Frequently Asked Questions
Which crankshaft fits a Case 580C or 580D backhoe?
Case 580C and 580D backhoes with the 207 cubic inch non-turbo diesel engine use crankshaft A144011. Some earlier Case backhoes ran the 188 engine instead, so confirm which engine your machine has before ordering. Matching the part number stamped on your old crankshaft or engine paperwork is the surest way to get the right fit.
What crankshaft fits a Case 580K, 580L or 580M with the Cummins 4-390 engine?
Crankshaft 3907803 fits Cummins 4-390 and 4T-390 engines in the Case 580K, 580SK, 580L, 580SL, 580M, 580SM and 580SE backhoes. The same crankshaft also fits the 590T, 590SL, 590SM, 570LXT and 570MXT. Broken Tractor offers it with fast shipping from Baton Rouge, LA and Kimbolton, OH.
Which crankshaft fits a Case 580 or 580B with the 188 engine?
Crankshaft A151015 fits Case 188 gas and diesel engines in the 530, 580, 580B, 480B, 480C, 480D and 310 backhoes. Because some of these models were built with different engines, check that your backhoe has the 188 engine before ordering. If you are unsure, call (800) 909-7060 and the parts team can help confirm fitment.
What crankshaft fits a Case 310 or 320 backhoe with the G148 gas engine?
Crankshaft G11700 fits the G148 gas engine used in the Case 300, 300B, 310, 320 and 400B backhoes. The Case 310 also appears in the fitment for the 188 engine crankshaft A151015, so the correct part depends on which engine your 310 has. Compare the part number on your old crankshaft or confirm your engine before buying.
Do I need a gasket set when replacing a Case backhoe crankshaft?
Broken Tractor offers lower gasket set A40713 with seals as a separate part to help complete a crankshaft replacement on 188-engine Case backhoes. It fits backhoes including the 580, 580B, 580C, 580CK, 580D, 480B, 480D, 530C and 310. Fitment can vary by model, so match the part number to your machine before ordering.
