This is a boom cylinder seal kit designed to maintain the integrity and performance of the main boom hydraulic cylinder on Volvo excavators. It contains high-quality seals and wipers manufactured to strict standards, which are essential for preventing hydraulic fluid leaks and contamination that would occur with worn or damaged seals. Operators may notice a slow drift of the boom when the cylinder is lowered or a loss of lifting power if these seals fail.
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 indication of boom cylinder seal failure is often a visible hydraulic fluid leak around the cylinder rod or a slow, uncontrolled lowering of the boom when the machine is idle. If ignored, the cylinder may lose significant lifting capacity, and internal contamination can accelerate wear on other hydraulic components, impacting overall machine performance.
Thoroughly clean the cylinder bore and piston rod before installing the new seals to prevent damage and ensure a proper seal. Be careful not to nick or cut the new seals during installation, especially the rod seal, as this is a common point of failure.
Inspect the cylinder rod for pitting or scoring, and check the hydraulic fluid for signs of contamination or water ingress when replacing boom cylinder seals.
