This is an arm cylinder seal kit designed to replace worn seals within the hydraulic arm cylinder of Volvo excavators. It restores the cylinder's ability to hold pressure and prevent hydraulic fluid leaks, ensuring smooth and efficient boom and arm operation. Worn seals will manifest as slow or jerky arm movements, and external fluid leaks around the cylinder rod.
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 symptoms include a slight drift in the arm when holding a position or a minor external hydraulic fluid leak from the cylinder rod. If left unaddressed, the arm may become sluggish, lose lifting capacity, and the hydraulic system may experience increased contamination from external debris entering the cylinder.
Thoroughly clean the cylinder bore and piston rod before installing new seals to prevent damage and ensure a proper seal. Avoid using sharp tools that could nick or scratch the sealing surfaces.
Inspect the hydraulic fluid for contamination and check the condition of the hydraulic pump when replacing arm cylinder seals.
