Frequently Asked Questions
What engines fit a Case W11 or W11B wheel loader?
Broken Tractor carries the Cummins 4B/4BT complete engine (SKU CS-4390-LB-N) that fits the W11B, and the Case 207 rebuilt complete diesel engine (SKU CS-207-ENG) that fits the W11. Since fitment can vary by generation, match the part number to your machine or confirm with our parts team before ordering.
Which Cummins engine goes in a Case 621, 721, or 821 wheel loader?
For the 621, 621B, and 621C we carry the Cummins 6-cylinder 5.9L long block (SKU CS-6590-LB-N), and for the 721, 721B, 721C, 821, 821B, and 821C we offer the Cummins 6T830 turbo diesel (SKU CS-6T830-LB-N). Both are offered less fuel system, so plan to transfer your existing fuel components. Confirm the correct assembly for your serial number if you are unsure.
What does a Case wheel loader long block engine include?
A long block covers the core engine assembly and is offered complete or less fuel system depending on the SKU. For example, the CS-6590-LB-N and CS-6T830-LB-N are supplied less fuel system, so you reuse or supply your own fuel system parts. Check the individual listing to see exactly what is covered before you buy.
Is the Case 207 engine a complete rebuilt engine for the W14 loader?
The Case 207 rebuilt complete diesel engine (SKU CS-207-ENG) is a complete rebuilt assembly, but its listed fitment covers the W11 rather than the W14 series. For W14B and W14C machines, look at the Cummins 6-cylinder 5.9L long block (SKU CS-6590-LB-N). Verify the part number against your loader before ordering.
How do I know which complete engine is correct for my Case wheel loader?
Match your loader model and serial number to the fitment listed on each engine, since Case used different Cummins power plants across W-series generations. We verify fitment before every engine ships, and you can confirm the right assembly by calling our parts team at (800) 909-7060.
