Frequently Asked Questions

Which loader lift cylinder seal kit fits a Case 580 Super N wide track?

The 580 Super N Wide Track uses lift cylinder seal kit 84258339, which also fits the 590 Super N. Standard track 580N and 580 Super N loaders use a different lift cylinder seal kit, 84257323. Confirm whether your machine is a wide track model before ordering, since the two kits are not interchangeable.

What seal kits does a Case 580 Super N backhoe need for the boom, dipper and bucket cylinders?

Broken Tractor carries a separate seal kit for each backhoe cylinder on the 580 Super N. These are boom cylinder kit 84259219, dipper cylinder kit 84259222, and backhoe bucket cylinder kit 84259225, which also fits the 590 Super N. Match the kit to the cylinder position you are resealing.

Is the stabilizer cylinder seal kit the same on a Case 580 Super N and 580 Super N WT?

No, the standard and wide track machines use different stabilizer cylinder seal kits. Kit 84259227 fits the 580 Super N stabilizer on non wide track machines and the 580N boom cylinder on Tier 3 non wide track models. Kit 84259228 fits the 580 Super N WT and the 590 Super N.

Which swing cylinder seal kit fits a Case 580 Super N?

Swing cylinder seal kit 122535A1 fits the 580 Super N, 580 Super N WT and 590 Super N, along with the 580L, 580M and Super L and Super M models. It is listed for Bulldog or Hercules hydraulic cylinders, so check which cylinder brand is on your machine before ordering. If you are unsure, match the part number on your old kit or call (800) 909-7060 to confirm with the parts team.

What tools do I need to reseal a hydraulic cylinder on a Case 580 Super N backhoe?

We carry a Case hydraulic spanner wrench, CAS-1456A, for cylinder repair on Case backhoes. We also offer a hydraulic gland seal installation tool kit, CAS-1457, for fitting new seals on backhoe cylinders. Rubber hydraulic line support blocks L79937 and D38648 fit the 580 Super N and 590 Super N if the old supports need replacing during the job.
