Case 580 Super M Backhoe Parts
Case 580 Super M Case Backhoe Parts
The hydraulic system on the Case 580 Super M depends on properly functioning cylinders across several attachment points, including the stabilizer, swing, and boom assemblies.
HW Part Store offers more than 20 products covering this range, giving operators and maintenance crews the ability to address leaks and wear without sourcing parts from multiple suppliers.
Aftermarket seal kits are specified by bore and rod dimensions, ensuring the correct kit is matched to the right cylinder application for an exact fit.
For 580 Super M outrigger and stabilizer cylinders, part numbers 199720A1, 199721A1, 135340A1, 135341A1, 177256A1, and 177257A1 are available, along with center-mount outrigger cylinder seal kits and sideshift outrigger seal kits.
Keeping seals and cylinder components on hand for the stabilizer and boom circuits means hydraulic leaks can be addressed as soon as they appear, rather than waiting on sourcing delays that extend machine downtime.
Pins, Bushings, and Structural Backhoe Parts
Beyond the hydraulic cylinders, the model relies on a network of pins, bushings, and structural components at every pivot point across the boom, dipper arm, swing tower, frame, and stabilizer assemblies.
Stabilizer plates are available in cleated, rubber pad, and flip-over configurations, while stabilizer leg bushings such as D50146, 107124A1, and D151070.
Case 580 Super M boom-to-swing-tower pins, including part numbers 292385A1 and D151065, are available alongside bushing sets for the upper and lower swing tower pivot.
Boom-to-dipper pins and dipper cylinder rod-end pins are constructed from 4140 steel alloy heat-treated to 65 Rockwell hardness, providing consistent load-bearing performance in high-stress applications.
All pins and bushings are American-made and carry part numbers corresponding to detailed assembly drawings, simplifying identification during repair planning.
