Power Steering Pumps: Overhaul: Reassembly
- If rotating group was disassembled, place rotor on shaft with triangle detent (See Fig 1) facing upwards and install retaining ring at end of shaft. Place insert cam over rotor with recessed notch on cam facing upwards.
- With rotor extended approximately half way out of cam, insert springs and slippers (groove facing outward) into rotor cavities beneath recessed cam flats. Index cam either one space right or left at a time about rotor and insert remaining springs and slippers until all 10 cavities are filled. Use care when turning rotor that previously installed springs and slippers do not fall out.
- Using suitable adhesive on outside of seal and primer in seal bore, drive rotor shaft seal into bore with driver tool T78P-3733-A3 (or equivalent). With pulley side of housing facing down, insert two 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 pressure plate over dowels and into housing with seals facing front of pump. Use driver tool (T78P-3733-A3) and "C" clamp to press lower plate into housing until it is felt to bottom.
- Install rotating assembly over dowel pins into housing. (See Fig 1)NOTE: Stepped holes must be used for dowel pins and the recessed notch in cam insert must face toward the reservoir approximately 180° opposite the square mounting lug on housing.
Place upper pressure plate over dowel pins with recess directly over recessed notch on cam insert. (See Fig 2)
- Lubricate and place new "O" ring on valve cover. If plastic baffle is loose in valve cover, apply petroleum jelly to baffle and install 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 and compress valve cover into pump housing. Install retaining ring with ends near access hole in housing.
- Lubricate and install "O" ring on pump housing and install reservoir. Install flow control valve and spring into valve cover. Use new "O" ring seals on outlet fitting and install into valve cover to specified torque.NOTE: 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.
