3. REMOVE STATOR SHAFT
(a) Remove the 13 bolts, and then remove the stator shaft
from the oil pump body.
(b) Remove the oil pump body from the torque converter
clutch.
4. 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 drive gear, driven gear or pump body.
5. CHECK TIP CLEARANCE OF DRIVEN GEAR
Measure between the driven gear teeth and the crescet-
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 drive gear, driven gear or pump body.
6. CHECK SIDE CLEARANCE OF BOTH GEARS
Using a steel straight edge and a feeler gauge, measure
the side clearance of both gears.
Standard side clearance:
0.02-0.05 mm (0.0008-0.0020 in.)
Maximum side clearance:
0.1 mm (0.004 in.)
If the side clearance is greater than the maximum, replace
the drive gear, driven gear or pump body.

8. REMOVE OIL SEAL
(a) Pry off the oil seal with a screwdriver.
(b) Using SST, install a new oil seal.
The oil seal end should be flush with the outer edge of the
pump body.
SST 09350-30020 (09351-32140)
(c) Coat the oil seal lip with MP grease.
OIL PUMP BUSHING CHECK
1. CHECK OIL PUMP BODY BUSHING
Using a dial indicator, measure the inside diameter of the
oil pump body bushing.
Maximum inside diameter:
38.19 mm (1.5035 in.)
If the inside diameter is greater than the maximum, re-
place the oil pump body.
2. CHECK STATOR SHAFT BUSHING
Using a dial indicator, measure the inside diameter of the
stator shaft bushing.
Maximum inside diameter (Front):
21.58 mm (0.8496 in.)
Maximum inside diameter (Rear):
27.08 mm (1.0661 in.)
If the inside diameter is greater than maximum, replace
the stator shaft.
OIL PUMP ASSEMBLY
1. INSTALL DRIVEN GEAR AND DRIVE GEAR TO OIL
PUMP BODY
(a) Place the oil pump body on the torque converter clutch.
(b) Coat the driven gear and drive gear with ATF.
(c) Install the driven gear and drive gear.

2. INSTALL STATOR SHAFT TO OIL PUMP BODY
(a) Align the stator shaft with each bolt hole.
(b) Tighten the 13 bolts.
Torque: 10 N´m (100 kgf´cm, 7 ft´lbf)
3. INSTALL OIL SEAL RINGS
(a) Coat the 2 oil seal rings with ATF.
(b) Install the 2 oil seal rings to the stator shaft groove, then
snug them down by squeezing their ends together.
NOTICE: Do not spread the ring ends too much.
HINT: After installing the oil seal rings, check that they ro-
tate smoothly.
4. CHECK OIL PUMP DRIVE GEAR ROTATION
Make sure the drive gear rotates smoothly.

SECOND COAST BRAKE BAND
INSPECTION
INSPECT BRAKE BAND
If the lining of the brake band is peeling off or discolored,
or even if parts of the printed numbers are defaced, re-
place the brake band.
HINT: Before assembling the new band, soak it in ATF for
at least 15 minutes.
SECOND COAST BRAKE PISTON
ASSEMBLY
1. SELECT PISTON ROD
If the band is OK with piston rod stroke not within the stan-
dard value, select a new piston rod.
HINT: There are 5 different piston rod lengths.
Piston rod length:
70.7 mm (2.783 in.)
71.4 mm (2.811 in.)
72.2 mm (2.843 in.)
72.9 mm (2.870 in.)
73.7 mm (2.902 in.)
2. ASSEMBLE SECOND COAST BRAKE PISTON
