# Horizon Fitness CST3 TM119-1US Treadmill DC Drive Motor JM05-015 (MP273)

## Product Introduction

The Horizon Fitness CST3 TM119-1US Treadmill DC Drive Motor JM05-015 (MP273) is a replacement treadmill drive motor for the Horizon Fitness CST3 treadmill. The drive motor powers the treadmill belt system during operation, so a worn or failed motor can prevent the machine from running properly. This part may help restore the function of a compatible treadmill without replacing the entire unit.

This item is listed as a used fitness equipment part. Skilled technicians carefully inspect each part for performance and safety before shipment. It provides a practical replacement option for repair technicians, fitness equipment owners, and anyone maintaining a Horizon Fitness treadmill with a matching motor specification.

## Product Details and Benefits

This product is a DC drive motor designed for use in a treadmill drive system. It replaces the original treadmill motor when the existing component has failed, become worn, or requires replacement. A functioning drive motor helps the treadmill move the walking belt at the selected speed.

The motor carries the following identifying information:

\- \*\*Brand:\*\* Horizon Fitness  
\- \*\*Equipment type:\*\* Treadmill  
\- \*\*Compatible treadmill model:\*\* CST3 TM119-1US  
\- \*\*Motor part number:\*\* JM05-015  
\- \*\*Product SKU:\*\* MP273  
\- \*\*Barcode/SKU reference:\*\* MP273  
\- \*\*Listed serial number:\*\* TM119-B04080021  
\- \*\*Condition:\*\* Used fitness equipment part  
\- \*\*Product category:\*\* Treadmill drive motors

Replacing only the faulty drive motor can support a more focused repair and may help extend the useful life of the treadmill. Reusing an inspected fitness component can also reduce unnecessary waste compared with discarding the complete machine.

## Compatibility and Applications

The Horizon Fitness JM05-015 DC drive motor is identified for the \*\*Horizon Fitness CST3 TM119-1US treadmill\*\*. It is intended to replace the drive motor used in that specific treadmill application. Use this motor for treadmill repair or parts replacement when the original motor matches the JM05-015 part number and the CST3 TM119-1US model information.

Compatibility depends on the exact treadmill model and motor specification. Do not assume that this motor fits every Horizon Fitness treadmill or every CST3 variant. Compare the model number, original motor part number, serial information, and physical connection details with your existing part before ordering.

## Why Choose This Product

This replacement motor gives you a way to repair a compatible Horizon Fitness treadmill using the required drive component rather than replacing the entire treadmill. The part has been inspected by trained technicians, which helps you make a more informed purchase when sourcing a used treadmill motor. It may suit home treadmill owners, repair businesses, gyms, and service professionals who need a JM05-015 replacement.

## Before You Buy

Confirm that your treadmill is a \*\*Horizon Fitness CST3 TM119-1US\*\* and that the original drive motor uses part number \*\*JM05-015\*\*. Check the listed serial reference, \*\*TM119-B04080021\*\*, against your equipment records when applicable. Product images serve as a reference only because stock may include multiple units, and the appearance of the part may vary slightly.
