Frequently Asked Questions

What hydraulic cylinders are on a Cat dozer?

Cat D-series dozers use blade lift, blade tilt and blade angle cylinders, and machines with a rear ripper also use ripper cylinders. Broken Tractor carries all four cylinder types for a wide range of Cat dozers, from the D3 series up through the D11N, D11R and D11T. Which cylinders your machine has depends on its model and blade setup.

How do I find the right hydraulic cylinder for my Cat D6 dozer?

Start with your dozer's serial number and blade configuration (SU, U, S or PAT), because cylinder fitment changes with both. Models like the D6, D6C, D6H, D6R and D6T can use different cylinders depending on these details. The safest approach is to match the part number from your existing cylinder or confirm fitment with the Broken Tractor parts team at (800) 909-7060 before ordering.

Should I rebuild or replace a leaking hydraulic cylinder on a Cat dozer?

A leaking or worn cylinder can often be rebuilt, and Broken Tractor offers seal kits for most Cat dozer cylinder assemblies. If the cylinder needs more than new seals, we also carry individual components such as pistons and rods, as well as complete cylinder assemblies. Matching the kit or part to your cylinder's part number helps make sure everything fits.

Are new or remanufactured hydraulic cylinders offered for Cat dozers?

Broken Tractor offers both new and remanufactured cylinder options, depending on the Cat dozer model. Options vary across machines such as the D4H, D5M, D7G, D8K and D9L, so the choice depends on your specific model and cylinder type. Confirm your serial number and blade configuration first so you get the correct cylinder in either condition.

Which Cat dozer models do you carry hydraulic cylinders for?

Broken Tractor carries hydraulic cylinders and cylinder parts for Cat D3, D4, D5, D6, D7, D8, D9, D10 and D11 series dozers. Coverage includes older machines like the D4D, D6C and D8H as well as later models like the D6T, D8T, D9T and D10T. Orders get fast shipping from our Baton Rouge, LA and Kimbolton, OH locations.
