Toyota Tacoma (2015-2018) Service Manual: Inspection
INSPECTION
PROCEDURE
1. INSPECT OIL CLEARANCE
(a) Using a micrometer and caliper gauge, measure the oil seal clearance.
Standard clearance:
0.021 to 0.043 mm (0.0008 to 0.0017 in.)
Maximum clearance:
0.07 mm (0.0028 in.)
If it is greater than the maximum, replace the vane pump assembly.
2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE
(a) Using a micrometer, measure the height, thickness and length of the vane plates.
Minimum height:
7.7 mm (0.303 in.)
Minimum thickness:
1.408 mm (0.0554 in.)
Minimum length:
11.993 mm (0.4722 in.)
|
(b) Using a feeler gauge, measure the clearance between a side face of the vane pump rotor groove and vane plate. Maximum clearance: 0.025 mm (0.0012 in.) If it is greater than the maximum, replace the vane pump assembly. |
|
3. INSPECT FLOW CONTROL VALVE

(a) Coat the flow control valve with power steering fluid and check that it falls smoothly into the flow control valve hole under its own weight.
|
(b) 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 hole. If necessary, replace the vane pump assembly. |
|
4. INSPECT COMPRESSION SPRING
(a) Using vernier caliper, measure the free length of the spring.
Minimum free length:
36.9 mm (1.453 in.)
If it is not within the specification, replace the vane pump assembly.
5. INSPECT PRESSURE PORT UNION SUB-ASSEMBLY
(a) If the union seat in the pressure port union is badly damaged, it could cause fluid leakage, so replace the vane pump assembly.
