Power Steering Pump: Testing and Inspection
Cleaning
CLEANING
Wash all parts except seals in a chlorinated solvent and dry with compressed air.
INSPECTION
To determine when to replace power steering pump components, follow these guidelines. Some components must be replaced regardless of condition.
1. Reuse the fittings if the corners are not rounded and the threads are intact.
2. Replace all O-rings.
3. Reuse the rotor and cam assembly if wear is limited to removal of the phosphate coating on the cam contour. Check the cam inside diameter
surface for scoring or burrs. Check the rotor faces and outside diameter for scoring and chipping. Do not repair or refinish the cam or rotor
assembly. If wear or burrs are evident, replace the parts.
4. Install a new rotor and cam assembly if the vanes are worn.
5. Reuse the power steering pump housing if all the threaded holes are not damaged beyond repair. Repair the threaded holes by drilling out the
damaged threads and installing helicoil inserts.
6. Reuse the power steering pump valve if the valve bore is free of burrs, nicks and scoring. The power steering pump valve must fall freely in the
valve bore. Replace the power steering pump housing and/or the power steering pump valve if the power steering pump valve sticks in the bore.
