ASSEMBLY PROCEDURES:

11. REPLACE MECHANICAL SEAL



Clean the shaft sleeve [70] surface, ensuring all the former

seal elastomer pieces have been removed. Inspect for

damage. Replace if necessary. (See separate instructions

for removal of the shaft sleeve [File No. 6042.25]). Inspect

the water slinger [39] and replace if damaged



Install a new seal seat [60] in the adapter cavity, being

sure the lapped (polished) side of the insert is facing up.

Ensure that the cavity has been thoroughly cleaned. Lubri-

cate the seat O-ring or L-cup with a small amount silicon

or glycerine lubricant and press down, straight and even,

into the cavity. Do not press the seat in with bare fingers,

use a clean cloth or the cardboard disc typically supplied

with the seal. Contamination of the polished and lapped

seat face could cause leakage. If the adapter was re-

moved from the motor, replace now, taking care that the

seal seat is carefully guided over the motor shaft.



Lubricate the inside of the seal rotating assembly [62] with

a small amount of silicon or glycerine lubricant and slide

onto the shaft sleeve [70] with a twisting motion, carbon

face first, until the carbon face is pressed firmly against

the seal seat [60]. Pressing on the seal rotating assembly

metal parts, with a screw driver, all the way around the

seal, will ensure that the faces are mated properly. Re-

move the spring retainer from the seal spring and place

the seal spring over the seal rotating assembly. Series

4360D and 4380 units with frame 56C motors will have a

shaft extension in place of an extended JM/JP shaft. This

should be treated in exactly the same manner as de-

scribed above for seal replacement.

12. REPLACE PUMP IMPELLER



Install the shaft sleeve spacer [71] and impeller key on the

shaft and place the seal spring retainer onto the impeller

hub register. Slide the impeller in place on the motor shaft.



Take care and ensure that the seal spring is kept in place

on the seal rotating assembly and fits well into the retainer

on the impeller hub.

13. TIGHTEN IMPELLER CAPSCREW



It is good practice to replace self locking screws, once

removed. Install the impeller capscrew and washer [83 &

86]. Hold the impeller the same way as when the cap-

screw was successfully loosened (Bar or screw driver

placed carefully between the impeller blades) and tighten

the capscrew with a socket wrench.

14. INSTALL NEW CASING GASKET



Insert new casing gasket [101] into the gasket cavity in

the casing.

15. LOWER ROTATING ASSEMBLY INTO PLACE



The rotating assembly (Motor, adapter and impeller

combination) may now be lowered into place in the

casing.

16. CASING CAPSCREWS



The casing capscrews [104] are now installed and evenly

tightened with a wrench. Tighten the capscrews a little at

a time, diagonally across the casing, to assure even

gasket pressure.

Replace the flush/vent tubing assembly

17. ISOLATION VALVES



Replace the casing drain plug and open the suction and

discharge isolation valves.

18. MOTOR WIRING



The motor conduit and its wiring are now replaced. If the

motor is new, double check that the voltage and rpm are

identical to the original motor.



Be sure to check rotation of the motor after rewiring if the

motor is three phase and correct if necessary, by switch-

ing any two lead wires.



Ensure that the pump is filled with water before operating

to check rotation.

19. CONDUIT BOX COVER



The conduit box cover is replaced after checking the mo-

tor rotation. The pump may now be placed in operation.
