Vane Pump (For Kd Series Engine) -- Inspection |
| 1. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATES CLEARANCE |
Using a feeler gauge, measure the clearance between the side face of the vane pump rotor groove and the vane pump plates.
- Maximum clearance:
- 0.03 mm (0.0012 in.)
- NOTICE:
- If the clearance is more than the maximum, replace the vane pump plates, vane pump rotor and vane pump cam ring.
- Refer to the following table to select an appropriate combination of vane pump rotor, vane pump cam ring and vane pump plates.
- Combination of vane pump rotor, vane pump cam ring and vane pump plates:
Vane Pump Rotor Part No.
| Vane Pump Cam Ring Part No.
| Vane Pump Plate Part No.

| 2. INSPECT FLOW CONTROL VALVE |
Check the flow control valve for leakage. Close one of the holes and apply compressed air of 392 to 490 kPa (4 to 5 kgf/cm2, 57 to 71 psi) to the hole on the opposite side. Confirm that the air does not flow out of the end holes.
- NOTICE:
- Make sure to use clean and dry air.
If there is leakage, replace the flow control valve.
- NOTICE:
- Check the mark on the front vane pump housing and replace the flow control valve with one having the same mark as that of the front vane pump housing.
- Refer to the following table to select an appropriate combination of front vane pump housing and flow control valve.
- Combination of front vane pump housing and flow control valve:

Coat the flow control valve with power steering fluid.
- NOTICE:
- Make sure to use new power steering fluid.
Insert the flow control valve into the flow control valve installation hole of the front vane pump housing, and check that the flow control valve enters smoothly under its own weight.
If the flow control valve does not enter the front vane pump housing smoothly, replace the flow control valve.
| 3. INSPECT FLOW CONTROL VALVE COMPRESSION SPRING |
Using a vernier caliper, measure the free length of the flow control valve compression spring.
- Minimum free length:
- 29.2 mm (1.150 in.)
If the length is less than the minimum, replace the flow control valve compression spring.
| 4. INSPECT PRESSURE PORT UNION |
If the union seat in the pressure port union sub-assembly is severely damaged, replace the pressure port union sub-assembly.
