Frequently Asked Questions

Are the left and right differential side gears the same on a Case 580C?

No, Broken Tractor lists them as two separate parts: a left-hand rear differential side gear (A50990) and a right-hand differential side gear (A50989). Both fit the Case 480C, 480D, 580C and 580D backhoes, so order the side you are replacing. We also carry the matching spider gear (A142676), spider gear pin (A146541) and differential shaft (A144266) for these models.

Should I rebuild or replace the transaxle on a Case 580D?

Both options are available. Broken Tractor offers a rebuilt transaxle (CS-580C-TRAXL-R) for the Case 580C and 580D, plus a transaxle rebuild kit (A150159R-Kit) for the 480C, 480D, 580C and 580D. The rebuild kit is marked with an asterisk for the 480D, so confirm fitment by serial number with our parts team before ordering.

What rear axle bearing and seal kit fits a Case 580C backhoe?

The Rear Axle Bearing and Seal Kit (CS-580-RA-Kit) fits the Case 480C, 480D, 480E, 480F, 580C, 580D, 580 Super E and 580K, with the 580K marked for fitment confirmation. For the brake side we also carry the Brake Backing Plate Bearing and Seal Kit (CS-580-BPK), and we offer individual seals such as the right-hand differential side gear seal (A49795) and the rear axle oil seal (A61448).

Is there a ring gear and pinion set for the Case 480C and 580C?

Yes, the Rear Axle Ring Gear and Pinion Set (A51980) fits the Case 480C, 480D, 580C and 580D. Broken Tractor also carries a ring gear hub (A156117) that fits only the 480C and 580C 2WD non-turbo machines. Fitment can depend on model and configuration, so match your old part number or call (800) 909-7060 to confirm before ordering.

What rear wheel spacer kits fit a Case 580D?

Broken Tractor offers two 8-bolt rear rim chain spacer kits that fit the Case 580D: one in high-strength aluminum (CS-WSPKIT-2) and one in steel (CS-WSPKIT-2-Steel). Both also fit the 480B, 480C, 480D, 480E, 480F, 580B, 580C, 580E and 580 Super E. Fitment on the 580K is marked for confirmation, so check with our parts team for that model.
