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 "COMPONENTS".
