Frequently Asked Questions

What is included in a Case backhoe hydraulic cylinder seal kit?

Our Case backhoe hydraulic cylinder seal kits include rod seals, piston seals, wipers, O-rings, and backup rings. These are the components needed to rebuild a cylinder rather than replace the whole assembly. Kits are sorted by cylinder function so you can choose the one for the boom, dipper, bucket, swing, stabilizer, or loader lift cylinder.

How do I find the right hydraulic cylinder seal kit for my Case backhoe?

Match the kit to the cylinder bore and rod diameter, since the same machine can use different cylinders for the boom, dipper, bucket, swing, stabilizer, and loader functions. It also helps to confirm your exact model and serial number, as fitment can vary across generations. If you are unsure which kit fits, our parts team can help you match the correct one at (800) 909-7060.

Do you carry seal kits for the Case 580C backhoe?

Yes, Broken Tractor carries hydraulic cylinder seal kits covering the 580 series including the 580C, along with the 480, 580L, and 590 series machines. Because each machine has several cylinders, identify which cylinder you are rebuilding and match the kit to its bore and rod diameter. Confirm your model and serial number so the correct kit is selected.

Can I rebuild a Case backhoe cylinder instead of replacing it?

Yes, a seal kit lets you rebuild a leaking or worn cylinder by replacing the rod seals, piston seals, wipers, O-rings, and backup rings. This is often a lower cost option than replacing the entire cylinder when the barrel and rod are still in good condition. Match the kit to the cylinder bore and rod diameter for a proper fit.

What Case backhoe models do your hydraulic seal kits fit?

Our seal kits cover a wide range of Case backhoe loaders, including the 480C, 480D, 480E, 480F, and 480LL; the 580B, 580C, 580D, 580E, 580K, and 580 Super K; the 580L, 580M, 580 Super L, and 580 Super M; and the 590 Super L, 590 Super M, and 590 Super N. Since kits are specific to each cylinder, match by bore and rod diameter and confirm your serial number for correct fitment.
