# StarTrac 9-3573-MUSAP3 Treadmill DC Drive Motor L5D011 (MP240)

## Product Introduction

The StarTrac 9-3573-MUSAP3 Treadmill DC Drive Motor L5D011 is a replacement treadmill drive motor for compatible Star Trac fitness equipment. This DC motor forms part of the treadmill’s belt-drive system and helps provide the mechanical power needed for belt movement during operation. If the original motor has failed or requires replacement, this component may help restore the treadmill’s drive system without replacing the entire machine.

This product is listed under the local product name \*\*MP240\*\*. It is sold as a Star Trac treadmill DC drive motor and carries the part reference \*\*L5D011\*\*.

## Product Details and Benefits

The \*\*StarTrac 9-3573-MUSAP3 treadmill motor\*\* is identified by several reference numbers, making it easier to compare against the motor currently installed in your equipment:

\- \*\*Brand:\*\* Star Trac  
\- \*\*Product type:\*\* Treadmill DC drive motor  
\- \*\*Part number:\*\* L5D011

A treadmill drive motor transfers power to the belt-drive system. When the motor operates correctly, it supports the treadmill’s normal belt movement. Replacing a failed or worn motor can help address drive-system problems and support the continued use of compatible Star Trac equipment.

This component suits repair projects, treadmill maintenance, and replacement-part sourcing. It may be useful for fitness equipment technicians, service departments, gyms, commercial facilities, and owners repairing a Star Trac treadmill. Because the product listing does not provide electrical ratings, dimensions, mounting details, connector information, or motor output, buyers should confirm those details before ordering.

## Compatibility and Applications

This replacement motor is associated with the \*\*StarTrac 9-3573-MUSAP3 treadmill\*\*. The listing identifies it as a \*\*Star Trac treadmill DC drive motor\*\*, with the reference \*\*L5D011\*\*. Use these identifiers to compare the replacement with the motor and equipment records for your treadmill.

The product page also lists the serial number reference \*\*TRSX1601-L01084\*\*. Treat this information as an equipment identification reference and confirm that it matches your treadmill or service documentation before purchase.

The motor is intended for use as a replacement component in the treadmill drive system. It is not described as a complete treadmill, control board, belt, roller, or installation kit. The available product information does not confirm compatibility with other Star Trac models, other brands, or equipment with different part numbers.

## Why Choose This Product

Choosing a replacement motor with the correct Star Trac, model, and part references can make equipment repair more straightforward. The exact identifiers help you compare the part with the original component instead of relying only on the treadmill’s general brand or appearance. A suitable replacement can also help you maintain existing equipment when replacing the complete treadmill is unnecessary.

## Before You Buy

\- StarTrac 9-3573-MUSAP3  
\- L5D011  
\- MP240  
\- Serial reference TRSX1601-L01084

Also verify the motor’s physical fit, mounting arrangement, electrical specifications, connectors, and other installation requirements with a qualified technician or the treadmill’s documentation. The product page does not state dimensions, voltage, horsepower, condition, warranty, or package contents, so confirm these details before placing your order.
