We use Little Giant Pumps for our animal tanks. This pump looks sturdy, but it often fails if you don't lubricate it like every 6 months or so like a Harley Davidson. You have to baby-sit it all time. Just like HD, this Little Giant is proudly made in the USA. By the way, I saw Georgia Aquarium uses Iwaki pumps, which are more like Honda in reliability compared to HD. Today, I had to shut down one of our tanks to replace the filter. Then, this little giant failed to restart.
So I had to restore it.
Here’s the tricky part: you need a flat-head screwdriver and a hammer to remove this small flip mechanism.
Components include: the water propeller, motor, inlet-outlet section, main shaft with fan, end cover, and magnet ring.
Inside the motor, everything needs a thorough cleaning.

cool blog! i cited your research on the myogenic heart beat in crustaceans in a lab report just now. thanks for your science!!
Awesome!!The pictorial representation helps me a lot to understand clearly about dissecting the little giant pump which made it so easy to lube the pump.Thank you so much dude.
Thank you two for comments.
For little giant pump, Dripping oil into the holes on both ends of the motor does not help at all. I lately found that the shaft gets stiff near the propeller magnet outside of the motor unit. Just spray there with KURE CRC5-56. You may not need to disassemble it.
