This is a boom cylinder seal kit designed to maintain the integrity of the hydraulic boom cylinder on Volvo excavators, preventing fluid loss and ensuring smooth operation. It is constructed from durable materials to meet OEM standards, offering superior resistance to wear and pressure compared to compromised seals that lead to sluggish boom movement or external leaks. Operators may notice the boom drifting down under load, slow or jerky boom extension/retraction, or visible hydraulic fluid leaks around the cylinder.
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 boom cylinder seal kit include a slow drift of the boom when holding a position or a noticeable reduction in the speed and power of boom movements. If ignored, the leakage will increase, leading to a significant loss of hydraulic pressure, making it difficult to lift heavy loads and potentially causing overheating of the hydraulic system. Continued operation with compromised seals can lead to internal cylinder damage and costly repairs.
Thoroughly clean the cylinder bore and rod, removing all traces of old seal material and dirt, before fitting the new seals. Ensure the seals are correctly oriented and do not use excessive force or sharp objects that could damage them during installation.
Inspect the boom cylinder rod for scoring or pitting, and check the hydraulic fluid for contamination when replacing the boom cylinder seal kit.
