OEM Replacement Motors & Pumps

The fastest way to get the exact OEM part number is to check the metal nameplate (data tag) riveted directly to the side of the motor or pump housing.

OEM stands for Original Equipment Manufacturer, meaning the part was made by (or to the exact specifications of) the company that originally built your compressor — ensuring proper fit and performance compared to generic aftermarket alternatives.

To find the right replacement motor or pump, match your compressor's model number and voltage/phase rating (found on the nameplate) to the corresponding part in our California Air Tools OEM lineup, such as the SP-9421 or SP-9413 series.

OEM parts like our California Air Tools replacement motors and pumps are built to the exact specifications of your original compressor, ensuring proper fit, performance, and often longer service life compared to generic aftermarket parts that may not match tolerances or electrical ratings exactly.

Yes — even a correctly matched OEM replacement can fail prematurely if it's installed incorrectly, run on the wrong voltage, or if an underlying issue elsewhere in the compressor (like a failing capacitor or pressure switch) caused the original part to fail in the first place; it's worth diagnosing the root cause before replacing.

If your motor or pump is a well-matched OEM replacement, like our California Air Tools lineup, and the rest of the compressor is in good shape, replacing just the failed component is usually more cost-effective than repairing it — but if the unit is old and multiple parts are failing, it may be time to consider a full replacement compressor instead.
