Full Technical Description

560 256 16 CLUTCH ASSEMBLY This clutch assembly is responsible for transmitting torque from the hydraulic rotation motor to the drill steel. Located inside the drifter's rotation mechanism, it allows the operator to separate percussion from rotation. This function is crucial for collaring a hole accurately or when trying to free a stuck drill string without causing further jamming.

A worn or failing clutch directly impacts drilling efficiency. Symptoms often include weak or inconsistent rotation, especially under high load, which can significantly slow down your penetration rate. If the clutch starts to slip, it generates excess heat and can contaminate the hydraulic system with fine metal particles, leading to premature wear on other components.

Listen for any grinding or whining noises coming from the drifter, as this can indicate a problem with the clutch. This assembly is a wear item that is typically replaced during a major drifter overhaul. If you notice a sudden drop in rotational power, it is wise to schedule a service to prevent a complete failure in the middle of a shift.
