This boom lift cylinder seal kit is essential for maintaining the integrity of the boom lift cylinder, preventing hydraulic fluid leaks and ensuring smooth operation of the loader's lifting functions. Manufactured to Volvo's rigorous specifications, these seals offer superior resistance to wear and pressure compared to degraded seals that can cause sluggish lifting or drifting. Operators may notice slow boom movement, inability to hold a load at a specific height, or hydraulic fluid leaks around the cylinder rod when this kit is needed.
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 initial symptom of failing boom lift cylinder seals is often a slow leak of hydraulic fluid from around the cylinder rod or a gradual loss of lifting height when the engine is off. If ignored, the leaks will increase, leading to reduced lifting capacity, slower boom operation, and potential overheating of the hydraulic system. Continued operation with leaking seals can cause damage to the cylinder bore and piston, leading to more costly repairs.
Clean the cylinder bore and piston rod meticulously before installing the new seals to prevent contamination and ensure a tight seal. Be careful not to nick or damage the new seals during installation.
Inspect the boom cylinder rod for any signs of pitting or damage, and check the hydraulic fluid for contamination before replacing the seal kit.
