This seal kit is engineered to replace the worn seals within the boom cylinder of Volvo excavators, preventing hydraulic fluid leaks and maintaining optimal lifting performance. It is manufactured to meet stringent OEM standards, offering superior resistance to wear and pressure compared to compromised original seals. Operators may observe slow or jerky boom movements, external fluid leaks from the cylinder, or a loss of lifting capacity if 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.
External hydraulic fluid leaks originating from the boom cylinder rod seal are the initial indication of failure. If left unaddressed, these leaks will increase, leading to sluggish or inconsistent boom extension and retraction. The ultimate consequence is a compromised ability to hold loads and potential internal cylinder damage.
Carefully inspect the cylinder rod for any nicks or scratches that could damage the new seals during installation. Ensure the new seals are properly seated and not twisted before reassembling the cylinder.
Inspect the cylinder rod for scoring and check the hydraulic fluid for signs of contamination.
