170-9829 Bucket Cylinder Seal Kit — Cat 3196 365B

This bucket cylinder seal kit provides all necessary seals and O-rings to rebuild a leaking hydraulic cylinder, essential for the proper functioning of the bucket's lifting and tilting mechanisms. Manufactured to meet OEM specifications, these seals offer superior resistance to wear and hydraulic fluid degradation compared to worn or brittle seals. Operators will typically observe hydraulic fluid leaks around the cylinder rod, slow or jerky bucket movements, or a loss of holding pressure when the cylinder is extended.

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 from the bucket cylinder rod are the primary indicator of seal failure. If ignored, the leaks will worsen, leading to a gradual loss of hydraulic pressure and slower, less responsive bucket control. Continued operation with leaking seals can allow contaminants into the hydraulic system, potentially damaging other components.

Installation Tip

Carefully inspect the cylinder rod and bore for any nicks or scoring before installing the new seals, as imperfections can cause immediate failure. Ensure all seals are properly seated and lubricated with appropriate hydraulic fluid to prevent damage during installation.

Service Note

Inspect the hydraulic fluid level and condition; consider replacing the hydraulic filter after cylinder repair.
