Place several drops of oil inside bellows of rotating member
(13C). Coat seal face with oil taking care not to touch or nick
it. Start rotating member (13C) squarely on shaft. Slide
mounting sleeve on shaft (see Figure 3). This sleeve assures
seal will be mounted square with seat. Press seal on shaft until
it seats using aluminum installation tool (Figure 9). Remove
mounting sleeve, install spring (13B), and spring retainer
(13A). Assemble impeller and volute as outlined in section F-5.
Replace oil per section F-4.
F-7) Upper End Bell, Motor and Bearing Service:
To examine or replace the rotor (47), stator (52) and bearings
(48) and (49), drain oil from motor as outlined in paragraph F-1.
Disassemble volute and impeller as outlined in F-5 and Seal
per F-6. Position unit upright, using blocks to avoid resting unit
on shaft. Remove cap screws (14) and washers (15) and lift
cover plate (20) from upper end bell (42). Disconnect cable
leads from thermostat (37) and terminal block (28). Remove
cap screws (41) and washers (15) from upper end bell and lift
upper end bell from motor shell (51). Remove socket head
screws (45) to remove drive end bell (46) and rotor and shaft
assembly.
IMPORTANT ! - All parts must be clean before
reassembly.
Reassembly:
When installing a new stator (52) in shell (51), be sure to use
a ring or bars that contact the stator iron only and do not cut or
press on the windings. The stator is pressed to the shoulder in
the shell.
To install bottom bearing (49) in drive end bell (46). A special
ring is required to install bearing properly. (See Figure 12 for
dimensions of this ring). Press bearing in place, this bearing
must be installed with filling notch toward rotor.
DO NOT
INSTALL THIS BEARING BY PRESSING ON INNER RACE.
Install rotor (47) in drive end bell (46) being sure retaining ring
(50) is installed on shaft. (see figure 13 for support ring).
Center inner race of bearing on support ring. Now place rotor
and shaft assembly through bearing, align it vertically and
press until rotor and shaft assembly seats in bearing. Put top
end bearing (48) on shaft with ring (see figure 14).
Press bearing in place. DO NOT INSTALL THIS BEARING
BY PRESSING ON INNER RACE. Support rotor assembly on
ring (see Figure 13) when installing top bearing so that the
pressing force is not transmitted through balls of drive end
bearing. Place Tetraseal (43) on motor shell assembly and
drive end bell (46) on and insert socket head cap screws (45)
and tighten.
To assemble switch end bell ( 42) to motor shell assembly, first
place load spring (44) onto bearing (48) and Tetraseal (43)
onto motor shell assembly. Place switch end bell (42) onto
motor shell assembly, insert cap screws (41) with lock washers
(15) into holes and tighten. Connect wiring from stator and
thermostat to terminal block (28). See Figures 15, 16 &17.
When installing a new thermostat (37), remove round head
screws (30) with lockwashers (17). Now remove cover plate
(31), cover plate gasket (32) and insulator (33).
On single phase units, remove wire ties (36) and wire nut (34)
to remove thermostat (37) from mounting stand (35).
On 1.5 & 2.2 HP three phase units, remove wires from
terminals and remove thermostat (37) and insulator (38).
On 4.5 & 6.7 HP three phase units, remove wires from
terminals and remove thermostat (37).
Replace thermostats in opposite order being sure to install
insulator (33) on top of thermostat on three phase units.
To install new diaphragm (40), first place insulator (33) into
hole, place diaphragm with side marked "PISTON SIDE"
toward outside of the motor, next place ring (39) onto
diaphragm and insert round head screws (21) with washers
(17) into holes and tighten.
When replacing power cable (25), insert cap plug protector
(26) into cover (20), place cable through cap plug and slide
cord packing washer (24) on first, then cord grommets (23) on
cord and coat with Permatex #2 before sliding into gland
opening. Place gland cover (22) onto gland opening, insert
round head screws (21) with lockwashers (17) into holes and
tighten.
Refill motor with oil per section F-4.1. Cable conductors are
now connected per Figures 15, 16 & 17, to terminal block (28).
Place conductors so they will not cross diaphragm area or
become pinched when mounting cover. Cover (20) can be
replaced, be sure gasket (27) is in place, insert cap screws
(14) with lock washers (15) into holes and tighten. The cover
section must be checked for leaks by applying 8 to 10 PSI air
pressure through pipe plug (12) opening in cover. If no leaks
are found, replace pipe plug (12).
