Finding the Right Aftermarket Parts by Part Number

This category covers replacement cylinders, seal kits, bushings, snap ring hardware, pin hardware, and related hydraulic parts built for Case 580 Super N backhoe applications across all tiers and serial number ranges. 

The outrigger cylinder seal kit is compatible with cylinder numbers 84210938, 84210947, 84421605, and 84421606, and is dimensioned for a 2-1/4-inch rod with a 4-1/2-inch bore. These specifications are critical when sourcing an exact-fit replacement. 

The left-hand and right-hand outrigger cylinders, part numbers 84421605 and 84421606 respectively, are American-made and pressure-tested before shipment. 

The swing cylinder seal kit is designed to cover cylinder numbers 139808A2, 84428583, and 47922074, with a 2-inch rod and a 4-inch bore. 

Additional seal kits are available within this parts catalog for the backhoe dipper cylinder, backhoe boom cylinder, backhoe bucket cylinder, loader lift cylinder, and loader bucket tilt cylinder, providing coverage across multiple cylinder positions in a single parts catalog.

Exact-fit Backhoe Loader Repair Parts

Before ordering replacement hydraulic parts for a boom, dipper, or swing position, confirm the rod size, bore size, cylinder number, serial number range, pivot pin condition, and machine tier. This identification and verification is essential for ensuring a proper fit and avoiding installation complications. 

The Case 580 Super N swing cylinder, for example, uses cylinder number 139808A2 with a 2-inch rod and a 4-inch bore, and fits all serial numbers across standard configurations.

Keeping exact-fitting replacement backhoe parts on hand, particularly for high-wear components such as outrigger and swing cylinders or boom and dipper cylinder seals, reduces the risk of extended downtime when a leaking cylinder or worn seal stops a job on the backhoe loader. 

For crews running multiple machines across job sites, having the correct parts available before a failure occurs helps manage maintenance costs and minimize schedule delays.
