The function of the shuttle in the external main valve chamber is to direct fluid flow in the system. In hydraulic systems, the shuttle acts as a crucial component that allows the operator to manage and control the distribution of hydraulic fluid to various parts of the system. This is essential for ensuring that the hydraulic actuators or attachments receive the appropriate flow to function effectively.

Directing fluid flow involves allowing or blocking the passage of hydraulic fluid to specific areas based on operational needs. By performing this role, the shuttle helps maintain effective system performance and safety, preventing issues that could arise from incorrect fluid routing. Understanding the function of the shuttle is vital for technicians, as it contributes to the efficient operation of hydraulic systems in Yamaha equipment and ensures that various functions—such as lifting, lowering, and steering—are executed properly.
