Fig. 3 Valve Cover Retaining Ring Removal:

Disassemble

1. Remove pulley from pump, Fig. 1.
2. Remove outlet fitting, flow control valve and flow control valve spring from pump, then remove reservoir.
3. Place a suitable C-clamp in a vise.
4. Position lower support plate T78P-3733-A2, or equivalent, over pump rotor shaft.
5. Install upper compressor plate T78P-3733-A1, or equivalent, into upper portion of C-clamp.
6. While holding compressor tool, place pump assembly into C-clamp with rotor shaft facing downward, Fig. 2.
7. Tighten C-clamp until a slight bottoming of valve cover is observed.
8. Through small hole located on side of pump housing, insert a suitable drift and push inward on valve cover snap ring. While pushing inward on snap ring, place a screwdriver under snap ring edge and remove ring from housing, Fig. 3.
9. Loosen C-clamp and remove upper compressor plate T78P-3733-A2, or equivalent, then remove pump assembly.
10. Remove pump valve cover and O-ring.
11. Remove rotor shaft, upper plate, cam and rotor assembly and two dowel pins.
12. Remove lower plate and spring, by tapping housing on a flat surface.
13. Using a suitable screwdriver, remove rotor shaft seal.

Fig. 5 Slippers Installation:

Assemble

1. Position rotor on rotor shaft splines with triangle detent on rotor counterbore facing upward, Fig. 1.
2. Install snap ring into groove on end of rotor shaft.
3. Position insert cam over rotor. Ensure recessed notch on insert cam is facing upward.
4. With rotor extended upward approximately half out of cam, insert spring into rotor pocket, Fig. 4.
5. Use a slipper to compress spring, then install slipper with groove facing cam, Fig. 5.
6. Perform steps 4 and 5 on slipper cavity beneath opposite inlet recess.
7. While holding cam stationary, index rotor left or right one space and install another spring and slipper until all ten rotor cavities have been filled. Use care when turning rotor that springs and slippers remain in position.
8. Apply Loctite No. 242 or 271 adhesive or equivalent to outside diameter of seal and Loctite NF or T primer or equivalent to seal bore in housing. Install rotor shaft seal using tool No. T78P-3733-A3, or equivalent. Using a plastic mallet, drive seal into bore until properly seated.
9. Position pump plate on flat surface with pulley side facing downward.
10. Install two dowel pins and spring into housing. Spring must be inserted with dished surface facing upward.
11. Lubricate inner and outer O-ring seals with power steering fluid, then install seals on lower pressure plate.
12. Install lower pressure plate into housing and over dowel pin with O-ring seals facing toward front of pump. Position assembly on C-clamp. Place tool No. T78P-3733-A3, or equivalent, into rotor shaft hole and press on lower plate lightly until it bottoms in pump housing. This will seat the outer O-ring seal.

Fig. 8 Valve Cover Installation:

13. Install cam, rotor, rotor and slippers and rotor shaft assembly into pump housing over dowel pins. When installing assembly into pump housing, stepped holes must be used for dowel pins and notch in cam insert must be toward reservoir and approximately 180 degrees opposite square mounting lug on housing, Fig. 6.
14. Position upper pressure plate over dowel pins with recess directly over recessed notch on cam insert and approximately 180 degrees opposite square mounting lug, Fig. 7.
15. Lubricate O-ring seal with power steering fluid, then position O-ring on valve cover. Ensure plastic baffle is securely in position on valve cover. A coat of petroleum jelly may be used to hold baffle in position.
16. Insert valve cover over dowel pins. Ensure outlet fitting hole in valve cover is aligned with square mounting lug on housing, Fig. 8.
17. Place assembly in C-clamp and compress valve cover into pump housing until snap ring groove on housing is exposed.
18. Install valve cover snap ring in pump housing. Ensure snap ring ends are near access hole in pump housing.
19. Remove pump assembly from C-clamp.
20. Lubricate O-ring seal with power steering fluid, then place seal on pump housing.
21. Install reservoir on pump housing.
22. Install flow control valve and spring into valve cover.
23. Lubricate O-ring seals with power steering fluid, then place seals on outlet fitting.
24. Install outlet fitting on valve cover. Tighten outlet fitting to specifications. Use care not to cock flow control valve when installing. Do not force valve forward otherwise damage to housing may result.
