PROCEDURE
INSTALL VANE PUMP HOUSING OIL SEAL
Coat the lip of a new vane pump housing oil seal with power steering fluid.
Using SST and a press, press in the vane pump housing oil seal to the front vane pump housing.
Note
Make sure that the vane pump housing oil seal is installed in the correct direction as shown in the illustration.
INSTALL VANE PUMP SHAFT
| *a | Power Steering Fluid |
Coat the inside surface of the bushing in the front vane pump housing with power steering fluid.
Gradually insert the vane pump shaft from the pulley side.
INSTALL VANE PUMP ROTOR
Install the vane pump rotor.
Tech Tips
The vane pump rotor has no specific direction.
Using a snap ring expander, install a new vane pump shaft snap ring to the vane pump shaft.
Coat all 10 vane pump plate with power steering fluid.
| *a | Round End |
| *b | Inward |
| *c | Outward |
Install the vane pump plates with the round end facing outward.
Note
Make sure that the vane pump plate are installed in the correct direction.
INSTALL VANE PUMP CAM RING
| *a | Inscribed Mark |
Align the holes of the vane pump cam ring withe the 2 straight pins, and install the vane pump cam ring with the inscribed mark facing upward.
Note
Make sure that the cam ring is installed in the correct direction.
INSTALL FRONT VANE PUMP SIDE PLATE
Coat a new O-ring with power steering fluid and install it onto the rear vane pump side plate.
Align the groove of the cam ring with that of the rear vane pump side plate, and install the rear vane pump side plate.
Install the wave washer so that its protrusions fit into the slots in the rear vane pump side plate.
INSTALL REAR VANE PUMP HOUSING
Install a new gasket.
Coat a new O-ring with power steering fluid and install it to the rear vane pump housing.
Install the rear vane pump housing with the 4 bolts.
INSPECT ROTATING TORQUE
Check that pump rotates smoothly without abnormal noise.
Temporarily install the vane pump pulley set nut to the vane pump shaft.
Using a torque wrench, measure the rotating torque.
| Standard rotating torque |
|---|
| 0.27 N*m (3 kgf*cm, 2 in.*lbf) or less |
If the rotating torque is not as specified, check the installation of the vane pump housing oil seal.
INSTALL FLOW CONTROL VALVE
Coat the compression spring and flow control valve with power steering fluid.
Install the compression spring and flow control valve.
Coat a new O-ring with power steering fluid and install it onto the pressure port union.
Install the pressure port union to the front vane pump housing.
INSTALL POWER STEERING SUCTION PORT UNION
Coat a new O-ring with power steering fluid and install on to the suction port union.
Install the suction port union to the front vane pump housing with the bolt.
