This is a hydraulic cylinder seal kit designed to restore the sealing integrity of the bucket cylinder on Volvo EC360 excavators. It is manufactured to meet stringent OEM standards, ensuring superior performance and durability compared to worn or damaged seals that lead to leakage and reduced hydraulic system efficiency. Operators may notice slow or jerky bucket movements, external hydraulic fluid leaks around the cylinder rod, or a loss of holding pressure when the bucket is extended.
Always verify with serial number before ordering.

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.
Initial signs of failure include slow bucket curl or dump functions and minor external fluid seepage from the cylinder rod. If ignored, the leakage will worsen, leading to a noticeable loss of hydraulic pressure and reduced lifting capacity. Continued operation with a failing seal kit can result in increased hydraulic system temperatures and potential damage to other hydraulic components.
Thoroughly clean the cylinder bore and rod before installation to prevent dirt from damaging the new seals. Avoid using sharp tools to pry seals into place, as this can easily cause nicks and tears.
Inspect the cylinder rod for any scoring or damage that may necessitate rod repair or replacement, and check the hydraulic fluid for contamination.
