My pool pump motor has started running louder than usual. Does anyone know if there are grease points on pool pumps, or are the bearings usually sealed? Wondering if I can lubricate it to quiet things down. Any advice?

It’s likely sealed bearings. When the shaft seal wears out, water can get in and damage the bearings. I rebuilt my pump last fall. It wasn’t too hard, and now it’s much quieter.

Vs is much more efficient. I’d definitely consider it before repairing a single-speed.

@AquaAdventurer Can I swap a single-speed motor for a variable-speed motor, or do I need to get a new pump?

@Umbrielle You can just replace the motor. Check the frame type (likely 56y or 48y) and the power rating of your old motor. Then, find a new motor with the same frame type and at least the same power rating.
Note: If you have a 56y frame motor, you can replace it with either a 56y or 48y. The 48y will come with a spacer to match the height of the 56y, even though the 48y is a smaller diameter. The flange holes will line up.

Sealed. If it’s getting louder, you might need to have it rebuilt or consider upgrading to a VS model.

@BreaststrokeBuff With a variable speed pump, why upgrade?

@Umbrielle Whether to repair or replace the pump depends on how old it is and its condition.
Most single-speed pumps and replacement motors are banned by US DOE regulations. A variable speed (VS) pump is more efficient and uses less power, even when running at full speed. It can pay for itself in about 2 years.

@Umbrielle If your pump is still working, don’t upgrade it. Instead, take it to a local electric motor repair shop for a rebuild or repair. Don’t ignore any noise—fix it soon to avoid worse damage.
