Power Steering Pump: Service and Repair

CAUTION: Power steering fluid is harmful to paintwork. Should any fluid seep onto the body, chassis, or any other components immediately wipe clean. It is most important that fluid drained from the power steering system is not re-used.

NOTE: The power steering pump is not a serviceable item. In the event of failure or damage a new pump must be fitted.

REMOVE
1. Disconnect the battery negative lead.
2. Loosen the alternator pivot bolts and adjustment link bolts, pivot the alternator inwards and remove the drive belt.
3. Loosen the water pump drive belt idler pulley and remove the drive belt.
4. Remove the left hand bank spark plug leads and detach the distributor cap, place the leads and cap to one side.
5. Disconnect the electrical plug from the distributor amplifier unit.

Power Steering Pump:

6. Loosen the two nuts securing the power steering pump pivot bracket.
7. Release the three bolts securing the pulley to the steering pump, do not remove them at this stage.
8. Release the bottom adjustment bolt below the steering pump and pivot the pump inwards towards the water pump to enable the drive belt to be removed.
9. Remove the three bolts with plain washers retaining the pulley to the pump and withdraw the pulley.

NOTE: Place a drain tray underneath the vehicle to catch any power steering fluid which will seep from the pump when the fluid pipe is disconnected.

Power Steering Pump:

10. Disconnect the fluid pipe from the side of the pump, plug the pipe and pump openings to prevent ingress of dirt.

11. Remove the three bolts securing the pump to the pivot bracket, maneuver the pump out of the bracket and withdraw it from the engine compartment as far as the remaining connected fluid hose will permit.

Power Steering Hose:

12. Release the clamp securing the hose to the pump, remove the hose and plug both openings to prevent ingress of dirt.

REFIT
1. Remove the plug from the fluid hose and secure the hose to a NEW pump. Tighten the hose clamp securely.
2. Maneuver the pump into the pivot bracket and secure in position with the three retaining bolts. Tighten the bolts to 35 Nm (26 ft lb).
3. Remove the plugs from the fluid pipe and steering pump openings and fit the pipe. Tighten the pipe securely.

CAUTION: Care should be taken to ensure that the high pressure fluid pipe is well clear of both the drive belt and the top of the power steering box.

4. Fit the pulley to the steering pump drive flange, coat the three bolts with Loctite(r) and fit to the steering pump, do not fully tighten the bolts at this stage.
5. Refit the crankshaft to steering pump drive belt, pivot the steering pump outwards to tension the belt, tighten the pivot bolts securely. Check that the belt deflects approximately 4-6 mm (0.19-0.25 in) when checked by thumb pressure midway between the crankshaft and pump pulleys.
6. Tighten the three steering pump pulley retaining bolts to 8-12 Nm (6-9 ft lbs).
7. Reverse the remaining removal instructions.
8. Bleed the power steering system.
9. Test the power steering system for leaks with the engine running, holding the steering on full lock in both directions.

CAUTION: Do not maintain this pressure for more than 30 seconds in any one minute, to avoid causing the oil to overheat and possible damage to the seals.

10. Close the hood.
11. Road test the vehicle.
