3. Disassemble the Cylinder Once the boom cylinder is detached, carefully disassemble it. Remove the end caps, which may require a specific tool or technique depending on your excavator model. Take care not to damage any internal components.

2. Keep Contaminants Out Dust, dirt, and other foreign particles can cause severe damage to machinery. Oil seals act as barriers, keeping these contaminants from entering and prolonging the life of the equipment.

In addition to preventing leaks, the oil seal also plays a role in protecting the hydraulic system from contaminants. Dust, dirt, and debris can easily enter the hydraulic system without a proper seal, leading to wear and tear on the components and potentially causing the system to malfunction. The oil seal creates a barrier between the internal components of the cylinder and the external environment, ensuring that the hydraulic system remains clean and efficient.

3. Pressure Maintenance Hydraulic systems rely on maintaining a specific pressure to function effectively. Oil seals help retain this pressure by providing a secure barrier that prevents fluid escape, which is crucial for optimal motor performance.
