One New Aftermarket Replacement Swing Tower to Boom Cylinder Pin Fits Case (Fits Case IH) 580K and 580SK Backhoe Loaders
This aftermarket replacement pin connects the swing tower to the boom cylinder tube on Fits Case 580K and 580SK backhoe loaders. The pin features a bolt hole through the center retained by a 9/16″ bolt, and grease fittings located at both ends for serviceability. Heat treated for durability in demanding excavation applications. Note: Most 580K backhoes use this bolt-hole style pin. Later models may use a snap ring-style pin (part number D144420) — verify your machine’s pin style before ordering.
