Frequently Asked Questions

Which ring and pinion set fits a Case 580 Super E?

It depends on the serial number of your 580 Super E. Before serial number 16270319, the 580 Super E uses the A168102 ring and pinion set for 2WD machines or the A168108 set for 4WD drive axles. After serial number 16270319, the 580 Super E uses the A168883 ring gear and pinion set, which also fits the 580K before serial number JJG0020000.

What is the serial number break for Case 580K rear axle parts?

The early 580K rear axle parts Broken Tractor carries fit 580K backhoes built before serial number JJG0020000. That break applies to the left-hand and right-hand differential side gears (1342925C1 and 1342927C1), the A168883 ring and pinion set, the A179986 ring gear hub and the CS-580K1-TRAXL-R rebuilt transaxle. Several other parts, such as the axle shaft, bull gear and cross shaft, list the 580K with a serial limitation, so confirm your serial number before ordering. If you are unsure, call (800) 909-7060 and the parts team can help match the part to your machine.

Is there a rebuilt transaxle for a Case 580E or 580 Super E?

Yes, Broken Tractor offers a rebuilt backhoe transaxle (SKU CS-580E-TRAXL-R) that fits the Case 580E and 580 Super E. For the early 580K before serial number JJG0020000, there is a separate rebuilt transaxle (SKU CS-580K1-TRAXL-R). If only a few internal parts are worn, we also carry individual differential gears, ring and pinion sets, bull gears and axle shafts for these machines.

What rear axle and differential parts fit a Case 580 Super E?

We carry a full range of rear axle parts for the Case 580 Super E, including the A154936 rear axle shaft, A154940 bull gear, A156376 differential cross shaft and A179986 ring gear hub. Differential internals include the A179762 spider pinion gear, A153711 spider gear pin, K261065 pinion lock washer and the CS-580-RA-Kit rear axle bearing and seal kit. The side gears and ring and pinion sets have serial number breaks, so match the part number or confirm your serial number before ordering.

What is the difference between the aluminum and steel rear rim spacer kits for a Case 580E?

Both are 8-bolt rear rim chain spacer kits that fit the Case 580E, 580 Super E and 580K, along with earlier 580B, 580C and 580D backhoes. The CS-WSPKIT-2 kit is made from high-strength aluminum, and the CS-WSPKIT-2-Steel kit is made from steel. The 580K is listed with a serial limitation, so confirm fitment for your machine before ordering.
