This pin typically connects the upper sections of the swing arm or tower assembly, allowing for the precise articulation needed to position the tool head over the wheel rim. Built to withstand significant vertical and lateral stresses, this pin is manufactured from hardened alloy steel to ensure it does not deform under the leverage applied during the tire mounting process. Its smooth, finished surface allows for easy lubrication and consistent movement, which is essential for operator ease of use and machine accuracy. Replacing a worn or bent upper pin is crucial for maintaining the precise vertical alignment of the mounting head.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHardened alloy steel for superior pivot strength\u003c\/li\u003e\n\u003cli\u003ePrecision-finished for smooth articulation of upper arms\u003c\/li\u003e\n\u003cli\u003eCritical for maintaining tool head vertical alignment\u003c\/li\u003e\n\u003cli\u003eDirect-fit replacement for Snap-On tower assemblies\u003c\/li\u003e\n\u003cli\u003eResistant to high leverage forces and mechanical wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Upper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Pivot Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Snap-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e st0004978\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eSnap-On Tire Changer Swing Arm and Tower Assemblies\u003c\/p\u003e\u003cp\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
