This is a boom cylinder seal kit, designed to maintain the integrity of the hydraulic cylinder responsible for boom articulation on Volvo excavators. It comprises high-quality seals and wipers that prevent hydraulic fluid leakage and contamination ingress, ensuring smooth and powerful cylinder operation. A leaking or damaged seal kit will manifest as a slow-moving or drifting boom, visible hydraulic fluid loss, and potentially increased system temperature.
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 a failed boom cylinder seal kit is a noticeable drift or slow lowering of the boom when not actively being controlled. Continued operation will lead to increased hydraulic fluid loss and potential contamination of the hydraulic system. This can compromise the machine's stability and operational safety.
Thoroughly clean the inside of the cylinder bore and piston rod before installing new seals to prevent damage. Ensure all seals are properly seated and oriented according to the service manual to avoid immediate leakage.
Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid for signs of contamination or water ingress.
