Frequently Asked Questions

How do I tell if my Case 580K has a 3-bolt or 4-bolt steering cylinder?

It depends on your serial number. Parts for the 4-bolt steering cylinder gland are listed for the 580K after serial number JJG0020000, while the 3-bolt steering cylinder kit (N14622) and the 3-bolt tie rod ball joints (N14402 left hand, N14379 right hand) are listed for the 580K. Check your serial number and count the mounting bolts on the cylinder before ordering, or call (800) 909-7060 and our parts team can help confirm.

What steering cylinder fits a Case 590 Super M 4WD backhoe?

The 4WD Power Steering Cylinder (D149729) fits the Case 590 Super M before serial number N4C999999. The same cylinder also fits the 580K after serial number JJG0020000, 580 Super K, 590 Turbo and 590 Super L. If your 590 Super M is past that serial number break, match your existing part number before ordering.

Can I reseal a leaking Case 580 Super L steering cylinder instead of replacing it?

Yes, Broken Tractor offers a 4WD Steering Cylinder Seal Kit (D149739) for resealing the cylinder. It fits the Case 580L, 580 Super L, 580M, 580 Super M, 580 Super K, 590 Turbo, 590 Super L, 590 Super M, and the 580K after serial number JJG0020000 with the 4-bolt steering cylinder. The seal kit covers a wider model range than the hard parts, so check the individual fitment for your machine.

Which front axle U-joint fits a Case 580K backhoe?

It depends on the serial number and the position of the joint. The Front Axle Driveshaft U-Joint (D144306) fits the 580K after serial number JJG0020000, the 580 Super K and the 590 Turbo, while the Transmission to Steering Axle U-Joint (R2713) fits the 580K before serial number JJG0020000. We also carry the Front Axle Drive Shaft U-Joint (9968059), which fits a broad range including the 580K, 580L, 580M and 590 series, so verify the exact position you need before ordering.

What parts make up the Case 580K 4WD front axle drive shaft?

The drive shaft components are sold separately, including the front axle inner shaft (9968057), outer short hub drive shaft (N14409), drive shaft connecting body (N14412), U-joints, and drive shaft snap ring (N14410). These parts fit 4WD front axles only, not 2WD machines. Verify the exact position you are replacing so you order the correct piece.
