This is a boom cylinder seal kit designed for Volvo excavators, providing all the necessary seals and O-rings to effectively rebuild the hydraulic boom cylinder. Manufactured to meet stringent OEM quality standards, it ensures a reliable seal against internal and external leaks, maintaining optimal boom operation. Operators may observe hydraulic fluid leaking from the boom cylinder, a noticeable drop in boom lifting capacity, or the boom slowly drifting down when the machine is not in operation 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.
The initial symptom of a failing boom cylinder seal kit is usually external hydraulic fluid leakage around the cylinder. If left unaddressed, this leakage will increase, resulting in a loss of lifting power and the boom slowly drifting downwards. Continued operation with compromised seals can lead to internal cylinder damage and contamination of the hydraulic fluid.
Before installing, carefully inspect the cylinder rod for any nicks, scratches, or wear that could damage the new seals. Use a suitable lubricant on all seals and the cylinder bore to ease installation and prevent damage.
Check the condition of the cylinder rod and bore for any signs of scoring or wear; if damaged, the cylinder may require honing or re-chroming before installing the new seals.
