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.
Vehicle Speed Signal Circuit between Stereo Component Amplifier and Combination
Meter
DESCRIPTION
The stereo component amplifier assembly receives a vehicle speed signal from
the combination meter assembly to control the ASL function.
