This is a comprehensive steering cylinder seal kit designed to restore the hydraulic integrity of your CAT steering system. It contains all necessary seals and O-rings manufactured from durable materials to prevent leaks and maintain proper hydraulic pressure, unlike a worn or cracked seal. Operators might notice slow or jerky steering response, or external fluid leaks around the cylinder when this kit is needed.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of failing steering cylinder seals is often a gradual loss of steering assist or a slight stiffness in the steering. If ignored, leaks will worsen, leading to more significant fluid loss and potentially complete loss of steering control. The risk is the inability to maneuver the machine safely, especially under load or on uneven terrain.
Thoroughly clean all internal surfaces of the cylinder barrel and piston rod before installing new seals to prevent damage. Ensure seals are correctly oriented and lubricated with appropriate hydraulic fluid to avoid tearing during installation.
Inspect the cylinder barrel and piston rod for any scoring or damage that could compromise the new seals' effectiveness.
