Frequently Asked Questions

What ignition switch fits a Case 850H dozer?

The Ignition Switch with Keys for Case Equipment (SKU 282775A1) fits a wide range of Case machines including the 850E through 850L series. Broken Tractor also carries ignition key sets like SKU 1964831C2 that cover 850G/H/K crawlers. Match the part number to your machine or confirm your model with the parts team before ordering.

Does the engine wiring harness fit a Case 850G dozer?

The Engine Wiring Harness (SKU 255899A1) fits the Case 850E and 850G dozers, but only those built before serial number JJG0254015. Harnesses on these machines have serial breaks, so check your serial number against that break before ordering. If you are unsure, confirm with our parts team.

What ignition switch fits a Case 850M or 1150M dozer?

The Ignition Switch with Keys for Case and New Holland Equipment (SKU 87416177) fits the newer M series crawlers including the 750M, 850M, 1150M, 1650M, and 2050M. Broken Tractor lists this switch by SKU so you can match it directly to your machine.

How do I know if I need an oil pressure switch or a temperature sender for my Case dozer?

An oil pressure warning or gauge issue points to the Oil Pressure Sensor Switch (SKU 277016A1), which fits models such as the 550H, 650H, 650K, 750H, 850H, and 1150H. A faulty temperature reading points to the Engine Temperature Sender Unit (SKU 84300765). We carry both, so match the sensor to the circuit that is failing.

What hour meter gauge fits a Case 1150C dozer?

The Hour Meter Gauge for Case Dozers and Loaders (SKU L107631) fits the 1150B, 1150C, 1150E, and 1150G among many other Case crawler models. It also covers the 450B through 850G range and larger 1450 and 1550 machines. Confirm your model against the fitment list or check the part number for your dozer.
