244-0980 Hydraulic Cylinder Seal Kit — Cat D6T

This is a hydraulic cylinder seal kit, designed to replace all the necessary seals within a hydraulic cylinder to restore its sealing capabilities. Manufactured to meet rigorous OEM standards, this kit ensures a tight seal and smooth operation, unlike a worn kit where leaks and reduced performance are evident. Operators might observe external fluid leaks from the cylinder, slow or jerky cylinder movement, or a loss of holding pressure when this seal kit fails.

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

The first sign of a failing seal kit is often visible hydraulic fluid leakage around the cylinder rod or head. If left unaddressed, the leakage will worsen, and the cylinder may lose its ability to hold pressure, leading to slow or uncontrolled movement. Continued operation with leaking seals can lead to contamination of the hydraulic system and potential damage to the cylinder rod and bore.

Installation Tip

Always inspect the cylinder rod and bore for scoring or damage before installing new seals, as imperfections will cause premature seal failure. Ensure all old seal material is completely removed from the grooves before inserting the new seals.

Service Note

When replacing a hydraulic cylinder seal kit, it is advisable to inspect the hydraulic fluid for contamination and consider flushing the system if necessary.
