INSPECTION
Oil Pump Housing, Oil Pump Cover, Inner Gear and Outer Gear

Check for wear or damage.
Side Clearances

Measure the side clearance of inner and outer gears in at least
four places around each outside edge. Maximum measured val-
ues should be within specified positions.

If the clearance is less than standard, select inner and outer
gear as a set so that clearance is within specifications. Refer to
AT- 5 3 0 , "
SERVICE DATA AND SPECIFICATIONS (SDS)" .

If the clearance is more than standard, replace whole oil pump
assembly except oil pump cover.

Measure the clearance between outer gear and oil pump hous-
ing.

If not within allowable limit, replace whole oil pump assembly
except oil pump cover.
Seal Ring Clearance

Measure the clearance between seal ring and ring groove.

If not within allowable limit, replace oil pump cover assembly.Standard clearance: 0.030 - 0.050 mm (0.0012 - 0.0020 in)
SAT095D
Standard clearance: 0.111 - 0.181 mm (0.0044 - 0.0071 in)
Allowable limit: 0.181 mm (0.0071 in)
SAT096D
Standard clearance: 0.1 - 0.25 mm (0.0039 - 0.0098 in)
Allowable limit: 0.25 mm (0.0098 in)

ASSEMBLY
1. Install oil pump housing oil seal on oil pump housing.
CAUTION:

Do not reuse oil pump housing oil seal.

Apply ATF to outer surface of oil pump housing oil seal.
2. Install O-ring on oil pump housing.
CAUTION:

Do not reuse O-ring.

Apply ATF to O-ring.
3. Install inner and outer gears on oil pump housing.
CAUTION:
Be careful of the direction of inner gear.
4. Install oil pump cover on oil pump housing.
a. Wrap masking tape around splines of oil pump cover assembly
to protect seal. Position oil pump cover assembly on oil pump
housing assembly, then remove masking tape.
b. Tighten bolts in a crisscross pattern. Tighten oil pump cover
bolts to the specified torque. Refer to AT- 4 4 3 , "

3. Remove O-rings from solenoid valves and terminal body.
4. Place control valve upper body facedown, and remove bolts b ,
and nut f .
CAUTION:
Remove bolts with control valve upper body facing down,
because control valve upper body and control valve inter
body may come off and steel ball may fall and be lost.
5. Remove control valve lower body from control valve inter body.
6. Turn over control valve lower body.
7. Remove bolts e , separating plate and support plates from con-
trol valve lower body.
8. Remove check balls and oil cooler relief valve springs from con-
trol valve lower body.
CAUTION:
Be careful not to lose check balls and oil cooler relief valve
springs.
