\## Star Trac 9-7631-MUSAP0 Treadmill Polar Receiver Cable 715-351

The Star Trac 9-7631-MUSAP0 Treadmill Polar RCVR Cable 715-351 is a replacement receiver cable for a Star Trac treadmill system. It connects to the treadmill’s Polar receiver setup and is intended for equipment that requires this specific cable part. If you are repairing a Star Trac treadmill and need the original 715-351 cable, this part provides a direct way to identify the component you need before ordering.

This product is listed under the part number \*\*9-7631-MUSAP0\*\* and cable number \*\*715-351\*\*. The product listing also identifies it as \*\*MX321\*\*, which serves as the local product name, SKU, and barcode. Use these reference numbers when comparing the cable with the part removed from your treadmill or when checking service and replacement records.

## Product Details and Benefits

The Star Trac Polar receiver cable is a dedicated treadmill cable rather than a general-purpose cable. Its function relates to the Polar receiver connection in compatible Star Trac equipment. Replacing the correct cable can help address a missing, damaged, or otherwise unusable receiver cable during treadmill repair or maintenance.

Because this is a model- and part-number-specific component, the identifying information is important. The product name includes the Star Trac equipment brand, the treadmill reference \*\*9-7631-MUSAP0\*\*, the Polar receiver description, and the cable number \*\*715-351\*\*. These details help technicians, equipment owners, and fitness service providers distinguish this item from other treadmill cables.

The product page does not provide dimensions, cable length, material, color, connector details, installation instructions, package quantity, condition, or warranty information. Confirm those requirements before purchase if your repair depends on a specific physical specification.

## Compatibility and Applications

This cable is associated with \*\*Star Trac treadmills\*\* and the \*\*Polar receiver\*\* connection identified in the product title. It is intended for use when the required replacement reference is \*\*9-7631-MUSAP0\*\* or \*\*715-351\*\*. The listing does not provide a complete list of compatible treadmill models, so buyers should not assume that every Star Trac treadmill uses this cable.

Typical applications include treadmill service, replacement of the existing Polar receiver cable, and maintenance of Star Trac fitness equipment. The cable may suit a repair where the original part has been lost or needs replacement, but compatibility should be confirmed using the treadmill’s model information and the part number printed on the existing cable or service documentation.

## Why Choose This Product

This Star Trac replacement cable gives buyers a clearly identified part for a specific treadmill receiver connection. Matching the brand and part number before ordering helps reduce the risk of selecting an unrelated cable. The MX321 reference also provides an additional way to locate the product in purchasing, inventory, or repair records.
