This is an arm cylinder seal kit designed to maintain hydraulic pressure and prevent fluid leakage within the arm cylinder assembly of Volvo excavators. It is manufactured to meet stringent OEM quality standards, ensuring superior sealing performance compared to worn or damaged seals that lead to gradual pressure loss and reduced cylinder responsiveness. Operators may notice slow or jerky arm movements, external hydraulic fluid leaks around the cylinder rod, or a loss of digging force 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.
Early indications of a failing arm cylinder seal kit include a slight delay in arm extension or retraction. If left unaddressed, this will progress to visible hydraulic fluid leaks around the arm cylinder rod and a noticeable decrease in the excavator's digging force. Continued operation can accelerate wear on the cylinder components and potentially lead to contamination of the hydraulic system.
Thoroughly clean the cylinder bore and rod to remove any debris or old seal fragments before installing the new seals. Ensure the new seals are lubricated with clean hydraulic fluid to prevent tearing during installation.
Inspect the arm cylinder rod for scoring and ensure the hydraulic fluid is clean and at the correct level before installing the new seals.
