Remove the differential assembly.
(b) Remove the two apply gaskets.
6. REMOVE DRIVE PINION CAP
(a) Remove the bolt.
(b) Using pliers, pull out the drive pinion cap.
(c) Remove the O-rings from the cap.
7. MEASURE DRIVE PINION PRELOAD
Using a torque meter, measure the drive pinion preload.
Preload (at starting): Reused bearing
5 - 8 kg-cm (4.3 - 6.9 in.-lb, 0.5 - 0.8 N-m)
The total preload measured in step 1 minus the drive
pinion preload equals 1.3 - 2.0 kg-cm (1.1 - 1.7 in.-lb,
0.1 - 0.2 N-m). If the result is not within this specifica-
tion, the side bearing preload is bad.

INSPECTION OF OIL PUMP
1. CHECK BODY CLEARANCE OF DRIVEN GEAR
Push the driven gear to one side of the body.
Using a feeler gauge, measure the clearance.
Standard body clearance: 0.07 - 0.15 mm
(0.0028 - 0.0059 in.)
Maximum body clearance: 0.3 mm (0.012 in.)
If the body clearance is greater than the maximum, re-
place the oil pump body subassembly.
2. CHECK TIP CLEARANCE OF DRIVEN GEAR
Measure between the driven gear teeth and the cres-
cent-shaped part of the pump body.
Standard tip clearance: 0.11 - 0.14 mm
(0.0043 - 0.0055 in.)
Maximum tip clearance: 0.3 mm (0.012 in.)
If the tip clearance is greater than the maximum, replace
the oil pump body subassembly.
3. CHECK SIDE CLEARANCE OF BOTH GEARS
Using a steel straightedge and a feeler gauge, measure
the side clearance of both gears.
Standard side clearance: 0.002 - 0.005 mm
(0.0008 - 0.0020 in.)
Maximum side clearance: 0.1 mm (0.004 in.)

There are three different thicknesses for drive and driven
gears.
Drive and driven gear thickness
Mark Thickness
A 9.440 - 9.456 mm (0.3717 - 0.3723 in.)
B 9.456 - 9.474 mm (0.3723 - 0.3730 in.)
C 9.474 - 9.490 mm (0.3730 - 0.3736 in.)
If the thickest gear can not make the side clearance
within standard specification, replace the oil pump body
subassembly.
4. CHECK OIL PUMP BODY BUSHING
Using a dial indicator, measure the inside diameter of
the oil pump body bushing.
Maximum inside diameter: 38.18 mm (1.5031 in.)
If the inside diameter is greater than the maximum, re-
place the oil pump body subassembly.
5. CHECK STATOR SHAFT BUSHING
Using a dial indicator, measure the inside diameter stator
shaft bushing.
Maximum inside diameter: 21.57 mm (0.8492 in.)
If the inside diameter is greater than the maximum, re-
place the stator shaft.
ASSEMBLY OF OIL PUMP
1. INSTALL FRONT OIL SEAL
Using SST and a hammer, install a new oil seal. The
seal end should be flush with the outer edge of the
pump body.
SST 09350-32014 (09351-32140)
2. INSTALL DRIVEN GEAR AND DRIVE GEAR
Make sure the top of the gears are facing upward.
