d) Install the two socket head cap screws that hold the upper and lower halves of the sleeve bear-
ing (117) together.
9.
Install the inboard floating oil seal (123G).
10. Install the bearing spacer (443V) and thrust collar key (282).
11. Install the thrust collar onto the shaft (122) using the thrust collar key (282).
12. Install the inboard and outboard ends of the tilt pad bearing (280) between the thrust collar.
13. Install the thrust collar nut (283) onto the shaft (122). Utilize the flats on the thrust collar nut (123) to
tighten against the thrust collar. Note the thrust collar nut (283) is threaded to tighten against rota-
tion. For CCW pump rotation (when viewed by the drive end) the thrust collar nut (283) is left hand-
ed. For CW rotation, the thread is right hand.
14. Install the floating oil seal (123G) to the outboard end.
15. Install the upper half of the bearing housing (134A).
16. Install the two taper pins to line up the upper and lower halves of the bearing housing (134A).
17. Install the hex cap screws that connect the upper and lower halves of the bearing housing (134A).
18. Install new O-ring (412M) onto the filler plate (441A).
19. Install the shim pack (390C/M) onto the filler plate (441A).
20. Install the filler plate (441A) into the bearing housing (134A). Tighten the hex cap screws between
the bearing housing (134A) and the filler plate (441A).
21. If pump has been supplied with axial proximity probes, screw the axial proximity probes into the filler
plate (441A). Do not tighten the axial proximity probes all the way down until they come into contact
with the thrust collar. The axial proximity probes should be set at .050” away from the thrust collar.
NOTICE:
If the axial proximity probes are touching the thrust collar during operation, the axial proximity
probes will break and fill the bearing housing with debris resulting in premature bearing failure.
22. Use the hex cap screws (370W) to install the cover filler plate (113J). Make sure the cable from the
axial proximity probe is exiting through the pipe tap connection on the cover filler plate (113J). There
is one cover filler plate (113J) on each side of the bearing housing (134A).
23. If the pump was supplied with a main shaft oil pump (219), install the coupling key, coupling hub,
and spacer to the pump shaft (122). If the pump was not supplied with a main shaft oil pump go to
step 26.
24. Install a new o-ring (412Y) onto the oil pump adapter (318A). Use the hex cap screws (370N) to
install the oil pump adapter (318A) to the filler plate (441A).
25. Use the hex cap screws (370L) to install the main shaft oil pump (219) to the oil pump adapter. En-
sure the coupling half on the main shaft oil pump (219) is inserted into the coupling spacer.
26. If the pump was not supplied with a main shaft oil pump (219), install a new o-ring (412Y) onto the
adapter cover (119C). Use the hex cap screws (370N) to install the adapter cover (119C) to the filler
plate (441A).
6.6.8 Assemble the radial end (sleeve/tilt pumps)
1.
Install the cartridge mechanical seal (383) on the shaft (122) and align the mechanical seal pilot
with the seal chamber bore of the casing. Install the mechanical seal studs (353) and hex nuts
(355).
NOTICE:
Do not set the mechanical seal sleeve set screws at this time; endplay must be checked first or
damage to the seal faces could occur.
2.
Install the inboard labyrinth seal (333A).
