Frequently Asked Questions

What hydraulic cylinders fit a Case 550 dozer?

We carry blade angle, tilt, lift, and ripper cylinders that fit the Case 550 dozer. Many share fitment with the 450, 450B, and 450C, so matching the part number to your machine is the best way to confirm.

Do you sell seal kits to rebuild a Case 550 cylinder?

Yes. We offer hydraulic cylinder seal kits covering blade lift and multi-function cylinders for the 550, including USA made options. Verify the cylinder tube stamping or serial number, since some kits differ by piston design.

What tools do I need to rebuild a Case 550 hydraulic cylinder?

We carry spanner wrenches, gland seal installation tools, and complete cylinder rebuild tool kits for Case dozer cylinders. These help remove glands and seat new seals without damaging components.

How do I know which seal kit is correct for my 550?

Fitment can depend on piston type and serial number breaks, so match the cylinder tube stamping or the part number to your machine. If you are unsure, call our parts team at (800) 909-7060 to confirm.
