COMPONENT PARTS
GENERAL NOTES
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar-looking parts of different subassemblies being on your work-
bench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the next compo-
nent group. If a component group cannot be assembled because parts are being ordered, be sure to keep
all parts of that group in a separate container while proceeding with disassembly, inspection, repair and
assembly of other component groups.
Recommended ATF:
Type T-II or equivalent
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean and any fluid passages and holes blown through with
compressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent accidentally spray-
ing automatic transmission fluid or kerosene on your face.
3. The recommended automatic transmission fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in the correct order to allow efficient inspection, repairs,
and reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corresponding spring.
3. New discs for the brakes and clutches that are to be used for replacement must be soaked in transmis-
sion fluid for at least 15 minutes before assembly.
GENERAL ASSEMBLY:
1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with
transmission fluid prior to reassembly.
2. All gaskets and rubber O-rings should be replaced.
3. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the
groove correctly.
4. If a worn bushing is to be replaced, the subassembly containing that bushing must also be replaced.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.

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.
7. REMOVE OIL PUMP DRIVE GEAR AND DRIVEN GEAR

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.

3. CHECK PISTON STROKE OF OVERDRIVE DIRECT
CLUTCH
(a) Place the oil pump onto the torque converter clutch, and
then place the O/D direct clutch assembly onto the oil
pump.
(b) Using SST and a dial indicator, measure the O/D direct
clutch piston stroke while applying and releasing com-
pressed air (392-785 kPa, 4-8 kgf/cm
2 or 57-114 psi).
SST 09350-30020 (09350-06120)
Piston stroke:
1.45-1.70 mm (0.057-0.067 in.)
If the values are non-standard, inspect the discs.
4. REMOVE FLANGE, PLATES AND DISCS
(a) Using a screwdriver, remove the snap ring from the O/D
direct clutch drum.
(b) Remove the flange, 2 plates and 2 discs.
5. REMOVE PISTON RETURN SPRING

(c) Using a screwdriver, install the snap ring.
6. CHECK PISTON STROKE OF OVERDRIVE DIRECT
CLUTCH
(a) Place the oil pump onto the torque converter clutch, then
place the O/D direct clutch assembly onto the oil pump.
(b) Using SST and a dial indicator, measure the overdrive di-
rect clutch piston stroke while applying and releasing
compressed air (392-785 kPa, 4-8 kgf/cm
2 or 57-114
psi).
SST 09350-30020 (09350-06120)
Piston stroke:
1.45-1.70 mm (0.057-0.067 in.)
