• Measure side clearance of inner gear and outer gear in at leastfour places around each outside edge. Clearances measured val-
ues should be within the specified clearance.
• If clearance is less than standard, select inner gear and outer gear as a set so that clearance is within specifications. Refer to “Parts
Information” for the inner gear and outer gear selection.
• If clearance is more than standard, replace whole oil pump assem- bly except oil pump cover.
• Measure clearance between outer gear and oil pump housing.
• If not within allowable limit, replace whole oil pump assembly except oil pump cover.
Seal Ring Clearance
• Measure clearance between seal ring and ring groove.
• If not within allowable limit, replace oil pump cover 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 inner gear and outer gear on oil pump housing. CAUTION:
Be careful with the di rection of inner gear.
3. 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 oil pump cover bolts in the order as shown, and then tighten them to the specified torque in the same order. Refer to
AT-278, "
Oil Pump".
4. Install seal rings (1) to oil pump assembly (2) carefully after packing ring groove with petroleum jelly.
CAUTION:
Do not spread gap of seal ri ngs (1) excessively while install-
ing. The seal rings (1) may be deformed.

Bolt length, number and location:
*: Reamer bolt and nut.
1. Remove bolts (A), (D), reamer bolt (F) and nut, and remove oil strainer (1) from control valve assembly.
2. Remove bolts (A), (C) and (G), and then remove solenoid valve assembly (1) from control valve assembly.
3. Remove O-rings from solenoid valves and terminal body.
4. Place control valve upper body face down, and remove bolts (B), reamer bolt (F) and nut.
CAUTION:
Remove bolts with control val ve 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.
