Frequently Asked Questions

How do I know which crankshaft fits my Case dozer engine?

Fitment depends on your engine family and displacement, so start by identifying whether your machine runs a Cummins 4.390, 4T390, 6.590, 6T590 or a Case 188, 207, 251, 267, 301, or 336 engine. Many Case dozers also have a serial break that changes the correct part, so verify displacement and serial number before ordering. Match the part number to your engine or confirm the correct crankshaft with our parts team at (800) 909-7060.

What crankshaft fits a Case 850D or 850G dozer?

We carry crankshafts for the Cummins 6.590 engine used in the 850D, 850E, and 850G, including SKU 3907804 and SKU J918324, which also cover 855D, 855E, 1150E, 1150G, and 1150H applications. Because these dozers span multiple engine generations, confirm your engine displacement and serial break so you order the matching unit.

Which crankshaft fits the Case 750 and 850 dozer with a 301 engine?

Broken Tractor offers crankshaft SKU A22578 for the Case 301D engine in the 750 and 850 dozer. We also carry SKU A166001 for Case 251, 267, 301, and 336BD engines that covers the 750, 850, and 850B. Verify your engine series before ordering since these models used more than one engine over their production run.

Do you have new and used Case dozer crankshafts?

Yes, Broken Tractor stocks both new and used crankshaft assemblies across the Case dozer engine families, including Cummins 4.390, 4T390, 6.590, 6T590 and Case 188, 207, 251, 267, 301, and 336 engines. Availability varies by engine, so match the part number to your application to get the correct unit.

What does a dozer engine crankshaft do and when should it be replaced?

The crankshaft converts the up and down motion of the pistons into rotational output that drives the dozer drivetrain. It is typically replaced during an engine rebuild or after damage from bearing failure, scoring, or a spun bearing. Confirm your engine displacement and serial break when selecting a replacement so the crankshaft matches your engine.
