Power Steering Pumps -: Overhaul: Reassembly
- Place plate and bushing assembly in a suitable holding fixture, with pulley side facing down. Position lower pressure plate in anchor pin with wide chamfered slots at center hole facing up. Lubricate rotor shaft, and insert shaft into lower pressure plate and bushing assembly. If rotor was disassembled, hold cam insert, with notch on O.D. of cam at top, and arrow on O.D. of cam pointing downward.
- Insert rotor in cam with double step in the I.D. of rotor facing upward. With rotor extended upward, approximately 1/2 way out of cam, insert a spring into rotor spring pocket, working in rotor cavity directly beneath cam notch. Use one of the slippers to compress spring, then install slipper, with groove in slipper facing toward cam notch. Flats on side of slipper should be on the left.
- Hold cam stationary and turn rotor either right or left, one space at a time, repeating slipper installation until all slippers have been installed.CAUTION: When turning rotor, use care to prevent springs and slippers already installed from falling out.
Install cam and rotor assembly onto pump housing plate with fixed dowel passing through first hole to left of cam notch when arrow on cam O.D. is pointing toward lower pressure plate. If cam and rotor will not seat, turn rotor shaft slightly until splined teeth mesh, allowing cam and rotor to drop into position.
- Insert loose fitting dowel through cam insert and lower insert into hole in housing plate assembly. Place upper pressure plate, with face having tapered notch down, against cam insert. Fixed dowel should pass through round dowel hole and loose dowel through elongated hole. Install retainer end plate so slot on end plate O.D. matches corresponding notches of upper pressure plate and cam.
- Install pump valve assembly "O" ring seal into pump valve assembly. Place assembly on top of retainer end plate with large exhaust slot on pump valve in line with O.D. notches of previously assembled parts. Stack of parts must be fully seated.
- Install gasket on pump housing plate. Insert pressure plate springs into pockets in pump valve assembly. Use vaseline as an aid to hold springs in position. Using suitable tool (T-69-P-3B586-A Ford), plug intake hole in housing. Lubricate inside of housing and housing cover seal. Fabricate two studs (3/8-16 x 1.55") to be used as positioning guides. Install one in housing plate bolt hole closest to drain hole, and one in bolt hole directly opposite first.
- Align small diameter lube hole in housing rim with lube hole in housing plate. Install housing, applying even downward pressure.CAUTION: Pressure plate springs must not be jarred or moved out of position.
Remove guide studs. Install housing retaining bolts finger tight, then tighten retaining bolts until housing flange contacts gasket. Install 3/8-16 bolt, finger tight, into end of rotor shaft. Using a torque wrench, measure shaft rotational torque. Pump MUST NOT be used if rotational torque exceeds 15 INCH lbs.
- Shake pump assembly back and forth. If it rattles, pressure plate springs have fallen out of their seats and must be reinstalled. Install reservoir "O" ring on housing plate. Install reservoir, aligning notch in reservoir flange with notch in O.D. of pump housing plate and bushing assembly. Install identification tag and outlet valve fitting nut and tighten all nuts and bolts.
