Frequently Asked Questions

What is the difference between a bare cylinder head and a loaded cylinder head?

A bare head is the casting alone, while a loaded head comes assembled with valves and springs installed. Broken Tractor carries both options for Case dozers running Cummins engines, including the loaded head under SKU J930913 and the new head with valves under SKU J938656. Choose a loaded head if you want to avoid transferring valvetrain parts from your old head.

Which cylinder head fits a Case 850D dozer?

The Cummins 6.590 cylinder head under SKU J930912 fits the 850D, along with the 850E, 850G, 855D, and 855E. The new 6B / 6BT head under SKU J938656 also covers the 850D and 855D. Because fitment depends on the exact engine series, match the part number to your machine or confirm with our parts team before ordering.

Do you carry cylinder heads for a Case 1150E dozer?

Yes, the Cummins 6.590 head under SKU J930912 fits the 1150E along with the 1150G and 1155E. The 6B / 6BT head under SKU J938656 also lists the 1150E when equipped with the 6T590 engine. Confirm your engine series so the correct head is matched to your dozer.

Do I need a head gasket set and head bolts when replacing a cylinder head?

Most head replacements call for a fresh upper gasket set and new head bolts. Broken Tractor offers the Upper Head Gasket Set for Cummins 6B590 and 6BT590 engines under SKU 3804897, a Cummins head gasket set under SKU 3804896, and head bolt sets under SKU RP731134 and SKU RP731141. Match the gasket and bolt set to your engine series so the parts line up with your head.

Do you sell used cylinder heads for Case dozers?

Yes, Broken Tractor carries both new and used cylinder heads for Case dozers running Cummins engines. The used loaded head with valves and springs is offered under SKU J930913U. Cummins fitment is verified before every sale, so confirm the part number matches your engine series.
