1996 Buick Roadmaster BaseSECTION Reassembly
- Lubricate all "O" rings and sealing areas with power steering fluid. Place pump housing on flat surface. Using Shaft Oil Seal Installer (J-22670), drive new shaft seal into bore. To prevent seal from being distorted, DO NOT use excessive force.
- Clamp pump housing in vise with shaft down. Install end cover and pressure plate "O" rings in grooves in pump cavity. With drive shaft clamped (splined end up), install thrust plate on drive shaft with ported side up. See Fig 1 .
- Slide rotor over splines, and install rotor lock ring. Insert both dowel pins in holes of pump cavity. Rotor must move freely on splines. Install drive shaft assembly into pump body, ensuring dowel pins are properly engaged in thrust plate.
- Install vanes in rotor slots. Slide pump ring over rotor on dowel pins with arrows facing up. See Fig 2 . Position pressure plate on dowel pins with plate spring groove facing upward. Place a 1 1/4" socket in groove of pressure plate. Seat entire assembly on "O" ring in pump cavity by pressing down with both thumbs.
- Place pressure plate spring into groove in pressure plate. Position end cover lip edge up over spring. Press end cover down below retainer ring groove with thumb. Install retainer ring. Ensure ring is seated in groove. Use care to avoid cocking end cover in bore or distorting assembly.
- Install flow control valve in bore, with control valve spring and hex end of valve facing interior of bore. Using new "O" rings, install union bolt (or VES actuator) into flow control valve bore and tighten to specification. See TORQUE SPECIFICATIONSΒ . Install pump pulley.
