Disassembly Procedure
1. Turn the drive gear with 2 screwdrivers and make
sure it rotates smoothly.
Notice : Be careful not to damage the oil lip.
2. Remove the 8 bolts and stator shaft.
Notice : Be careful not to let the driver drop as it might
come off attached to the stator shaft.
3. Remove the oil pump drive gear and driven gear
from the oil pump body.
Inspection Procedure
1. Push the driven gear to one of side of the body.
Using a feeler gauge, measure the clearance.
S Standard body clearance:
0.10
0.17 mm (0.0039
0.0067 in.)
S Maximum body clearance: 0.17 mm (0.0067 in.)
If the body clearance is greater than the maxi-
mum, replace the oil pump body sub–assembly.

2. Measure the tip clearance between the driven gear
teeth and drive gear teeth.
S Standard tip clearance:
0.07
0.15 mm (0.0028
0.0059 in.)
S Maximum tip clearance: 0.15 mm (0.0059 in.)
If the tip clearance is greater than the maximum,
replace the oil pump body sub–assembly.
3. Using a steel straight edge and feeler gauge, mea-
sure the side clearance of both gears.
S Standard side clearance:
0.02
0.05 mm (0.0008
0.0020 in.)
S Maximum side clearance: 0.05 mm (0.0020 in.)
If the side clearance is greater than the maxi-
mum, replace the drive gear, driven gear or
pump body.
4. Using a dial indicator, measure the inside diameter
of the oil pump body bushing.
S Standard inside diameter: 38.126 mm (1.50102
in.)
S Maximum inside diameter: 38.188 mm (1.50346
in.)
If the inside diameter is greater than the maxi-
mum, replace the oil pump body sub–assembly.
5. Using a dial indicator, measure the inside diameter
of the stator shaft bushings.
S Standard inside diameter: 18.437 mm (0.72586
in.)
S Maximum inside diameter: 18.5 mm (0.728 in.)
If the inside diameter is greater than the maxi-
mum, replace the stator shaft.
