Whether you need excavator pin boring, dozer repairs, or grader bush replacements, our certified technicians provide precision line boring services on-site or at our workshop.

What Is Line Boring?

Line boring is a precision machining process used to restore worn, elongated, or damaged bores in heavy machinery and earthmoving equipment. As pins and bushes wear over time, the bore becomes oval or oversized, causing excessive movement, vibration, and accelerated component failure. Line boring remachines the bore back to its original specifications, allowing a new pin or bush to be fitted at the correct tolerance.

Boring

Using specialised tools, we bore out the damaged sections, creating a new, smooth surface for the new bushings or sleeves.

Finishing

After boring, we finish the surface to the required specifications, ensuring a perfect fit for the replacement parts.

Quality Control

Each job undergoes rigorous quality checks to guarantee that all work meets industry standards.
