This hydraulic tilt cylinder is engineered as a direct replacement for Bobcat OEM part numbers 6805512 and 6811612. It is designed for the right-hand bucket tilt function on Bobcat 873 and 883 skid steer loaders. The cylinder features a welded rod construction with a hardened chrome-plated rod to resist scoring and corrosion. The gland utilizes cast iron with buttress threads for improved thread strength and resistance to galling compared to aluminum alternatives. Key dimensional specifications include a bore diameter of 2.75 inches (69.85 mm) and a rod diameter of 1.625 inches (41.28 mm). The port configuration is SAE -8 JIC (3/4-16 UNF). The unit weighs approximately 46 lbs (20.9 kg). Cross-reference interchange numbers include WN-6811612 and casting number 170731. Verification of cylinder measurements prior to installation is recommended to ensure correct fitment for specific serial number breaks.
