Tools Required

E-1460-1 Power Steering Pump Shaft Seal Installer

Important: The power steering pump housing bush (2) must be installed so that it is flush with the power steering pump housing (1). The notch (3) in the power steering pump housing bush (2) must be aligned with the power steering pump housing bush lubrication passage (4) in the power steering pump housing (1).

Important: Use a suitable drift to install the bush.

1. If required, install a NEW power steering pump housing bush (2) into the power steering pump housing (1).




Important: Make sure the rear end plate bush (1) is installed to 3.5 mm below the surface of the rear end plate (2).

Important: Use a suitable drift to install the bush.

2. If required, install a NEW rear end plate bush (1) into the rear end plate (2), using a suitable drift.




Important: Lubricating lip type seals with the system lubricant before installation will minimise the potential of seal leakage.

3. Lubricate a NEW power steering pump drive shaft seal (1) with clean power steering fluid.
4. Install the NEW power steering pump drive shaft seal (1) into the power steering pump housing (2) using E-1460-1




Important: Lubricating O-ring seals with the system lubricant before installation will minimise the potential of seal leakage.

5. Lubricate the two NEW thrust plate O-rings (1).

Important: Make sure the O-rings (1) are seated correctly in the housing.

6. Install the O-rings (1) into the housing (2).




Important: The thrust plate must be installed correctly. Due to the asymmetric shape of the plate, it can be installed in either direction.

7. Install the thrust plate (2) to the power steering pump housing (1) with the flat side facing upwards and align the small notch (3) in the plate to the notch (4) in the power steering pump housing (1).




Important: Do not damage the seal lip (3) with the power steering pump drive shaft splines (4) during power steering pump drive shaft installation.

Important: Do not allow the thrust plate to become dislodged from the power steering pump housing.

8. Install the power steering pump drive shaft (1) into the power steering housing (2).




Important: Do not clamp the power steering pump housing (4) with excessive force, as this will distort the power steering pump housing.

9. Support the power steering pump drive shaft (2) by placing a small block of wood under the power steering pump drive shaft and clamp the power steering pump housing (4) in a vice using soft jaws.
10. Install the rotor (1) onto the power steering pump drive shaft (2).

Important: If the full circumference retainer ring does not fit firmly in the groove, replace with a new one. Do not use a conventional Circlip or C-clip. Only use a full circumference retainer ring.

Important: Place the full circumference retainer ring (3) on the shaft and using of soft headed hammer and a deep 11 mm socket, tap the ring into place. Make sure the full circumference retainer ring (3) is correctly seated in the groove.

11. Install the full circumference retainer ring (3) onto the power steering pump drive shaft (2).




Important: If required, use a small amount of petroleum jelly to assist in holding the vanes (1) in place.

12. Install the vane (1), ten places, into the vane channels (2).




Important: Lubricating O-ring seals with the system lubricant before installation will minimise the potential of seal leakage.

13. Lubricate lightly the NEW rear end plate seal (1).

Install the NEW rear end plate seal (1) into the groove in the power steering pump housing (2).

Important: The power steering pump ring must be installed correctly, the "MS" mark must face towards the front of the power steering pump

14. Install the power steering pump ring (3) onto the dowel pins in the rear end plate (4).
15. Install the rear end plate (4) pump ring (3) assembly to the power steering pump housing (2).




Important: The rear end plate (1) must sit within 2 mm (A) of the pump housing (2). If the rear end plate (1) is raised more than 2 mm (A) from the surface of the pump housing (2), remove the rear end plate (1) and realign the thrust plate.

16. Rotate the power steering pump so the rear end plate (1) is vertical.

Carefully remove the rear end plate (1) and make sure all the vanes are in place and manipulate into position if required.

Reinstall the rear end plate (1).

Notice: Refer to Fastener Notice in the Preface section.




17. Install the end plate to power steering pump housing retaining bolts (1).

Tighten
Tighten the bolts in a cross pattern to 30 N·m (22 lb ft).




18. Install the droop flow control valve spring (2) into the power steering pump housing outlet port (3).
19. Lubricate the droop flow control valve (1) with clean power steering fluid.

Important: When installing the droop flow control valve assembly to make sure the valve assembly moves freely within the cavity bore.

20. Install the droop flow control valve (1) into the pump housing outlet port (3).




Important: Lubricating the O-ring seals with the system lubricant before installation will minimise the potential of seal leakage.

21. Lubricate the two NEW O-rings (2)
22. Install the two NEW O-rings (2) to the high pressure outlet fitting (1).
23. Install the high pressure outlet fitting (1) to the power steering pump housing.

Tighten
Tighten the high pressure outlet fitting to 80 N·m.




24. Lubricate the NEW power steering pump inlet pipe O-ring (1).
25. Install NEW power steering pump inlet pipe O-ring (1) onto the power steering pump inlet pipe (2).

Important: The pump inlet pipe (2) must face the same direction as the high pressure outlet when installed correctly.

26. Install the power steering pump inlet pipe (2).
27. Install the power steering pump inlet pipe to power steering pump housing retaining bolt (3).

Tighten
Tighten the bolt to 12 N·m.

28. Install the power steering pump. Refer to Power Steering Pump Replacement .
