Product description

The Coats 8109944 Special Washer is a precision-engineered component with a 1.5-inch inner diameter, specifically designed for use on wheel balancer shafts and mounting assemblies. This washer provides a stable bearing surface and proper spacing for hub nuts and wheel adapters, ensuring that the wheel is centered and securely clamped during the balancing process. Due to the high rotational speeds and repeated clamping cycles, these washers can become warped, pitted, or worn over time, which directly affects the accuracy of the balance. A compromised washer can lead to vibration issues or uneven tire wear for the end customer. Replacing this special washer is a simple yet effective way to maintain the calibration and performance of your Coats balancing equipment.
