This seal kit is designed to replace the worn seals within the boom cylinders of various Volvo excavators and wheeled excavators, ensuring optimal hydraulic system performance. Manufactured to precise specifications, it offers superior durability and sealing capabilities compared to compromised original components. Operators may observe sluggish boom movement, external hydraulic fluid leaks, or a gradual loss of lifting power when these seals begin to deteriorate.
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 signs of failure include a noticeable lag in boom response or slight drifting when the cylinder is under load. Over time, external leaks may become visible, and the machine's overall hydraulic power will diminish. Ignoring these symptoms can lead to reduced productivity and potential damage to other hydraulic components.
Ensure all mating surfaces within the cylinder assembly are meticulously cleaned to prevent any grit from compromising the new seals. Carefully guide the seals onto the piston or rod to avoid tearing their delicate sealing lips.
Check the condition of the hydraulic fluid and filter, and inspect the cylinder rod for any imperfections that could damage the new seals.
