This cylinder seal kit is essential for maintaining the integrity of the hydraulic cylinder in Volvo excavators, preventing internal and external leaks of hydraulic fluid. It is manufactured using durable materials that withstand high pressures and temperatures, offering superior sealing compared to worn or brittle original seals. Operators may observe hydraulic fluid leaks around the cylinder rod, a loss of lifting or digging power, or a cylinder that drifts or fails to hold its position if this seal kit is compromised.
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.
Visible hydraulic fluid leaks around the cylinder rod are the most common initial symptom of a failed seal kit. If ignored, this leakage will worsen, leading to a noticeable loss of hydraulic pressure and power in the affected cylinder's function. The ultimate consequence is the inability of the cylinder to hold its position or perform its intended task, potentially immobilizing the equipment.
Always lubricate the seals with clean hydraulic fluid or a compatible lubricant before installation to prevent tearing and ensure proper seating. Avoid using sharp tools that could scratch the cylinder bore or damage the delicate sealing lips.
Inspect the cylinder rod for scoring or pitting, and check the internal cylinder surfaces for wear or damage before installing the new seal kit.
