BUSHING

In stock · ships from Knoxville

The Eaton 12815 bushing is a precision wear component found in Eaton Fuller manual transmissions, commonly used as a clutch shaft pilot bushing or release fork bushing ([finditparts.com](https://www.finditparts.com/products/3432657/eaton-12815), [fleetsworld.com](https://www.fleetsworld.com/products/12815-ns)). It provides a smooth, low-friction pivot that allows the clutch to engage and disengage cleanly. Over time, the bushing can oval out or seize, leading to hard shifting or clutch drag, so it is typically replaced during a clutch job or when transmission play is felt. The part fits many Class 7/8 trucks including Freightliner, International, and Mack models equipped with Eaton Fuller gearboxes, and the WEL suffix on your part number likely indicates a specific dealer or packaging variant.
