TOYOTA CAMRY V20 1986 Service Information

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 component group. If a component group can not be assembled because parts are being or-
dered, be sure tc keep all parts of that group in a separate container while proceeding with dis-
assembly, inspection, repair and assembly of other component groups.
Recommended fluid for the automatic transaxle is ATF type DEXRON) ll.
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean with any fluid passages and holes blown trough wit com-
pressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent accidentally spraying,
automatic transmission fluid or kerosene in your face.
3. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in proper order to allow efficient inspection, repairs, an(
reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corresponding spring
3. New brakes and clutches that are to be used for replacement must be soaked in transaxle fluid for a least
fifteen 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 be replaced.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.

ASSEMBLY OF SECOND COAST BRAKE
PISTON
1. SELECT PISTON ROD
If the band is OK with piston stroke not within the standard value,
select the piston rod.
Piston stroke: 1.5 ± 3.0 mm (0.059 ± 0.118 in.)
There are two lengths of piston rod.
Piston rod length: 72.9 mm (2.870 in.)
71.4 mm (2.811 in.)
2. INSTALL PISTON ROD
(a) Install the washer and spring to the piston rod.
INSPECTION OF SECOND COAST BRAKE
COMPONENT
INSPECT BRAKE BAND
If the lining of the brake band is exfoliated or discolored,
or even part of the printed numbers are defaced, replace the
brake band.(b) Remove the spring, washer and piston rod.
(b) Install an E±ring while pushing the piston.

3. INSTALL OIL SEAL RING
(a) Apply ATF to the oil seal ring.
(b) Install the oil seal ring to the piston.
NOTICE: Do not spread the ring ends more than
necessary.

DISASSEMBLY OF OIL PUMP
1. REMOVE OIL SEAL RINGS
Remove the two oil seal rings from the stator shaft
back, side.
2. REMOVE THRUST WASHER FROM STATOR SHAFT
BACK SIDE
Oil Pump
± AUTOMATIC TRANSAXLEComponent Parts (Oil Pump) (A140L and A140E)AT±82

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, r
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, re-
place the oil pump body subassembly.
3. CHECK SIDE CLEARANCE OF BOTH GEARS
Using a steel straightedge and a feeler gauge, mea-
sure 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.) 3. REMOVE STATOR SHAFT
Remove the eleven bolts and stator shaft.
Keep the gears in assembly order.
4. REMOVE FRONT OIL SEAL
Pry off the oil seal with a screwdriver.

There are three different thicknesses for drive and driven
gears.
Drive and driven gear thickness
Mark Thickness
A 9.440 ± 9.455 mm (0.3717 ± 0.3723 in.)
g 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 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 BUSHINGS
Using a dial indicator, measure the inside diameter of
the stator shaft bushings.
Maximum inside diameter:
Front side 21.57 mm (0.8492 in.)
Rear side 27.07 mm (1.0657 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.

6. INSTALL TWO OIL SEAL RINGS ON OIL PUMP
Spread the rings apart and install them into the groove.
NOTICE: Do not spread the ring ends too much.
HINT: After installing the oil seal rings, check that they
move smoothly. 3. INSTALL STATOR SHAFT ONTO PUMP BODY
Align the stator shaft with each bolt hole.
4. TIGHTEN ELEVEN BOLTS
Torque: 100 kg±cm (7 ft±lb, 10 N±m)
5. INSTALL THRUST WASHER
(a) Coat the thrust washer with petroleum jelly.
(b) Align the tab of the washer with the hollow of the pump
body.
7. CHECK PUMP DRIVE GEAR ROTATION
Turn the drive gear with screwdrivers and make sure that
it rotates smoothly.
NOTICE: Be careful not to damage the oil seal lip.
