Frequently Asked Questions
What camshaft parts fit a Cummins 4B engine in a Case excavator?
We carry camshaft bushings, front camshaft bushings, and used camshaft and gear assemblies for the Cummins 4B, 4BT, and 4BTA390 engines. Confirm the exact engine designation before ordering, since components vary by build. Match the part number to be sure of the correct fit.
Are the camshafts new or used?
Both. The camshaft bushings are new replacement parts, while the camshaft and gear assemblies are quality used components pulled from Cummins 4B and 4BT engines. Each listing specifies its condition.
Does the used camshaft come with the gear?
Yes. The used Cummins 4B and 4BT camshaft is supplied with its gear as an assembly. To verify it matches your engine, confirm the part number or reach the parts team at (800) 909-7060.
How do I know which camshaft bushing I need?
Identify whether you need the front camshaft bushing or a standard camshaft bushing, then match by engine series. Both fit the Cummins 4B and 6B family, but position and part number determine the correct component.
