DISASSEMBLY. (Cont)
m.
Using arbor press, remove two bearings (24) and (26) and one bearing lockring (27).
n
Using arbor press, remove centrifugal switch (28) from shaft of rotor (25).
o
Remove four screws (29) and capacitor cover (30).
NOTE
Tag capacitor wires before removal.
p.
Disconnect capacitor leads T10 a d remove capacitor (31) and gasket (32).
n
CLEANING.
WARNING
Compressed air can blow dust into the eyes. Wear eye protection. Do
not exceed 30 psi (207 kPa) air pressure.
a.
Scrape loose paint from fan cover, shell, and pump end shields. Prime and paint as necessary.
b.
Using compressed air, blow dust and grit from stator and rotor. Wipe rotor with clean rag.
c.
Wipe bearings with clean rag if grease is dry or dirty.
INSPECTION.
a.
Inspect leads and windings of stator for evidence of cracked or burned insulation.
Replace shell if stator is
damaged.
b.
Inspect rotor for loose or burned conducting bars. Replace as required.
c.
Inspect bearings for wear. Replace as required.
d.
Inspect end shields for cracks. Replace as required.
e.
Using multimeter set to OHMS X1 scale, connect one test lead to each set of motor leads.
f.
If multimeter indication is not 0 ohm, replace stator.
g.
Set multimeter to OHMS X1000 scale. Connect one lead to stator housing. Connect other lead to each set of
motor leads in turn.
h.
If multimeter indication is not infinity for each motor lead, replace stator.
i.
Connect multimeter leads to capacitor leads. If multimeter indication does not indicate resistance, increasing to
more than 50K ohms, replace capacitor.
j.
Set multimeter to OHMS X1 scale. Connect leads to stationary switch leads. If multimeter indication is not 0 ohm,
replace stationary switch. If multimeter indication is 0 ohm, but motor started only by hand during test, replace
centrifugal switch.
