INSPECTION
Oil Pump Housing, Oil Pump Cover, Inner Gear and Outer Gear
Check for wear or damage. Replace if necessary.
Side Clearances

Measure side clearance of inner gear and outer gear in at least
four places around each outside edge. Clearances measured
values 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
assembly 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.Standard clearance: Refer to AT- 3 8 2 , "

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 direction 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 fitting bolts in the order as shown in the
figure, and then tighten them to the specified torque in the same
order. Refer to AT-289, "
COMPONENTS" .
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 rings (1) excessively while install-
ing. The seal rings (1) may be deformed.
