10. Remove O-ring (90) from front cover (1) if it did not come off with last housing removed.
11. Remove socket head capscrews (75) and bearing retainer (70) with lip seal (32), where applicable.
12. If lip seal (32) is included in the bearing retainer (70) and it is to be replaced, remove it from the bearing retainer
(70) and discard.
13. Remove socket head capscrews (42).
14. Reinstall bearing retainer (70) and socket head capscrews (75).
15. Remove shaft (6) from front cover (1). Bearing housing (9), seal spacer (if applicable) (74), ball bearing (31),
bearing retainer plate (70), capscrews (75) and O-ring (40, 80) will come off with shaft as an assembly.
CAUTION
ATTENTION
Be sure that all gear keys (13) are removed before removing shaft (6). If not, front cover
(1) face will be damaged.
CAUTION
ATTENTION
Handle ‘shaft/bearing housing’ assembly with great care since any significant cocking of
bearing housing (9) assembly relative to shaft (6) could damage ball bearing (31) or
mechanical seal (51). If shaft (6) is to be set down on a work surface, it should not be
allowed to rest on bearing housing.
16. Remove O-rings (40 and 80) from bearing housing (9).
NOTE:
If neither ball bearing (31) nor seal (51) are to be replaced or inspected, disassembly is complete. If either
of these components are to be replaced or inspected for any reason, proceed as below:
17. Place inboard face of bearing housing (9) on the clean, smooth surface of an arbor press with coupling end facing up.
18. Remove socket head capscrews (75) and bearing retainer (70).
19. Remove ball bearing snap ring (33).
20. Press shaft (6) out of bearing housing (9) by pushing squarely on coupling end of shaft (6). Rotating member of
seal (51) and its seal spacer (if applicable) (74) will remain on shaft while ball bearing (31) and stationary member
of seal (51) will remain in bearing housing (9).
CAUTION
ATTENTION
Be sure to hold onto shaft (1) when pressing it out of bearing housing (9).
CAUTION
ATTENTION
Take extreme care during this step to avoid damaging seal faces.
21. Remove ball bearing (31) from bearing housing (9) by lightly tapping it out with brass rod from inboard side.
CAUTION
ATTENTION
Be careful not to damage stationary face of seal (051) with brass rod.
NOTE:
If mechanical seal (51) is not to be replaced, disassembly is complete. Take care to prevent damage to
seal components. If mechanical seal (51) is to be replaced, proceed as below.
22. Press stationary part of mechanical seal (51) out of bearing housing (9).
CAUTION
ATTENTION
Be careful not to damage stationary face of seal (51) when pressing it out.
