Power Steering Pump Overhaul: Reassembly
- If rotating group was disassembled, place rotor on spline shaft. Rotor is symmetrical, and can be installed either way. See Fig 1 . Install retaining ring on end of shaft. Place insert cam over rotor with recessed notch on cam facing up.
- With rotor extended approximately halfway out of cam, insert one spring and slipper (groove facing cam) into one rotor cavity beneath recessed cam flats. Repeat procedure on opposite cavity.
- Index cam one space at a time, either right or left, around rotor. Insert remaining springs and slippers until all 10 cavities are filled. Turn rotor carefully so previously installed springs and slippers do not fall out.
- Using Seal Driver (T78P-3733-A3), install rotor shaft seal into bore until it bottoms. Install seal retainer in same manner. With pulley side of housing facing down, insert 2 dowel pins and Belleville spring (dished surface upward) into housing.
- Lubricate inner and outer "O" rings with power steering fluid and install on lower pressure plate. Insert lower plate over dowels and into housing with seals facing front of pump.
- Install pump into "C" clamp. Using Seal Driver (T78P-3733-A3), press lower plate lightly into pump housing until it bottoms. Install cam, rotor and slippers, and rotor shaft assembly over dowel pins into housing. See Fig 1 .
- Place upper pressure plate over dowel pins with recess directly over recessed notch on cam insert and approximately 180 degrees opposite square mounting lug. See Fig 2 .
- Lubricate and place NEW "O" ring on pump valve cover. If plastic baffle is loose in valve cover, apply petroleum jelly to baffle. Install baffle into position on valve cover.
- Insert valve cover over dowel pins with outlet fitting hole directly in line with square mounting lug on housing. Place assembly in "C" clamp. Compress valve cover into pump housing. Install retaining ring with ends near access hole in housing.
- Lubricate and install NEW "O" ring on pump housing. Install reservoir. Install flow control valve and spring into valve cover.CAUTION: If flow control valve is cocked, it may become stuck in valve cover. DO NOT force valve forward, since chips may shear off and carry into valve bore. Remove flow control valve and reinstall.
- Lubricate and place NEW "O" ring seals in the outlet fitting. Install outlet fitting into valve cover and tighten to specification. See TORQUE SPECIFICATIONS .
