This is a seal kit specifically designed for the second boom cylinder on Volvo excavators, containing all necessary seals and O-rings to restore its functionality. It is manufactured from high-quality, durable materials to withstand hydraulic pressure and environmental factors, outperforming worn or damaged seals. Operators may notice hydraulic fluid leaks around the boom cylinder, a loss of lifting capacity, or slow/jerky boom movements 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 boom cylinder seal kit is typically visible hydraulic fluid leakage around the cylinder rod or barrel. If left unaddressed, the leakage will worsen, leading to a gradual loss of hydraulic pressure and reduced lifting performance. This can compromise the excavator's ability to hold loads or perform precise movements.
Carefully inspect the cylinder rod and bore for any nicks or scoring that could damage the new seals before assembly. Ensure all seals are properly seated and lubricated to prevent tearing during installation.
Inspect the hydraulic fluid for contamination and check the condition of the hydraulic hoses connected to the boom cylinder during seal kit replacement.
