Product description

The Chuck Arm Pin (Part 4004878) is a precision-machined pivot component that facilitates the smooth movement of the chucking arms on Snap-On tire changers. These pins are subjected to extreme shear forces and constant friction during the wheel clamping process, making them critical for the overall stability and safety of the machine. A worn or sheared pin can lead to uneven clamping pressure, arm wobbling, or total failure to secure the wheel, which can be dangerous during operation. This hardened steel pin is manufactured to exacting tolerances to ensure a tight, slop-free fit, restoring the original mechanical geometry and clamping reliability of your tire service equipment for long-term durability in the shop.
