Remove bearing retainer (22). Remove the bearing from housing (15) with Tool (E) and a press.17. Remove bearing race (23) with Tool (G).Assemble Sea Water Pump (Earlier Marine Engine)
1. Install the bearing race in housing (1) with Tool (B). Install bearing until it is against the shoulder in housing (1). 2. Install the double roller-bearing (2) in housing (1) with Tool (C) and a press. Install the bearing until it is against the shoulder in housing (1). 3. Install single roller bearing (4) on shaft (3) until it is against the shroud of shaft (3).4. Put 9S3265 Retaining Compound to the inside diameter of collar (5) and on shaft (3). Install collar (5) until it makes contact with bearing (4). Remove any excess compound. 5. Install retainer (6) on housing (1) to hold the double roller bearing (2) in position.6. Install shaft (3) and bearing (4) in housing (1) as a unit. Be sure that shaft (3) is in alignment with the bearing (4) is also in alignment with it respective outer race. 7. Install snap ring (7) with Tool (D). 8. Install seal (8) with Tool (F) until it makes contact with snap ring (7). Install rubber washer (9) (thrower) on shaft (3). 9. Put clean water on the ceramic ring (10). Install ceramic ring (10) with Tool (A) and hand pressure. Install the ring with the bevel side down. 10. Install body (13) on housing (1). Install nuts (15) and locks.11. Install the spacer, lock and nut on the gear end of the pump shaft. Tighten the nut to a torque of 95 to 11 N m (70 to 80 lb ft) and bend the tab of the lock in the groove of the nut.12. Put clean water on seal (16). Install seal (16) on the pump shaft with large seal surface against the ceramic ring. Use hand pressure only to install seal (16). Make a replacement of both seal (16) and ceramic ring (10) if either is damaged or worn.13. Install washer (11) on the pump shaft.14. Install plate (17) in body (13) with tabs (12) in alignment with the notches in body (13).15. Install the O-ring seal around ring (14). 16. Install the original shims (20) if available or shims of a thickness of 0.51 mm (.020 in) as a place to start.17. Use a micrometer and measure the thickness of the impeller (18) and the width of ring (14) to find the difference in dimensions. This difference is used to find the shims needed to get the same amount of clearance on each side of the impeller when it is installed in the pump.18. Install key (19) and impeller (18) on the pump shaft. Install the impeller with the threaded puller holes toward the outside. 19. Install the washer and nut (22). Tighten the nut to a torque of 180 2 N m (133 15 lb ft). Install the cotter pin to hold the nut after Step 20.20. Use a feeler gauge to check the clearance behind the impeller at four locations the same distance apart. Use the average of the four measurements. The correct clearance is 0.20 0.03 mm (.008 .001 in). Make an adjustment to the shims if necessary.21. Install plate (21) in cover (24) with the tabs of the plate in alignment with the notches of cover (24).22. Install ring (14) and O-ring seal (23) in cover (24). 23. Install housing (26) on the pump.24. Install gear (27) and the washer and bolt (28). Tighten the bolt to a torque of 55 7 N m (40 5 lb ft). Use a hammer and punch and hit the bolt. Tighten the bolt again to the same torque.25. Install cover (24) and clamp (25) on the pump.End By:a. install sea water pumpDisassemble & Assemble Sea Water Pump (Later Marine Engines)
