This is a seal kit for the second boom cylinder on Volvo excavators, designed to maintain hydraulic system integrity. It is manufactured to meet stringent OEM standards, ensuring superior sealing performance compared to worn or damaged seals that can lead to leaks and reduced efficiency. Operators may notice a loss of boom control, slow operation, or visible hydraulic fluid leaks around the cylinder when this kit fails.

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 failure is often a visible hydraulic fluid leak around the boom cylinder. If ignored, the leak will worsen, leading to a gradual loss of lifting power and slower boom movement. Continued operation with leaking seals can result in system pressure loss and potential damage to other hydraulic components.
Ensure the cylinder rod is clean and free of any burrs or damage before installing the new seals. Avoid using sharp tools that could nick or cut the seals during installation.
Inspect the cylinder rod and bore for wear or damage, and check the hydraulic fluid level and condition.
