This is a seal kit designed to replace worn seals within the boom cylinder of Volvo excavators, ensuring proper hydraulic pressure retention and smooth operation. It is manufactured to meet stringent material and dimensional standards, providing superior sealing performance compared to degraded or damaged original seals. Operators may notice slow or jerky boom movements, or a loss of lifting capacity when these seals begin to fail.
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 seal failure is often a slow drift of the boom when holding a position. If ignored, the cylinder may begin to leak externally, and the machine's hydraulic performance will noticeably degrade. Continued operation with failing seals can lead to increased cycle times and reduced operational efficiency.
Thoroughly clean the cylinder bore and rod before beginning to prevent contaminants from damaging the new seals during installation. Avoid using sharp tools that could nick or cut the seal lips.
Inspect the hydraulic fluid for contamination and consider replacing the hydraulic filter when servicing the boom cylinder seals.
