## Star Trac 9-9051-MUNBO Treadmill Rear Idler Roller (RP665)
The Star Trac 9-9051-MUNBO Treadmill Rear Idler Roller is a preowned replacement roller for the rear section of a compatible Star Trac treadmill. It helps support the running belt and allows the belt to move through the rear of the machine during use. If the existing rear idler roller shows wear, damage, or requires replacement, this part can help restore the treadmill’s original roller assembly without replacing the entire machine.
Product Details and Benefits
This Star Trac treadmill rear idler roller carries the part number **RP665** and SKU **RP665**. It belongs to the **Treadmill Rollers** category and comes in preowned condition. Each part has been carefully inspected by skilled technicians before sale to help confirm its condition and support safe, reliable use.
As a used fitness equipment component, this roller gives repair technicians, service departments, gym operators, and treadmill owners an option for replacing a specific component instead of discarding a complete treadmill. Reusing a serviceable part can also help extend the operating life of existing fitness equipment and reduce unnecessary waste.
The rear idler roller forms part of the treadmill’s belt support and tracking system. A properly matched replacement can help address a worn or damaged rear roller when the rest of the treadmill remains suitable for continued service. Because this is a replacement component rather than a complete treadmill assembly, buyers should confirm that the roller matches the original part before ordering.
