ASSEMBLY





1. Lubricate new drive shaft seal with power steering fluid (GM Spec. 9985010).
2. Install new drive shaft seal into pump housing using a suitably sized socket as a driver.





3. Install thrust plate and pump motor onto drive shaft.
4. Install new shaft retaining ring onto drive shaft.
5. Install drive shaft/rotor/thrust plate assembly into housing.
6. Install pump ring dowel pins into pump housing through thrust plate.





IMPORTANT: The pump ring face has an indentation on one side near dowel hole. The ring must be installed with indentation facing up. If the ring is installed upside down, the pump will not function.

7. Install pump ring (with holes correctly positioned onto dowel pins) into housing.
8. Install vanes into pump rotor. Vanes have a radius at both ends and may be installed in either direction.
9. Lubricate new pump housing 0-ring with power steering fluid and install into groove in housing.
10. Install pressure plate dowel holes with dowel pins and install plate into housing.





11. Position pressure plate spring against pressure plate. The spring may be installed in either orientation.
12. Lubricate new end cover 0-ring with power steering fluid (GM Spec. 9985010) and install onto end cover.
13. Lubricate outer edge of end cover with power steering fluid (GM Spec. 9985010).

IMPORTANT: Make sure retaining ring is fully seated in housing groove. If difficulty is encountered, use a press as shown or a C-clamp (one side on end cover, the other on pump drive shaft) to depress end cover, easing installation to retaining ring. Make sure to insert a piece of wood (or other protective material) between C-clamp and pump drive shaft.

15. Install retaining ring into groove in pump housing, with ring opening near, but not across, access hole in housing.
