This is a boom lift cylinder seal kit, designed to replace the worn or damaged seals within the hydraulic cylinder responsible for boom elevation on Volvo loaders. It contains all necessary O-rings, wipers, and backup rings made from durable, high-performance materials to restore the cylinder's sealing integrity and prevent hydraulic fluid leakage. Operators will typically notice a slow-moving or drifting boom, external fluid leaks from the cylinder, or a loss of lifting capacity when these seals 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 failing boom cylinder seals is usually a visible hydraulic fluid leak around the cylinder rod or a noticeable drift or slow movement of the boom when not actively being controlled. If ignored, the leakage will worsen, potentially leading to a loss of hydraulic pressure and reduced lifting capacity. Continued operation risks hydraulic system contamination and potential damage to the cylinder bore.
Carefully clean the cylinder bore and piston rod before installing the new seals to prevent damage from debris. Ensure all seals are properly seated and lubricated with system-compatible hydraulic fluid before reassembly.
Inspect the hydraulic cylinder rod for scoring or damage, and clean or replace the hydraulic filter when replacing cylinder seals.
