Frequently Asked Questions

What does the swing tower do on a Case backhoe?

The swing tower pivots the backhoe boom left and right during digging and trenching. It is a core part of the rear backhoe assembly and takes constant load, so its pivot points wear over time. Broken Tractor carries used OEM towers and pin and bushing rebuild kits for Case backhoes.

Which swing tower fits a 580 Super L or 580 Super M?

We carry a used OEM swing tower for the 580 Super L and 580 Super M under SKU 326805A1-U. If you prefer to rebuild your existing tower instead of replacing it, we also offer the Swing Tower Repair Kit under SKU 249867A1Kit for those same models. Always verify the part number against your serial range before ordering.

Should I replace the swing tower or install a pin and bushing kit?

If the tower casting is sound and only the pivot points are worn, a pin and bushing rebuild kit restores the joints without a full replacement. If the tower itself is cracked or badly worn, a used OEM swing tower is the better fix. Broken Tractor offers both options for the 580L, 580M, 580N, and 580 Super N series among others.

Do you have a swing tower for the 580N and 580 Super N?

Yes, we carry a used swing tower for the 580N and 580 Super N under SKU 84304025, and a matching pin and bushing rebuild kit under SKU 84304025-PBK. Verify the part number against your serial range before ordering, since fitment can vary within a model generation.

How do I know which swing tower matches my Case backhoe?

Match the part number on your existing tower to the SKU that covers your model, since fitment depends on model generation and serial range. We offer towers spanning the 580K, 580L, 580M, 580N, and 590 series. If you are unsure which one fits your machine, confirm with our parts team at (800) 909-7060.
