Frequently Asked Questions

What does the engine oil pressure sensor switch do on a Case dozer?

The oil pressure sensor switch monitors engine oil pressure and signals the gauge or warning light. A faulty sensor can cause a false low pressure reading or no reading at all. We carry replacement oil pressure sensor switches for Case machines.

How do I know if my Case dozer temperature sender is bad?

A failing engine temperature sender often shows an erratic gauge, a stuck reading, or a temperature light that stays on or off incorrectly. Replacing the sender is a common fix before assuming a larger cooling issue. We stock temperature sender units for Case dozers.

Do these ignition switches come with keys?

Yes, several of the ignition switches we carry ship with keys, and key sets are also available separately. Fitment depends on your model and serial range, so match the part number or confirm with our parts team.

Will one ignition switch fit multiple Case dozer models?

Many Case ignition switches share a common design across several dozer generations, but exact fitment varies. Verify by comparing the part number or call our parts team at (800) 909-7060 to confirm the right switch for your machine.
