Check motor capacitor (3, 1 phase units) with an Ohm meter
by fi rst grounding the capacitor by placing a screwdriver across
both terminals and then removing screwdriver. Connect Ohm
meter (set on high scale) to terminals. If needle moves to infi nity
(∞) then drifts back, the capacitor is good. If needle does not
move or moves to infi nity (∞) and does not drift back, replace
capacitor (3). Inspect motor winding for shorts and check
resistance values. Check rotor for wear. If rotor or the stator
windings are defective, the complete motor must be replaced.
IMPORTANT ! - Handle seal parts with extreme
care. Do Not scratch or mar lapped surfaces.
Seal -
Remove rotating member (38a), spring (38c) and retain-
ing ring (38d) from shaft. (See Figure 5). Examine all seal parts
and especially contact faces. Inspect seal for signs of wear
such as uneven wear pattern on stationary members, chips
and scratches on either seal face.
DO NOT
interchange seal
components, replace the entire shaft seal (38). If replacing seal,
remove stationary (38a) from seal plate (24) by prying out with
fl at screwdriver.
Bearing -
Examine bearing (39) and replace if required. If re-
placement is required, remove bearing (39) from motor shaft us-
ing a wheel puller. Washer (28), retaining ring (29) and conduit
bushing (30) can now be removed from motor shaft.
IMPORTANT ! - All parts must be clean before
reassembly.
F-3.2) Reassembly:
Bearing -
When replacing bearing, be careful not to damage
the rotor or shaft threads. Clean the shaft thoroughly. Slide
conduit bushing (30) and washer (28) over motor shaft. Insert
retaining ring (29) into groove on shaft. Apply adhesive com-
pound to the shaft and press bearing (39) on the motor shaft,
position squarely onto shaft applying force to the inner race of
the bearing only, until bearing seats against retaining ring (29).
