d. Scrape loose paint from fan cover, case and pump end plate. Prime and paint as necessary.
INSPECTION.
a. Inspect leads and windings of stator in case for evidence of cracked or burned insulation. Replace as
required.
b. Inspect rotor shaft for loose or burned conducting bars. Replace as required.
c.
Inspect bearings for wear. Replace as required.
d. Inspect end plates for cracks. Replace as required.
e. Using multimeter set to OHMS X1 scale, connect test leads to pairs of motor lead sets: 4, 5, and 9 to 1
and 7:1 and 7 to 2 and 8; 1 and 7 to 3 and 6; and 2 and 8 to 3 and 6.
f.
If multimeter indication is not 0 ohm for each pair of windings, replace stator.
g. Set multimeter to OHMS X1000 scale. Connect one lead to stator housing. Connect other lead to each
motor lead in turn.
h. If multimeter indication is not infinity for each motor lead, replace stator.
ASSEMBLY.
NOTE
Booster pump electric motor and distribution pump electric motor are
assembled the same. Booster pump electric motor is shown.
a. Pack two bearings (19) and (22) and use arbor press to install bearing (19) on short end of rotor shaft
(13).
b. Using arbor press, install bearing (22) on plate (20).
c.
Install retainer ring (24) and two screws (21) on plate (20).
CAUTION
Stator wiring inside case can be damaged by rotor shaft if rotor shaft is not
installed carefully. Guide rotor shaft carefully while installing it.
d. Insert rotor shaft (13) through case (16).
e. Position plate (20). Align mark made during disassembly with mark on case (16.
)
f.
Install wavy washer (17), shim (18) in plate (15).
g. While holding plate (20) aligned on one end of case (16), position plate (15) on other end. Align mark
made on plate during disassembly with mark on case.
