| NOTICE |
|---|
Do not let bearing housing (15) fall when it is removed from drive body (13). |
10. Use a press to remove bearing housing (15) and pump shaft (16) from drive body (13). Remove seal (17).
NOTE: Make a replacement of both seal (17) and the ceramic rings if either is damaged or worn.
11. Remove the ceramic ring from drive body (13) with tooling (C) and a press.
12. Remove the water thrower from pump shaft (16). Remove seal (18) with tool group (H).
13. Remove snap ring (19) with tool (E).
14. Bend back the lock from nut (21). Remove nut (21) with tool (F). Remove the lock.
15. Remove spacer (20).
16. Remove pump shaft (16) from bearing housing (15) with a press. Do not let the pump shaft fall as it is removed.
17. Remove the bearing from pump shaft (16) with a press.
18. Remove bearing retainer (22). Remove the bearing from bearing housing (15) with tooling (G) and a press.
19. Put 2P2506 Thread Lubricant on the threads, then install the washer and nut (24). Tighten the nut to a torque of 60 to 70 N·m (44 to 50 lb ft). Do not exceed the minimum recommended torque when aligning the nut to install the cotter pin. Install the cotter pin to hold the nut.
Assemble Sea Water Pump
1. Install the bearing race in housing (1) with tooling (B). Install the bearing until it is against the shoulder in housing (1).
2. Install double roller bearing (2) in housing (1) with tooling (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 shoulder of shaft (3).
4. Put 9S3265 Retaining Compound on 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 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 bearing (2) and bearing (4) is also in alignment with its respective outer race.
7. Install snap ring (7) with tool (D).
8. Install seal (8) with tooling (F) until it makes contact with snap ring (7). Install rubber washer (9) (thrower) on shaft (3).
