INSPECTION
Oil Pump Housing, Oil Pump Cover, Inner Gear and Outer Gear
●Check for wear or damage.
Side Clearances
●Measure side clearance of inner and outer gears in at least four
places around each outside edge. Maximum measured values
should be within specified positions.
●If clearance is less than standard, select inner and outer gear as
a set so that clearance is within specifications.
●If clearance is more than standard, replace whole oil pump
assembly except oil pump cover.

3. Install inner and outer gears on oil pump housing.
●Take care with 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 3 5 , "
