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 fluid for the automatic transaxle: ATF D±@@@@@: [g 2] or DEXRON®@@@@@: [g
3](DEXRON®@@@@@: [g 2])
1. GENERAL CLEANING NOTES:
(a) All disassembled parts should be washed clean and any fluid passages and holes blown through with
compressed air.
(b) When using compressed air to dry parts, always aim away from yourself to prevent accidentally spray-
ing automatic transaxle fluid or kerosene in your face.
(c) The recommended automatic transaxle fluid or kerosene should be used for cleaning.
2. PARTS ARRANGEMENT:
(a) After cleaning, the parts should be arranged in the correct order to allow efficient inspection, repairs,
and reassembly.
(b) When disassembling a valve body, be sure to keep each valve together with the corresponding spring.
(c) New brakes and clutches that are to be used for replacement must be soaked in transaxle fluid for at
least fifteen minutes before assembly.
3. GENERAL ASSEMBLY:
(a) All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with
transmission fluid prior to reassembly.
(b) All gaskets and rubber O±rings should be replaced.
(c) Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the
groove correctly.
(d) If a worn bushing is to be replaced, the subassembly containing that bushing must be replaced.
(e) Check thrust bearings and races for wear or damage. Replace if necessary.
(f) Use petroleum jelly to keep parts in place.

3. REMOVE STATOR SHAFT
Remove the 11 bolts and stator shaft.
HINT: Keep the gears in assembly order.
4. REMOVE FRONT OIL SEAL

OIL PUMP BUSHING INSPECTION
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:
0.30 mm (0.0118 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:
0.30 mm (0.0118 in.)
If the tip clearance is greater than the maximum, replace
the oil pump body subassembly.

AUTOMATIC TRANSAXLEOIL PUMP ±
AX±39
3. CHECK SIDE CLEARANCE OF BOTH GEARS
Using a steel straightedge and 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:
0.100 mm (0.0039 in.)
There are 3 different thicknesses for drive and driven
gears.
Drive and driven gear thickness
MarkThickness mm (in.)
A9.440±9.456 (0.3717±0.3723)
B9.456±9.474 (0.3723±0.3730)
C9.474±9.490 (0.3730±0.3736)
If the thickest gear can not make the side clearance within
standard specification, replace the oil pump body subas-
sembly.
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.
OIL PUMP ASSEMBLY
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.

NOTICE: Do not spread the ring ends more than necessary.
HINT: After installing the oil seal rings, check that they
move smoothly.
6. CHECK PUMP DRIVE GEAR ROTATION
