This is a seal kit specifically designed for the boom cylinder of Volvo excavators and related models, crucial for preventing hydraulic fluid leakage and maintaining system pressure. Manufactured to meet demanding Volvo standards, it offers superior sealing capabilities over worn or damaged seals that can lead to performance degradation. Operators may observe external hydraulic fluid leaks from the cylinder rod or a noticeable decrease in lifting capacity when these seals begin to fail.

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 most common initial symptom is visible hydraulic fluid leaking from around the boom cylinder rod. If left unaddressed, the leaks will increase, leading to a gradual loss of hydraulic pressure and reduced lifting performance. Continued operation can result in significant fluid loss and potential damage to the hydraulic system components.
Carefully clean the cylinder bore and rod before installing the new seals to prevent any dirt or debris from causing damage. Ensure the seals are oriented correctly and seated fully without being twisted or nicked during installation.
Inspect the boom cylinder rod for any signs of scoring or wear that could compromise the new seals' performance.
