If your pool pump motor is exposed to the elements there is a good chance that the motor label may become too faded to read. When that pump motor then fails it can be difficult to find a replacement without model numbers listed on the label. If this is the case there are a couple of ways to identify your pool pump and motor to find a match.
The easiest way to determine your pump model is by finding the part number on the strainer lid. The lid may be unique to your style pump in that case you already have part of the equation. With that information you would only require the horsepower of the pump to determine a suitable motor match. In the meantime you can use the model information to search for any other parts of the pump you may need. Perform the strainer lid part number inquiry through Inyo's engine; this will bring up any results to be had. If the lid is not unique and is a universal part for a manufacturer's entire line of pumps then you will have to do more digging. Specifically we will need to remove the impeller. Information of this part will provide the make, model, and HP of your pump motor.
The next few steps are a brief overview of how to get to the impeller. We suggest reading the more extensive step by step guide on this operation if you are inexperienced: How To Replace A Pool Pump Impeller. We will not be removing the impeller so you may skip those parts of the guide.
Locate the impeller part number located on its face. This piece of info is the key to finding a motor replacement. Using Inyo's search engine input this part number and the result should the part which will be linked to info such as the manufacturer, pump model, and horsepower. With this information in hand you can then locate your motor number through our pump motor section.
Replace the four bolts back into place. If bolts were numbered 1 through 4, replace bolts in this sequence - 1, 3, 2, and 4 - to ensure that the motor is set properly inside the housing. Loosely tighten bolts in this sequence, then go back and tighten them down again in this sequence. If pump has 6 bolts, replace bolts in this sequence - 1, 3, 5, 2, 4, 6
