1. INSTALL VANE PUMP HOUSING OIL SEAL

1. Coat a new vane pump housing oil seal lip with power steering fluid.

1. Using SST and a press, install a new oil seal.

   SST
     09950-60010 (09951-00280)
     09950-70010 (09951-07100)

   NOTICE:
     Make sure that the oil seal is installed facing in the correct direction.

2. INSTALL SHAFT SUB-ASSEMBLY WITH PULLEY

1. Coat the busing inner surface of the front vane pump housing with power steering fluid.

1. Gradually insert the vane pump shaft.

   NOTICE:
     Do not damage the vane pump housing oil seal lip in the front vane pump housing.

3. INSTALL FRONT VANE PUMP SIDE PLATE

1. Coat a new O-ring with power steering fluid and install it onto the front vane pump housing.

1. Coat a new O-ring with power steering fluid and install it onto the side plate.

1. Align the dent of the side plate with that of the front vane pump housing and install the side plate.

   NOTICE:
     Make sure that the side plate is installed facing in the correct direction.

4. INSTALL VANE PUMP CAM RING

1. Align the dent of the cam ring with that of the side plate and install the cam ring with the inscribed mark facing outward.

5. INSTALL VANE PUMP ROTOR

1. Install the vane pump rotor with the inscribed mark facing outward.

1. Coat the 10 vane plates with power steering fluid.

1. Install the vane pump rotor with the round ends facing outward.

1. Using a snap ring expander, install a new snap ring onto the pulley shaft.

6. INSTALL REAR VANE PUMP HOUSING

1. Coat a new O-ring with power steering fluid and install it onto the vane pump housing rear.

1. Align the straight pin of the vane pump housing rear with the dents of the cam ring, side plate and front vane pump housing, and install the rear vane pump housing with the 4 bolts.

   Torque:
     22 N*m{ 224 kgf*cm , 16 ft.*lbf }

7. INSPECT PRELOAD

1. Check that the pump rotates smoothly without making any abnormal noises.
