This is a boom cylinder seal kit, designed to replace worn seals within the hydraulic cylinder responsible for boom articulation on Volvo excavators. It utilizes high-quality NBR rubber and metal components to prevent hydraulic fluid leakage and maintain optimal cylinder performance. Leaking seals will manifest as slow or jerky boom movement and visible hydraulic fluid around the cylinder rod.
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 primary symptom of failing boom cylinder seals is visible hydraulic fluid leakage from the cylinder rod or casing. This will progress to slower, less responsive boom operation and potential 'drift' when the boom is held in position. Continued operation with leaking seals can lead to internal cylinder damage and loss of hydraulic pressure.
Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage from debris. Ensure all seals are properly oriented according to the kit's instructions to prevent immediate failure.
Inspect the hydraulic fluid for contamination and consider replacing the hydraulic filter when servicing the boom cylinder.
