## Product Details and Benefits

This product is a DC drive motor for a Life Fitness treadmill. The motor forms part of the treadmill’s drive system, which transfers power to the belt and supports normal belt movement. Replacing the motor can address a drive-system fault when the existing motor no longer performs correctly.

The listed part number is \*\*S3456B3714\*\*, and the product SKU is \*\*MP326\*\*. These identifiers help you compare the motor with the component currently installed in your treadmill. Matching the part number before ordering can reduce the risk of purchasing an incompatible replacement.

A treadmill drive motor replacement can support equipment repair in fitness centers, gyms, service departments, and home exercise spaces that use compatible Life Fitness treadmills. It may also provide a practical option for treadmill technicians or equipment owners who need to replace the motor rather than replace the complete machine.

This listing identifies the product specifically as a \*\*Life Fitness treadmill DC drive motor\*\*.
