E-3.2) Reassembly:
Outer Seal -
Clean and oil seal cavities in seal plate
(10). Lightly oil
(DO NOT use grease)
outer surface of
stationary member (12a). Press stationary member (12a)
fi rmly into seal plate (10), using a seal pusher (see parts
list- seal tool kit). Nothing but the seal pusher is to come
in contact with seal face (see Fig. 6).
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 (see parts list-seal tool kit) over motor shaft. Lightly
oil
(DO NOT use grease)
shaft, bullet and inner surface
of bellows on rotating member (12b) (see Fig. 7). With
lapped surface of rotating member (12b) facing inward
toward stationary member (12a), slide rotating member
(12b) over bullet and onto shaft, using seal pusher, until
lapped faces of (12a) and (12b) are together (see Fig. 5).
IMPORTANT! - 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 (12c) over shaft and in place on rotating
member (12b), making sure it is seated on retainer and
not cocked or resting on bellows tail. Slide retaining ring
(12d) over shaft and let rest on spring (12c). Assemble
impeller, cutter and volute as outlined in paragraph E-2.2.
Replace oil as outlined in paragraph E-1.3.
E-4) Motor, Bearing & Inner Seal Service
E-4.1) Disassembly and Inspection:
To examine or replace the motor (1), bearings (8), (3) &
(39) and Inner Seal (5), disassemble volute and impeller
as outlined in paragraph E-2.1 and disassemble outer
shaft seal as outlined in paragraph E-2.1 Drain oil from
motor and seal cavity as outlined in paragraph E-1.3.
Remove motor fan shroud (1A), fan (1B), and motor end
bell, by removing four motor bolts. Next remove washer
(37), shims (36) and bearing (8) from motor (1). Exam-
ine upper bearing (8) and replace if required. Lift motor
stator from motor rotor and then Lift motor stator from
intermediate coupling (6). To remove ball bearing (3),
remove retaining ring (7) from intermediate coupling (6)
and pull motor shaft, ball bearing (3) and inner seal (5)
from intermediate coupling (6).
