COP 1022 HF- 8311 1022 28 Located within the main body of the rock drill, this component plays a crucial role in managing the flow and pressure of hydraulic oil. It ensures that separate circuits, like the one for the impact mechanism and the one for the rotation motor, remain isolated and operate at their specified pressures. Proper function is fundamental to converting hydraulic power into mechanical drilling force.

Degradation of this part leads directly to a loss of drilling performance. An internal leak past a worn seal, for example, means the impact piston doesn't receive full hydraulic pressure, resulting in slower penetration rates and increased wear on other components. Maintaining its integrity is key to preventing unplanned downtime and ensuring the drifter operates reliably shift after shift.

Common signs of failure include visible oil drips from the drifter housing or a noticeable decrease in drilling power. During a scheduled service or rebuild, always inspect this component for wear or damage. When installing a replacement, make sure the surrounding surfaces are perfectly clean and lubricated to prevent premature failure.
