Frequently Asked Questions

What loader pins and bushings fit a Case 580K backhoe?

Broken Tractor carries a full set of front loader pins and bushings for the Case 580K and 580 Super K. These include the loader bucket pin to frame (D129256), upper loader bucket pin (D129257), tilt cylinder rod pin to loader frame (D129279), loader lift cylinder tube pin (D135669), loader lift cylinder rod bushing (D144895), loader frame bushing (D129240), rear loader frame bushing (D37392) and the loader frame pivot cross shaft (182650A1). We also carry the loader hydraulic lift cylinder (110303A1) for these models.

Is there a loader pin and bushing rebuild kit for the Case 580 Super K?

Yes, Broken Tractor offers the Case Front Loader Pin and Bushing Rebuild Kit (CS-580SK-LPK), which fits both the Case 580K and 580 Super K. A kit lets you order loader pins and bushings in one purchase instead of sourcing each piece separately. Individual pins and bushings are also available if you only need to replace a few worn locations.

Do Case 580K loader pins and bushings also fit the 580 Super K and 590 Turbo?

Most of the loader pins and bushings we carry fit both the Case 580K and 580 Super K, and several also fit the 590 Turbo, such as the bucket pin to frame (D129256) and lift cylinder rod bushing (D144895). Some parts, like the loader bucket bushing (D129264), fit a wider range including the 580L, 580M, 580N and 590 Super series. Because fitment can vary by model and serial number, match the part number on your old part or confirm with our parts team by calling (800) 909-7060.
