Frequently Asked Questions

Which fuel injector fits a Case 450 dozer?

For the Case 450 and 450B, Broken Tractor carries the Pencil Style Fuel Injector for Case 188 Engines (SKU A140829). The 450C uses a different Cummins-type injector (SKU J909476) with a 9 MM tip. Match the injector to your engine platform, and our parts team can confirm the correct fit if you are unsure.

What does a fuel injector do on a Case dozer?

A fuel injector delivers atomized diesel fuel into the combustion chamber for ignition. Broken Tractor carries pencil-style and Cummins-type injectors for Case dozers across the Case 188, Cummins 4B/6B, and Iveco 445 engine platforms. Choosing the right one depends on your engine and nozzle configuration.

What causes fuel injector damage on a Case dozer?

Common causes include contaminated or water in fuel, worn nozzle tips, and carbon buildup that disrupts the spray pattern. A failing injector often shows up as rough running, hard starting, smoke, or loss of power. Broken Tractor carries replacement pencil-style and Cummins-type injectors in 7 MM, 9 MM tip, and 14 MM top thread variants.

How do I tell a pencil-style injector from a Cummins-type injector on my Case dozer?

Pencil-style injectors are used on the Case 188 and other Case diesel engines, while Cummins-type direct-fit injectors are used on Cummins 4B/6B platforms found in later machines like the 850E, 855E, 1150E, and 1150G. Nozzle sizes also vary between 7 MM, 9 MM tip, and 14 MM top thread. Match the part number to your engine, or call our parts team at (800) 909-7060 to confirm.

Which injector fits a Case 850 or 1150 dozer?

It depends on the exact model and engine. The Pencil Style Fuel Injector for Case Diesel Engines (SKU A138322) fits the 850, 850B, 850C, 1150, 1150B, 1150C, and 1150D, while later Cummins-powered machines like the 850D, 855D, 1150E, and 1150G use the Cummins-type injectors (SKU J909476 or SKU 3280048). Confirm your model and engine to match the correct injector.
