Frequently Asked Questions

What rear axle hub and planetary parts fit a Case 580N backhoe?

Broken Tractor carries a full set of rear wheel end parts for the Case 580N and 580 Super N. These include the rear axle spindle hub (87708445), planetary carrier (87708452), planetary ring gear (87708467), planetary gear and bearing kit (47874511), rear axle hub bearing (K395101), spindle nut (87708454), O-ring (87711038), and rear axle differential flange (48053638). We also offer a complete rear axle planetary assembly (47566688) for the 580N and 580 Super N.

Which rear axle planetary gear and bearing kit fits a Case 590 Super N?

For the Case 590 Super N, 590 Super N WT, 590 Super M Series 3 and 580 Super M+ Series 3, the matching planetary gear and bearing part is 87708967. The 580N and 580 Super N use a different kit, 47874511, so the two are not interchangeable across models. Because fitment depends on the exact model, match your existing part number or confirm with the parts team before ordering.

Can I replace the whole rear axle planetary on a Case 580M Series 3 instead of rebuilding it?

Yes. Broken Tractor offers a complete new rear axle planetary assembly (47566688) and a used drive axle planetary assembly (87395372-Corner). Both fit the Case 580M Series III, 580 Super M Series III, 580N and 580 Super N. If you would rather rebuild, we also carry the individual carrier, ring gear, gear and bearing kit, hub bearing, spindle nut and O-ring.

Do the rear wheel lug studs and lug nuts fit older Case 580L and 580 Super L backhoes?

Yes. The rear axle lug stud (D142986) and rear wheel lug nut (D138492) fit the Case 580L, 580 Super L, 580M, 580 Super M, 580N and 580 Super N. They also fit the 590 Super L, 590 Super M and 590 Super N, so one part number covers several generations of Case backhoes.

Which Case backhoes use the outer rear axle bearing 371148A1?

The outer rear axle bearing 371148A1 is listed for the Case 580 Super M+ Series 3 and 590 Super M Series 3. It is not listed for the 580N or 580 Super N, which use the rear axle hub bearing K395101 instead. If you are unsure which bearing your machine takes, call (800) 909-7060 with your model and serial number before ordering.
