Camry V6-3.5L (2GR-FE) (2008)
Power Steering Pump: Testing and Inspection
POWER STEERING: VANE PUMP (for 2GR-FE):
INSPECTION
1. INSPECT VANE PUMP SHAFT AND BUSHING IN VANE PUMP FRONT HOUSING
(a) Using a micrometer, measure the outer diameter [a] of the vane pump shaft with pulley.
(b) Using a vernier caliper, measure the inner diameter [b] of the vane pump front housing bushing.
(c) Calculate the oil clearance.
Oil clearance = Inner diameter of the bushing [b] - Outer diameter of the shaft [a].
Maximum oil clearance:
0.07 mm (0.0028 in.)
If oil clearance exceeds the maximum, replace the vane pump assembly.
2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE CLEARANCE
(a) Using a micrometer, measure the thickness of the vane pump plates.
Standard thickness:
1.405 to 1.411 mm (0.05531 to 0.05555 in.)
If the thickness is not within the specified range, replace the vane pump assembly.
(b) 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.)
If clearance exceeds the maximum, replace the vane pump assembly.
3. INSPECT FLOW CONTROL VALVE ASSEMBLY
(a) Coat the flow control valve assembly with power steering fluid and check that it falls smoothly into the flow control valve due to its own
weight.
If the control valve does not fall into the hole smoothly, replace the vane pump assembly.
