4. Remove the dowel pins (469J) that hold the lower half of the bearing housing to the casing
flange.
5. Loosen the nuts (427J) that hold the bearing housing in place.
The bearing housing will rest on the studs.
6. Rotate the lower half of the sleeve bearing (117) around the shaft (122) in order to remove
it from the lower bearing housing.
7. Remove the nuts (427J).
8. Remove the lower half of the bearing housing (134A) using a crane. Remove the studs
(371T).
9. Remove the thrust locknut (136) and the lockwasher (382) from the shaft.
10. Remove the oil ring sleeve (443B).
11. Use a bearing puller tool in order to remove the thrust bearing (112A) from the shaft.
The inner race on this inner duplex bearing will likely remain on the shaft when the bearing
is pulled. Remove this inner race by applying heat. Do this away from the pump site.
WARNING:
The pump may handle hazardous and/or toxic liquids. Trapped or undrained liquid can cause explosions
when heat is applied. Never apply heat at the pump site for this reason. Heat can also distort machined
surfaces.
S group pumps have a bearing spacer (217).
12. Remove the two oil rings (323) located at the sleeve bearing.
13. Remove the labyrinth seals (333A).
Disassembly of the sleeve/Kingsbury bearing arrangement
If your pump is equipped with the rarely-supplied sleeve/Kingsbury bearing arrangement, refer
to the topics Disassemble the radial end (sleeve/ball bearing pumps) and Disassemble the
thrust end (sleeve/ball bearing pumps) for sleeve bearing disassembly.
Also see the instructions provided by Kingsbury for specific information regarding this tilting-
pad hydrodynamic bearing.
