204-3615he00 Tilt Cylinder Seal Kit — Cat 320C

This is a tilt cylinder seal kit specifically designed for CAT excavators, responsible for maintaining hydraulic pressure and preventing leaks within the tilt cylinder assembly. It is manufactured to CAT's high-performance standards, ensuring consistent operation and longevity, unlike a worn kit that can lead to slow or jerky cylinder movement. Operators may observe a loss of tilt function, hydraulic fluid leaks around the cylinder, or a cylinder that drifts under load if this kit is required.

Installation & Application Notes

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.

Failure Symptoms

Visible hydraulic fluid leaks around the tilt cylinder rod or head are the primary indication of seal failure. This can progress to slow or erratic cylinder operation, with the bucket failing to hold its position under load. If left unaddressed, significant fluid loss can lead to system contamination and reduced hydraulic performance.

Installation Tip

Carefully inspect the cylinder rod for any burrs or damage that could compromise the new seals before assembly. Ensure all O-rings and backup rings are correctly seated to prevent extrusion.

Service Note

Inspect the hydraulic fluid for contamination and check the main hydraulic pump for proper pressure when replacing tilt cylinder seals.
