This seal kit is designed to replace worn seals within the arm cylinder of Volvo excavators, restoring proper hydraulic function and preventing fluid leaks. It is manufactured to meet stringent Volvo quality standards, ensuring a reliable seal that outperforms degraded original components. Operators may notice a loss of arm control, slow or jerky movements, or visible hydraulic fluid leaks when these seals begin to fail.
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 arm cylinder seal failure include slow or weak arm movement and minor hydraulic fluid seepage. If ignored, the leakage will worsen, leading to a significant loss of hydraulic pressure and control. Continued operation with severely degraded seals can result in unpredictable arm behavior, posing a risk to operational safety and efficiency.
Ensure the cylinder bore is meticulously clean before installing new seals to prevent damage and premature wear. Avoid using sharp tools that could nick or cut the seals during insertion.
Inspect the cylinder rod for any scoring or damage, and check the hydraulic fluid for contamination.
