This is a hydraulic cylinder seal kit designed to replace worn or damaged seals within the boom cylinder assembly of Volvo excavators. It ensures the integrity of the hydraulic system by preventing fluid leakage and maintaining optimal pressure for smooth boom operation. Failure to replace worn seals can lead to gradual loss of lifting power and noticeable external leaks.
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 drift of the boom when not actively being operated. If ignored, the leakage will worsen, leading to reduced lifting capacity and potentially external fluid drips. Continued operation with severely degraded seals can compromise the hydraulic system's efficiency and require more frequent fluid top-offs.
Thoroughly clean the cylinder bore and rod before installation to prevent debris from damaging the new seals. Ensure all seals are properly seated and oriented before reassembling the cylinder components.
Inspect the cylinder rod for any scoring or damage that could compromise the new seals' performance.
