection such as goggles when using compressed air.

2.Clean all parts with solvent. Dry all parts with com- pressed air.

3.Inspect drive gears and idler gears for the following (Fig. 73):

A.Gear shafts should be free of rough surfaces and excessive wear at bushing points and sealing areas. Scoring, rough surfaces or wear on gear shafts indi- cates need for replacement.

B.Gear teeth should be free of excessive scoring and wear. Any broken or nicked gear teeth must be replaced.

C.Inspect gear face edge for sharpness. Sharp edges of gears will mill into wear plates and, thus, must be replaced.

4.Inspect wear plates for the following:

A.Bearing areas should not have excessive wear or scoring.

B.Face of wear plates that are in contact with gears should be free of wear, roughness or scoring.

C.Thickness of wear plates should be equal.

5.Inspect front flange and rear cover for damage or wear.

Assembly (Fig. 71)

NOTE: When assembling the motor, check the marker line on each part to make sure the parts are properly aligned during assembly.

1.Lubricate O--rings, pressure seals, back--up gaskets and wear plate grooves with a thin coat of petroleum jel- ly. Lubricate all other internal parts freely with clean hy- draulic oil.

2.Install new seals into front flange (Fig. 74):

A.Press shaft seal into front flange until it reaches the bottom of the bore.

B.Install flange washer into front flange and then install retaining ring into the groove of the front flange.

C.Install new dust seal into front flange.
