INSPECTION
PROCEDURE
1. INSPECT VANE PUMP SHAFT AND BUSH IN VANE PUMP FRONT HOUSING
(a) Using a micrometer, measure the outer diameter of the vane pump shaft. Text in Illustration

(b) Using a vernier caliper, measure the inner diameter of the vane pump front housing bush.
(c) Calculate the oil clearance.
Oil clearance = Inner diameter of the bush - Outer diameter of the shaft
Maximum oil clearance:
0.07 mm (0.00276 in.)
If the oil clearance is more than the maximum, replace the vane pump assembly.
2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE
(a) Using a micrometer, measure the thickness of the vane pump plates. Standard thickness: 1.405 to 1.411 mm (0.0554 to 0.0555 in.) Text in Illustration
If the thickness is not as specified, 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 plate. Maximum clearance: 0.025 mm (0.00098 in.) Text in Illustration
If the clearance is more than the maximum, replace the vane pump assembly. |

3. INSPECT PRESSURE PORT UNION
If the union seat in the pressure port union is severely damaged, it may cause fluid leakage. In that case, replace the vane pump assembly.
