This is a Boom Cylinder Seal Kit, essential for maintaining hydraulic system integrity and preventing fluid loss in heavy equipment. Manufactured to meet stringent OEM standards, it provides superior sealing and wear resistance compared to a worn or damaged kit. Operators may notice slow or jerky boom movements, external hydraulic fluid leaks around the cylinder, or a loss of lifting capacity 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 indication of a failing boom cylinder seal kit is often visible hydraulic fluid leaking externally from the cylinder rod. This can progress to sluggish or erratic boom operation and a reduced ability to hold loads. If left unaddressed, significant fluid loss can lead to hydraulic system failure and loss of equipment function.

Installation Tip

Carefully inspect the cylinder rod and bore for any scoring or damage before installing the new seals, as imperfections can quickly damage new seals. Ensure all sealing surfaces are clean and lubricated with system-compatible hydraulic fluid during installation.

Service Note

Inspect the hydraulic pump and hoses for leaks or damage when replacing the boom cylinder seal kit.
