Inspection
Clean all components with mineral spirits and dry them with compressed air. Replace all O-rings.
1. Inspect flow control valve for nicks and scratches. Remove minor imperfections with crocus cloth. Valve should move freely in bore. If valve
sticks inspect valve and housing bore. Replace housing or valve if damaged.
2. Inspect pressure and thrust plates for flatness, and replace if scored, worn, or surfaces are not flat.
3. Inspect pump ring for any wear or damage. A polished appearance is normal. Replace if damaged in any way.
4. Inspect thrust plate dowels, pressure plate spring, rotor and rotor vanes. Replace if worn, cracked or distorted.
5. Inspect pump shaft and splines, and replace shaft retaining ring. Replace shaft if worn, cracked or damaged.
6. Inspect pump housing and bores checking for distortion, cracks and porosity. Inspect pump fitting for any damage. Inspect end plate for wear.
Replace parts if damage is found. If the end plate retaining ring is distorted in any way, it must be replaced.
7. Inspect sleeve assembly and shaft bearing. Replace if worn or damaged.
Assembly
Be sure all parts are clean and well lubricated with power steering fluid only. Dirt in the assembly will cause noise, leaks, and premature wear.
1. Press sleeve assembly with a socket into housing. Make sure sleeve is fully seated. Do not over press sleeve as this could damage O-ring seat.
2. Install O-ring on sleeve assembly. Install short dowel pin in pump housing, then install the pressure plate spring over sleeve assembly into housing.
3. Install O-ring on pressure plate. Place a reference mark on the pressure plate directly over the dowel pin hole in the plate. This mark will help align
short dowel pin and hole when installing pressure plate.
4. Install pressure plate in housing, taking care to fully seat short dowel in pressure plate pin hole, then install two pump ring dowel pins in pressure
plate.
