This is a boom cylinder seal kit for Volvo excavators, designed to replace worn seals within the boom cylinder, ensuring proper hydraulic pressure retention and preventing fluid leakage. It is constructed from high-quality, durable materials that resist wear and chemical breakdown, offering superior performance compared to degraded seals that lead to cylinder drift or sluggish operation. Operators may notice the boom slowly drifting down when not actively engaged, or a reduction in the speed and force of 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 often a slow, uncontrolled drift of the boom when the hydraulic controls are not activated. If left unaddressed, the cylinder will lose significant lifting capacity and responsiveness, making precise operation difficult and potentially unsafe. Continued operation with leaking seals can lead to internal cylinder damage and contamination of the hydraulic fluid.
Thoroughly clean the cylinder bore and piston rod, inspecting for any scratches or imperfections that could damage the new seals. Ensure the new seals are properly lubricated before installation to prevent tearing.
When replacing the boom cylinder seal kit, inspect the cylinder rod for pitting or scoring and check the hydraulic fluid and filters for contamination.
