INSPECTION
PROCEDURE
1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY
(a) Turn the front oil pump drive gear with 2 screwdrivers and check that it rotates smoothly. NOTICE: Be careful not to damage the lip of the front oil pump oil seal. |
|
2. INSPECT CLEARANCE OF FRONT OIL PUMP BODY AND GEAR SUB-ASSEMBLY
(a) Inspect the body clearance:
(1) Pull the front oil pump driven gear to one side of the front oil pump body sub-assembly. |
|
(2) Using a feeler gauge, measure the clearance.
Standard Clearance:
0.12 to 0.17 mm (0.00472 to 0.00669 in.)
Maximum Clearance:
0.17 mm (0.00669 in.)
If the clearance is greater than the maximum, replace the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.
(b) Inspect the side clearance:
(1) Using a straightedge and feeler gauge, measure the side clearance of both gears. Standard Side Clearance: 0.025 to 0.04 mm (0.000984 to 0.00157 in.) Maximum Side Clearance: 0.04 mm (0.00157 in.) Front Oil Pump Drive Gear Thickness:
Front Oil Pump Driven Gear Thickness:
If the clearance is greater than the maximum, replace the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly. |

3. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY
(a) Using a caliper gauge, measure the inside diameter of the front oil pump body sub-assembly bushing. Standard Inside Diameter: 43.135 to 43.160 mm (1.69822 to 1.69921 in.) Maximum Inside Diameter: 43.160 mm (1.69921 in.) If the inside diameter is greater than the maximum, replace the front oil pump body sub-assembly. |
|
4. INSPECT STATOR SHAFT ASSEMBLY
(a) Using a caliper gauge, measure the inside diameter of the stator shaft assembly. Standard Inside Diameter: 22.500 to 22.526 mm (0.88583 to 0.88685 in.) Maximum Inside Diameter: 22.526 mm (0.88685 in.) If the inside diameter is greater than the maximum, replace the stator shaft assembly. |
