Full Technical Description

550 874 14 CABLE ENTRY PLATE Located deep inside the drifter body, this plate acts as a central bulkhead, separating and aligning critical moving parts. It provides a stable mounting face for bearings and gears within the rotation gear train, ensuring that shafts and other components remain perfectly positioned during the intense vibration of drilling.

Wear or damage to this plate can have serious consequences for the entire drifter. For example, if the bearing seats become worn, the resulting gear misalignment will quickly lead to excessive noise, loss of rotation torque, and ultimately, catastrophic failure of the gear train. Maintaining its integrity is key to the drifter's long-term reliability and drilling performance.

During a full drifter rebuild, always check this plate for flatness and any signs of fretting or wear on its machined surfaces. If you find any visible damage or scoring, replacing the plate is necessary to protect your investment in new gears and bearings.
