Removing a Stuck Electric Motor from a Gould Irrigation Pump

A homeowner unbolted a burned-out electric motor from a Gould irrigation pump but cannot separate the motor from the pump housing. No latch pin is visible; corrosion is the likely culprit.

Steps to Free the Motor

1. Tap the motor flange gently with a rubber mallet, working around the circumference to break the corrosion bond.
2. Apply penetrating oil (e.g., PB Blaster) to the joint and let it soak for several hours.
3. Use a puller or pry bars evenly if tapping doesn’t work, but avoid damaging the pump housing.
4. If the pump is installed outdoors, check for additional corrosion from weather exposure.

Provide the pump’s model number and whether it’s installed indoors or outdoors for more specific guidance. If the motor shaft is seized, the pump may also need bearing replacement.
