ZBXLB00072 — For Volvo Ec300D Arm Cylinder Seal Kit

This is an arm cylinder seal kit designed to maintain hydraulic system integrity in Volvo excavators. It is manufactured to strict OEM standards, ensuring superior sealing performance compared to worn or damaged seals that lead to leaks and reduced system pressure. Operators may notice slow or jerky arm movements, external hydraulic fluid leaks around the cylinder base, or a loss of lifting power when this kit fails.

Installation & Application Notes

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.

Failure Symptoms

External hydraulic fluid leakage around the arm cylinder rod is the first sign. If ignored, the leakage will worsen, leading to a gradual loss of hydraulic pressure and slower, less responsive arm movements. Continued operation with a failing seal kit can result in premature wear on cylinder components and potential system contamination.

Installation Tip

Thoroughly clean the cylinder bore and rod before installation to prevent damage to the new seals. Ensure all seal lips are properly lubricated and oriented correctly to avoid tearing during assembly.

Service Note

Inspect the cylinder rod for scoring or damage, and clean the hydraulic fluid reservoir for any debris before installing the new seal kit.
