This is a hydraulic seal kit designed to replace worn seals within the boom cylinder of Volvo excavators. It is manufactured to meet stringent OEM standards, ensuring a precise fit and reliable performance that surpasses degraded or leaking seals. Operators may notice slow or jerky boom movements, or a visible hydraulic fluid leak from the cylinder rod 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.
Initial signs of failure include a slight lag in boom response or minor external fluid seepage. If left unaddressed, the leak will worsen, leading to a gradual loss of hydraulic pressure and compromised lifting capacity. Continued operation with a failing seal kit can result in premature wear on other hydraulic components.
Thoroughly clean the cylinder bore and rod before beginning to prevent debris from damaging new seals. Ensure all seals are properly oriented before insertion to avoid immediate leakage.
Inspect the cylinder rod for any scoring or damage that may necessitate rod repair or replacement.
