Frequently Asked Questions

What planetary gear fits a Case 580K 4WD front axle?

Because fitment on the 580K depends on serial number, check your machine's serial number before ordering. If your 580K is below that serial number or you are unsure, match your old part number or call (800) 909-7060 so the parts team can confirm the right gear.
