To Disassemble The "J" Bearing; To Assemble The "J" Bearing - Goulds Pumps JC Installation, Operation And Maintenance Instructions

To disassemble the "J" bearing

For the purpose of these instructions, assume the JC liquid end has been disassembled,
including suction disc (182), suction disc liner (100B), impeller (101), casing (100), hub disc
(184), stuffing box components, and shaft sleeve (126).
1. Pull pump coupling half or sheave from drive end of shaft.
2. Remove radial bearing slinger (123C) from shaft.
3. Remove jam nuts from adjusting studs (356A) which fasten bearing frame (228) and thrust
4. Detach thrust bearing snap ring (361) from thrust bearing housing (134A). Slide housing
5. Remove thrust bearing locknut (136) and lockwasher (382).
6. Press or pull radial bearing (168C) from shaft (122). Apply pulling force to inside bearing
7. Press or pull thrust bearing arrangement from shaft (122). For double row ball thrust
8. Do not remove radial bearing retainer (119B) from bearing frame (228). A factory press fit

To assemble the "J" bearing

1. The shaft (122), thrust bearing housing (134A) and bearings must be clean and free of

bearing housing (134A). Carefully pull the shaft (122), bearings, and thrust bearing housing
(134A) from the drive end of bearing frame (228). Support both ends of the shaft assembly
to prevent seal and bearing damage.

bearing (112C), apply pulling force to inside race only. For two-bearing thrust arrangement,
apply pulling force to inside race of thrust bearing (112D). The thrust bearing (112D), thrust
bearing collar (237), and radial bearing (112C) will be removed.

burrs.
a) Double row ball thrust bearing: (1J-4J)
1. Heat thrust bearing (112C) in 82°C | 180º F oil bath.
2. Slide thrust bearing (112C) onto shaft (122) firmly against shaft shoulder.
3. Install lockwasher (382) and locknut (136) before bearing cools. When bearing
cools to room temperature, retighten locknut and secure lockwasher tang.
b) Separate thrust (112C) and radial (112D) bearings on thrust end (5J):
1. Heat thrust bearing (112D) in 82°C | 180º F oil bath and install on shaft (122) firmly
against shaft shoulder.
2. Heat thrust bearing collar (237) in oil bath and install shaft against inner thrust
bearing inner race.
3. Heat radial bearing (112C) in oil bath and install on shaft with inner race against
thrust collar (237).
4. Install lockwasher (382) and locknut (136) before bearings cool. When bearings
cool to room temperature, retighten locknut and secure with lockwasher tang.
a) Double row ball thrust bearing:
1. Lubricate seal (332) and O-ring (496) on thrust bearing housing (134A).
2. Carefully slide housing (134A) onto shaft (122) over thrust bearing.
3. Secure housing (134A) with thrust bearing snap ring (361).
