Frequently Asked Questions

What front axle parts fit a Case 580K 4WD backhoe?

Broken Tractor carries king pin kits, axle studs with and without collar, and drive shaft clamp brackets for the four wheel drive front axle on the Case 580K, 580 Super K and 590 Turbo backhoes. Parts cover both early and late production variants, so check your machine's model and serial number before ordering.

Does the Case 580K king pin kit fit a 590 Turbo?

Not always. The 580K and 580 Super K use their own dedicated king pin kit, while 590 Turbo king pin fitment is limited to units built before Carraro axle serial number 4253. Check the serial number on your front axle before ordering.

Do I need Case 580K axle studs with collar or without collar?

It depends on your axle, because Broken Tractor offers both a with collar and a without collar version of the front axle stud. Compare the studs on your axle or match the old part number before ordering. If you are unsure which one your backhoe uses, call (800) 909-7060 and the parts team can help confirm.

Do Case 580K 4WD front axle studs fit older backhoes like the 580E or 580SE?

Yes, axle stud fitment also covers earlier Case four wheel drive backhoes, including the 480E, 480F, 580E, 580G and 580SE. Fitment varies by stud version, so confirm the model listing and part number on the specific stud before you order.

Will a Case 580 Super K drive shaft clamp bracket fit other Case backhoes?

Yes, the drive shaft clamp brackets share fitment across several Case 480, 580 and 590 series backhoes. Check the fitment list on the bracket against your exact model, and match your old part number to be sure.
