This Arm Cylinder Seal Kit is essential for maintaining hydraulic system integrity by preventing fluid leaks and contamination within the excavator's arm cylinder. It features high-quality seals made from durable materials designed to withstand high pressures and harsh operating environments, outperforming worn or cracked original seals. Operators may notice a slow-moving or leaking arm, visible fluid around the cylinder rod, or a spongy feel in hydraulic controls when this 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 initial symptom of a failing arm cylinder seal kit is often a visible hydraulic fluid leak from the cylinder rod. If left unaddressed, the leak will worsen, leading to a loss of hydraulic pressure and sluggish arm movement. Continued operation risks significant hydraulic fluid loss and potential damage to the cylinder bore.

Installation Tip

Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage and ensure a proper seal. Avoid using sharp tools that could nick or cut the new seals during installation.

Service Note

Clean and inspect the hydraulic fluid reservoir and filter for contamination when replacing cylinder seals.
