Power Steering Pump: Reassembly
- Lubricate NEW shaft seal with power steering fluid. Drive seal into housing using suitable socket. Install thrust plate, rotor and retaining ring onto shaft to form shaft assembly. See Figure . Install shaft assembly into housing.
- Install dowel pins through thrust plate into housing. Install pump ring into housing, ensuring indentation on pump ring is facing upward. See Fig 1 . Install vanes into pump rotor (vanes can be installed in either direction).
- Install NEW lubricated pump housing "O" ring into housing groove. Align holes in pressure plate with dowel pins, and then install pressure plate. Position pressure plate spring against pressure plate (spring can be installed in either direction).
- Install NEW lubricated "O" ring onto end cover. Lubricate outer edge of end cover. Press end cover into housing far enough to install retaining ring. Ensure retaining ring is fully seated in groove.
- If vehicle is not VES actuator equipped, go to next step. If vehicle is VES actuator equipped, install large, medium and small "O" rings in correct locations. Install discharge fitting onto VES actuator. Install flow control valve spring and valve into pump housing. Orientation of valve must be as shown in illustration. See Figure . Position VES actuator and discharge fitting onto pump assembly. Tighten actuator to specification with VES (EVO) Socket (SA9116C), or equivalent. See TORQUE SPECIFICATIONS . Position electrical connector in-line with pump shaft, and pointing to rear. Install locating clip. Install pump pulley using Pulley Replacer (SA9162C), or equivalent.
- Install NEW lubricated reservoir "O" ring onto reservoir. Push reservoir straight into pump housing. Install reservoir retaining clips. Install pump. See POWER STEERING PUMP under REMOVAL & INSTALLATION. Fill and bleed hydraulic system. See HYDRAULIC SYSTEM BLEEDING under LUBRICATION.
NOTE:
Pump will not operate if pump ring is installed with indentation on pump ring facing downward. See Fig 1
