This is a comprehensive seal kit specifically designed for the arm cylinder of Volvo excavators, containing all necessary seals and O-rings to rebuild the hydraulic cylinder. It is manufactured to meet precise OEM specifications, ensuring a leak-free seal and proper cylinder function, unlike a worn or damaged kit. Operators may notice hydraulic fluid leaks around the arm cylinder, sluggish or jerky arm movements, or a loss of holding pressure in the arm when this seal kit fails.
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.
The first sign of a failing arm cylinder seal kit is typically visible hydraulic fluid leakage around the cylinder rod or barrel. If ignored, the leakage will worsen, leading to a loss of hydraulic pressure and slower, less precise arm movements. Continued operation with leaking seals can lead to internal cylinder damage and contamination of the hydraulic system.
Thoroughly clean all internal surfaces of the cylinder bore and piston before installing new seals. Ensure all new seals are properly lubricated with compatible hydraulic fluid to prevent tearing during installation.
Inspect the cylinder rod for scoring or damage and the cylinder bore for wear before installing the new seal kit; re-chroming or honing may be necessary.
