This is a boom cylinder seal kit specifically designed for the Volvo EC360 excavator. It contains all the necessary seals to rebuild the main boom cylinder, ensuring optimal hydraulic performance and preventing fluid leakage. A worn seal kit will manifest as slow or jerky boom movements, external hydraulic fluid leaks, and a diminished lifting capacity for the excavator.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of a failing boom cylinder seal kit is typically visible hydraulic fluid leakage from the cylinder rod. If left unaddressed, this leakage will increase, leading to a gradual loss of hydraulic pressure and resulting in slower, less responsive boom movements. The worst-case scenario is the boom cylinder's inability to hold its position under load, significantly impacting the excavator's operational safety and efficiency.
Ensure the cylinder bore is meticulously clean and free of any debris before installing the new seals to prevent premature failure. Avoid using excessive force or sharp tools that could damage the delicate sealing lips.
When replacing boom cylinder seals, it is advisable to inspect the hydraulic fluid and filter for any signs of contamination.
