This is a comprehensive seal kit designed to replace all the necessary seals within the boom cylinder of your Volvo excavator, restoring its hydraulic integrity and preventing fluid loss. Manufactured to meet rigorous Volvo standards, these seals offer superior resistance to wear, heat, and hydraulic fluid degradation compared to worn or damaged seals. Operators will typically notice hydraulic fluid leaks around the boom cylinder, or a loss of lifting capacity and slow boom movement if the seals have failed.
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 failing boom cylinder seals is often visible hydraulic fluid leakage around the cylinder rod or at the cylinder base. If ignored, the leakage will worsen, leading to a gradual loss of lifting force and slower, less responsive boom operation. Continued operation with leaking seals can lead to internal cylinder damage and contamination of the hydraulic system.
Thoroughly clean the cylinder bore and piston rod before installing new seals to prevent contamination and damage. Ensure all seals are properly seated and lubricated with clean hydraulic oil to prevent tearing during installation.
Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid for contamination before installing the new seal kit.
