IMPORTANT ! - DO NOT hammer on the seal
pusher- it will damage the seal face.
Make sure the stationary member is in straight. Slide a bullet
over motor shaft. Lightly oil
(DO NOT use grease) shaft, bullet
and inner surface of bellows on rotating member (28b) see
Figure 9. With lapped surface of rotating member (28b) facing
inward toward stationary member, slide rotating member over
bullet and onto shaft, using seal pusher, until lapped faces of
(28a) and (28b) are together (see Figure 8).
It is extremely important to keep seal faces clean during
assembly. Dirt particles lodged between these faces will cause
the seal to leak. Place spring (28c) over shaft and in place on
rotating member (28b), making sure it is seated on retainer and
not cocked or resting on bellows tail. Slide retaining ring (28d)
over shaft and let rest on spring (28c). Replace snap ring (32)
in groove of shaft. Set square-ring (27) in groove on outer seal
plate (29) and place outer seal plate (29) onto inner seal plate
(5). Replace socket head cap screws (64) and torque to 60 in-
lbs.
Outer Seal (All Units) - Press stationary member (28a) fi rmly
into outer seal plate (5, or 29 on DS Units) as described above.
Slide rotating member (28b) onto stationary member using seal
pusher as described above. Place spring (28c) and retaining
ring (28d) onto rotating member (28b). Assemble impeller and
volute as outlined in paragraph F-2.2. Replace oil as outlined
in paragraph F-1.4.
F-4) Motor and Bearing Service
F-4.1) Disassembly and Inspection:
To examine or replace the motor (7), capacitor (9, single phase
units), controls (56, optional), and bearing (25), drain oil from
motor as outlined in paragraph F-1.1. Disassemble volute and
impeller as outlined in paragraph F-2.1 and disassemble shaft
seal as outlined in paragraph F-3.1.
Position unit upright, using blocks to avoid resting unit on
shaft. Unscrew cable hex bolts (11) and remove compression
fl ange (16a) and power cord (16). Remove snap ring (19)
with a fl at head screwdriver. Pull the terminal block (21) out
of the housing (6) using a T-bolt or a pair of pliers and a .25-
20 screw in the threads of the terminal block (21). Be sure to
leave slack on the motor leads connected underneath. Use
needle nose pliers to pull each female connector off of the pins
on the underside of the terminal block (21) see Figure 10. The
unit voltage should be noted. Repeat cable and terminal block
removal procedure for any control cables (56) if equipped.
Remove socket head cap screws (47). Vertically lift the motor
housing (6) from seal plate (5) by lifting handle (13). Inspect
square ring (27) for damage or cuts. Remove the motor bolts
and lift motor stator from seal plate (5). Disconnect capacitor
leads from capacitor (9, single phase units). Examine bearing
(25) and replace if required. If replacement is required, remove
bearing (25) from motor shaft using a wheel puller or arbor
press, see Figure 11.
