(4) Test capacitor using a multimeter. Isolate capacitor and discharge it by shorting across its terminals.
Connect test probes across capacitor terminals with meter set at its highest resistance range. If there is no
indication, the capacitor has an open, if there is a steady nearzero reading, the capacitor has a short, and if the
needle flicks to a near-zero reading, then slowly moves to a near-infinity reading, the capacitor is good. Verify
this indication several times as it happens very quickly.
g. Repair or Replace.
(1) Replace all gaskets, seals, and Wrings.
(2) Replace all damaged nuts, bolts, screws, washers, shaft keys, Woodruff keys, and wavy washers.
(3) Replace capacitor, if unserviceable.
(4) Replace damaged, worn, or unserviceable ball bearing assemblies.
(5) Repack serviceable clean bearings with fresh bearing grease.
(6) Deburr rotor shaft and remove any spot-weld residue by buffing with fine emery cloth.
(7) Straighten bent or dented cooling fan blades and ventilation louvers.
(8) Replace damaged, unrepairable, or unserviceable motor casing assembly.
(9) Send all unserviceable components of chemical feed pump motor assembly to next higher level of
maintenance.
h. Reassembly. (Figure 3-9) (ARMY)
(1) Connect two wire clips of capacitor (26) and install capacitor (26) on motor casing (27).
(2) Hold capacitor cover (25) in place on motor casing (27).
(3) Install two screws (24) through capacitor cover (25) and motor casing (27).
(4) Connect two wire clips to stationary switch (23) and hold stationary switch (23) in place in motor
casing (27).
(5) Install two screws (22) through stationary switch (23) and motor casing (27).
(6) Install centrifugal mechanism (21) on rotor shaft (15).
(7) Install bearing snap ring (19) and snap ring (20) on rotor shaft (15) in front of centrifugal mechanism
(21).
(8) Press fan-end bearings (18) on rotor shaft (15).
