The Life Fitness FTR Treadmill Motor Drive Belt 8878101, SKU MX757, is a preowned replacement belt for the motor drive system in a Life Fitness FTR treadmill.

Product Details and Benefits
This product is identified as the Life Fitness FTR treadmill motor drive belt. Its manufacturer part number is **8878101**, and its local SKU and barcode are **MX757**. The belt comes from a preowned fitness equipment part inventory and offers a practical option for treadmill repair or maintenance.
A motor drive belt plays an important role in treadmill operation. It connects the motor’s output to the treadmill’s drive system and transfers the motor’s rotation to the running belt assembly. When the belt becomes damaged or loses its ability to maintain proper tension, the treadmill may experience drive problems, unusual operation, or failure to move correctly. Replacing the affected belt can help address the original belt-related issue and support the continued use of the treadmill.
Each part has been carefully inspected by skilled technicians for performance and safety before sale. Because this is a used fitness equipment component, the belt may show signs of previous use. The product listing uses reference images, and the appearance may vary slightly because multiple units may be available. The seller states that the supplied part will remain the exact model and part type listed.
