FIGURE 12 Pumps Service department. 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! - All parts must be clean before reassembly. F-4.2) Reassembly: Moisture Sensors, DS Models - if pump is equipped with optional moisture sensors, reassemble by applying thread compound to threads on probes (4) and install in upper seal plate (5), see Figure 20 & 21. Connect wire assemblies (53) to probes (4) with washers (46) and machine screws (45). Thermal Sensors - if pump is equipped with optional thermal sensors, use terminal connectors (52) to connect wire assemblies (51) to sensor leads. If sensor is not functioning, contact factory approved Service Center or Contact factory Service Department. Position unit upright, using blocks to avoid resting unit on shaft. Unscrew cable hex bolts (11) and remove compression flange (16a) and power cord (16). Remove snap ring (19) with flat head screwdriver. Pull the terminal block (21) out of the nousing (6) using a T -bolt or pair of pliers and a .25-20 screw in the threads of the terminal block (21). Be sure to leave slack on the motor leads connected underneath. Use needle nose pliers to pull each female connector off of the pins on the underside of the terminal block (21) see Figure 11. The unit voltage should be noted. Repeat cable and terminal block removal procedure for any control cables (56) if equipped. Remove socket head cap screws (47). Vertically lift the motor housing (6) from seal plate (5) by lifting handle (13). Inspect square ring (27) for damage or cuts. Remove the motor bolts and lift motor stator from seal plate (5). Disconnect capacitor leads from capacitor (9, single phase units). Examine bearing (25) and replace if required. if replacement is required, remove bearing (25) from motor shaft using a wheel puller or arbor press, see Figure 12 Check motor capacitor (9, single phase units) with an Ohm meter by first 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 infinity (-) then drifts back. the capacitor is good. if needle does not move or moves to infinity (-) and does not drift back, replace capacitor (9). To test the float switch (55 or 56 optional), check for continuity between the pin receptacles of the cord with the float in an "up" position. There should be no continuity with the switch in the `down" position. Replace switch (55 or 56) if malfunctioning. if moisture sensors (4, optional) are damaged, disconnect leads by removing machine screws (45) ,nd washers (46) from probes (4). Remove probes (4) from seal plate (5). To test the temperature sensor (50, optional), check for continuity between the black and white wires. If found to be defective, contact a motor service station or Barnes Bearings - When replacing bearing, be careful not to damage the rotor or shaft threads. Clean the shaft thoroughly. Press bearing (25) on the motor shaft, position squarely onto the shaft applying force to the inner race of the bearing only, until bearing seats against the retaining ring (24) (included with motor). Motor - Slide lower bearing (25) and motor shaft squarely into the seal plate (5) until bearing seats on the bottom. Place stator over rotor, lining up motor bolts with holes in seal plate (5). Position capacitor (9, single phase units) so that it will lay on the opposite side of the cable entry bosses of the motor housing (6). Reconnect capacitor leads. Torque motor tie bolts to 17 in -lbs. Set square ring (27) in groove on seal plate (5). F-4.3) Wiring Connections: Check power cables (16) and control cable (56, if used), for cracks or damage and replace if required (see Figure 14). Make internal wiring connections which are independent of the terminal block as shown, using connectors (48) and wire assemblies (49) and (63) as required. Do not use wire nuts. Slip motor leads and groud wire through fiberglass sleeve. Lower motor housing (6) down onto seal plate (5) while aligning holes and stringing motor leads through the cable entry bore(s). (Slipping cords inside a 1 ft. length of .5" conduit makes this easier). Place socket head cap screws (47) through seal plate (5) into motor housing (6) and torque to 60 in -lbs. 14 COMPRESSION FLANGE ALIGNMENT MARK ON CORD MUST ALIGN V1.17H THE ALIGNMENT PARK ON TERMINAL FLOCK FOR PROPER ASSEMBLY
