This boom cylinder seal kit is essential for maintaining the integrity of the hydraulic cylinder, preventing internal and external fluid leakage. It is manufactured to Volvo's robust standards, ensuring a tight seal and smooth operation, unlike a worn kit that would allow oil bypass and cylinder drift. Operators may notice the boom slowly lowering when holding position, or a visible hydraulic fluid leak around the cylinder rod as indicators of a failed seal kit.
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 a failing boom cylinder seal kit is often noticeable cylinder drift, where the boom slowly lowers under its own weight when the hydraulic control is in neutral. If ignored, internal leakage will increase, leading to reduced lifting capacity and potential overheating of the hydraulic fluid. Continued operation with leaking seals can cause scoring of the cylinder rod and bore, leading to more extensive and costly repairs.
Thoroughly clean the cylinder bore and rod before installing new seals to prevent contamination from damaging the new components. Ensure all seals are properly seated and lubricated according to the service manual to prevent tearing during assembly.
Inspect the cylinder rod for scoring or damage, and clean or replace the hydraulic fluid and filter if contamination is suspected.
