Inspection

1. Clean all parts except the driveshaft oil seal in cleaning fluid. The seal will be damaged if immersed in cleaning fluid.
2. Check fit of vanes in slots of rotor for tightness or excessive looseness. Vanes must fit snugly but slide freely in slots in rotor. Tight fit of vanes in rotor can usually be corrected by thorough cleaning. Replace rotor if excessive looseness exists between rotor and vanes. Replace vanes if worn or scored.
3. Examine machined surface of pump ring for roughness or wear. Replace ring if roughness cannot be corrected with crocus cloth.
4. Inspect thrust plate, pressure plate and end plate for wear, scores or other damage.
5. Inspect pump housing for cracks or damage. Check housing for evidence of wear or scoring.
6. Check all springs for free length, distortion or collapsed coils.
7. Inspect locating dowel pins for distortion.
8. Examine outer diameter of flow control valve for scoring or roughness. Slight damage may be cleaned up with crocus cloth. Check valve assembly for freedom of movement in bore of pump housing.
9. Check all oil passages in pump parts for obstruction. Use a piece of tag wire to clean out holes.
10. Check bushing in pump housing for wear or damage.
