Always turn the power off at the electrical service entrance fuse or breaker box, to p revent possible electric shock. To prevent electrical shock when touching the motor, be sure windings and capacitor are securely grounded to the ground term i n a l which should be used in conformity with local codes. • 6.Inspect the motor windings for continuity. 7.If voltage is proper at terminals and the motor is cold, remove the motor and take it to a A.O.

Neptune and Flex-48 products are designed in a 48 frame shell and are 5.6 inches in diameter. • 4.T Y P E: The electrical design of the motor is shown by its type. Smith uses “CX” to identify its switchless design. Other codes include “CS” for c a p a c i t o r- s t a rt, “S P” for split-phase and “CP” for capacitor start / capacitor run.

• As a rule, if it’s necessary to replace one bearing, replace the other as well. Use only A.O. Smith bearings with the proper part number for the motor that you’re working on.

Smith bearings are lubricated and re q u i re no furt h e r. • MOTOR TROUBLESHOOTING bearings because this could damage the motor and cause a re t u rn service call. 1.TURN THE POWER OFF 2.Remove the cover from the motor and disconnect the electrical supply leads from the terminal board. Then remove the electrical cable or conduit from the end frame. • 6.Remove the bearing(s) from the motor shaft, following these steps as necessary: a )Remove shaft collars used to secure bearings. D o n ’t reuse a bearing that is removed from the shaft.

• MOTOR TROUBLESHOOTING capacitor using an ohmmeter (see “ Troubleshooting A Capacitor” page 23). 5.Rotate the motor shaft. If you hear a grinding sound, disassemble the motor and check: the conditions of bearings, a rotor rubbing the stator, c o rrosion, a cracked frame, clogged fan or o b s t ruction(s). • 1.Mounting, motor coupling and brackets. Tighten loose nuts, bolts or set scre w s. 2.If a noticeable drag is present, check the bearings and bearing load spring.

Triple Seal protection is a robust design that protects the pump end bearing on both the outboard and inboard facing seal of the bearing using three distinct sealing systems (See image below). While Triple Seal protection is designed to protect the pump end bearing from general water ingress, dust and debris, it is not designed to protect against leaky pump seals, constant spray from irrigation systems, or other extraneous conditions. Triple Seal protection is another line of defense from moisture intrusion into the pump end bearing system. Features • Hybrid end frame design • Access to PCB terminal board • Voltage change device • Definitive shaft access (7/16” wrench) • Auto protector • UL 1081 design • 203 Bearings Both Ends • Sealed Ball Bearings • NEW Triple Seal™ Protection on pump-end bearing • 60 Hz • 50°C Ambient • Rotation: CCW Pump End • 303 Stainless Steel Threaded Shaft • Open Dripproof Resources.
