DROP GEAR

710 810 93 TRANSFER GEAR BOX Located inside the gearbox of the rock drill, this DROP GEAR is responsible for changing the direction of rotational power. It takes the input from the rotation motor and converts it into the high-torque output needed to turn the drill string. Proper gear mesh is essential for delivering consistent power to the bit and achieving good penetration rates.

A worn or damaged gear can significantly impact drilling operations. Symptoms often start with excessive backlash or play in the rotation, leading to erratic movement and potentially causing the drill string to get stuck. If a gear tooth breaks, the entire rotation mechanism can lock up, resulting in an immediate and costly stoppage.

Listen for unusual grinding or whining noises from the drifter, as this can indicate advanced gear wear. When you change the gearbox oil, check for an abnormal amount of metal particles. For best results, it is highly recommended to replace the DROP GEAR and its mating pinion as a matched set to ensure correct contact and prevent premature failure.
