This seal kit is designed to replace the worn seals within the boom cylinder of Volvo excavators, ensuring proper hydraulic fluid containment and smooth operation. Manufactured to meet stringent OEM standards, it provides reliable sealing and durability, unlike degraded original seals that can lead to leaks and performance issues. Operators may notice external fluid leaks from the cylinder, slow or jerky boom movements, or a reduction in lifting capacity if 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.
Visible hydraulic fluid leaks around the boom cylinder rod are the first sign of seal failure. If left unaddressed, these leaks will worsen, leading to decreased hydraulic pressure and slower, less responsive boom movements. The consequence is a reduced ability to perform tasks and potential internal damage to the cylinder.
Carefully inspect the cylinder rod for any imperfections that could damage the new seals during installation. Ensure that the seals are seated correctly and not twisted before reassembling the cylinder.
Inspect the cylinder rod for scoring or pitting, and check the hydraulic fluid for contamination.
