Maintenance Tip: Addressing Low Rotation Torque on Epiroc SmartROC D65

A common operational fault in Epiroc SmartROC D65 drill rigs is significantly reduced or intermittent rotation torque, which can severely impact penetration rate. If hydraulic system pressures are confirmed, the fault often resides in the rotation unit's control or sealing elements.

Processing Plan:

• Check Valve Function: Inspect the rotation control valve. If sticky or failing, the 89538029 VALVE should be replaced. A faulty valve prevents proper flow distribution to the rotation motor.

• Seal Integrity: Low torque can be caused by internal leakage within the rotation motor. The 89556219 SHAFT SEAL is a critical component here. Replace this seal along with other relevant components found in the 89576559 REPAIR KIT to restore peak efficiency.

• Data Check: Post-repair, ensure the rotation pressure stabilizes at the manufacturer's specified maximum (e.g., 200 bar) for the rotation circuit.

Using high-grade Hugeminer seal kits ensures lasting performance, preventing recurrence of this common hydraulic issue.
