Install ball bearing (3) in housing (1) with tooling (C) and a press. Install the bearing until it is against the shoulder in housing (1).3. Install ring (2) with tool (D). 4. Install roller bearing (5) on shaft (4) until it is against the shoulder of shaft (4).5. Put 9S3265 Retaining Compound to the inside diameter of collar (6) and on shaft (4). A pipe with a 32 mm (1 1/4 in.) inside diameter can be used in place of tool (E). 7. Install snap ring (7) with tool (D). 8. Install seal (8) with tooling (F) until it makes contact with ring (7). Install rubber washer (9) (thrower) on shaft (4). 9. Put clean water on ceramic ring (10). Install ring (10) with tooling (A) and hand pressure. Install the ring with the bevel edge down. 10. Install body (12) on housing (1). Install nuts (11) and the locks.11. Install the lock and nut on the gear end of the pump shaft. Tighten the nut to a torque of 70 N m (50 lb.ft.), and bend the tab of the lock in the nut.12. Put clean water on seal (15). Install the seal on the pump shaft with the large sealing surface against the ceramic ring. Use hand pressure only to install seal (15). If seal (15) or ceramic ring (10) have damage or wear, use new parts for replacement.13. Install washer (13) and the original shims (14) if available or shims of a thickness of 0.51 mm (.020 in.) as a place to start. 14. Install plate (16) in body (12) with the tabs of plate (16) in alignment with the notches in body (12).15. Use a micrometer, and measure the thickness of impeller (18) and the width of ring (19) to find the difference in dimensions. This difference is used to find the shims needed to get an equal amount of clearance on each side of the impeller when it is installed in the pump. Install the impeller with the threaded puller holes toward the outside.16. Install key (17) and impeller (18) on the pump shaft. 17. Install the washer and nut (21). Tighten the nut to a torque of 60 to 73 N m (44 to 52 lb.ft.). Install the cotter pin to hold the nut in position after Step 20.18. Install plate (23) in cover (20) with the tabs of plate (23) in alignment with the notches in cover (20).19. Install ring (19) and O-ring seal (22) in cover (20).20. Use a feeler gauge to check the clearance behind the impeller. The correct clearance is 0.13 0.03 mm (.005 .001 in.). Make an adjustment to the shims if necessary. 21. Install housing (24).22. Install gear (25), the washer and bolt (26). Tighten the bolt to a torque of 55 7 N m (41 5 lb.ft.). Use a punch and hammer to hit the bolt. Tighten the bolt again.23. Install cover (20).
