Rotating torque: 0.2 Nm (2.2 inch lbs.) or less.

2. Remove suction port union, as follows:
a. Remove the bolt.
b. Remove the O-ring from the union.

3. Remove pressure port union, flow control valve and spring. Remove the O-ring from the union.
4. Remove rear housing. Remove the two bolts.
5. Remove cam ring, vane pump rotor and ten vane plates.

NOTICE: Be careful not to drop the vane plates.

6. Remove two straight pins.
7. Remove gasket.
8. Remove vane pump shaft with bearing, as follows:
a. Using snap ring pliers, remove the snap ring from the front housing.





b. Wind vinyl tape on the serrated part of the shaft.
c. Using a press, press out the shaft with the bearing.

9. Remove side plate and wave washer, as follows:
