TERMINAL BUSHING

803 072 29A TERMINAL BUSHING Acting as a sacrificial bearing, this bushing provides a low-friction surface between a pin and its housing, typically found in the boom or feed system linkages. It absorbs shock loads and maintains tight tolerances in critical joints, allowing for precise and controlled movement of the drilling unit.

When a bushing wears out, it creates excessive play in the joint. This looseness can make it difficult to accurately position the feed beam, slowing down the entire drilling cycle. Over time, this misalignment puts extra stress on pins, bearings, and even the main steel structures, leading to more costly repairs down the line.

A common sign of a failing bushing is a clunking sound during movement or visible looseness in a pivot point. During routine inspections, check for any play in the joints. Replacing worn bushings promptly is essential to protect more expensive components and maintain drilling accuracy.
