This boom cylinder seal kit is designed to replace worn or damaged seals within the boom cylinder assembly of Volvo loaders, restoring its hydraulic integrity. It is manufactured to meet stringent material and dimensional standards, ensuring a tight seal that prevents fluid leakage and maintains optimal cylinder performance. Operators may notice a gradual loss of boom height, slow cylinder retraction, or visible hydraulic fluid leaks around the cylinder rod as signs of seal failure.
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 symptoms of a failing seal kit include slow or jerky cylinder movement and a slight loss of lifting capacity. If left unaddressed, the cylinder may fail to hold its position under load, leading to uncontrolled descent of the boom. This poses a significant risk to personnel and equipment if the boom is not properly supported.
Carefully inspect the cylinder rod for any nicks or scratches that could damage the new seals during installation. Ensure all old seal material is completely removed from the cylinder grooves before inserting the new seals.
Inspect the hydraulic fluid and filter for signs of seal degradation or contamination, and check the cylinder rod for scoring or wear.
