(1) Following general safety and electrical instructions, disconnect the power to the motor and
remove power cords.
(2) Loosen and remove the four motor bolts.
(3) Attach a strong sling or chains to the motor lifting lugs or eyebolts to ensure that the motor is
balanced when lifted vertically.
(4) Slowly lift the motor off the pump assembly being careful to retain the shaft key. If the motor
does not slide easily out of the coupling do not raise the pump into the air, dropping the pump
end can cause damage. Fix the pump base to the floor or bench and lift motor again.
Section 7 – General Pump Maintenance and Disassembly Instructions
Disassembly Tips
• Before beginning, it is recommended that tape or some other method of marking be used to
make markings on the outer “can” assembly to indicate orientation, such as “top” and “bottom”.
• Next, make corresponding alignment markings that indicate where the bottom of the can and
lower casing assembly meet. Also make another marking to indicate where the top of the can
and lower portion of the cast iron motor support meet.
• Always inspect for damage of other components and clean any debris that you may find during
maintenance procedures.
• Cross sectional views of the pumps are a good reference for these procedures and can be
found starting on page 22.
