On-Site Line Boring That Saves Time

Line boring is all about precision—when a bore wears unevenly, it throws the whole system out of alignment. That means increased stress on components, faster wear and a higher risk of breakdowns. Our team uses industry-grade boring equipment that allows us to machine bores back to size and restore perfect alignment—all while the part stays in place. Whether you’re dealing with loader arms, excavator pins or any other pivot-based component, we deliver clean, true results that hold up in tough conditions.


  • Fully mobile boring setup with expert operators
  • Ideal for loaders, diggers, graders & farm gear
  • Suits urgent repairs & scheduled maintenance


We understand how essential your machinery is to your business. That’s why we offer 24/7 callouts and a straightforward, no-fuss approach.

Frequently Asked Questions

  • How do I know if my machine needs line boring?

    There are several signs to watch for. Excessive play in pivot points, uneven wear on bearings or bushings and irregular movement in components like arms, booms or buckets can all indicate a worn bore. In some cases, cracks or visible oval-shaped holes are obvious indicators. If left too long, the misalignment can damage nearby components and lead to more costly repairs. Regular inspection and early intervention are key to avoiding downtime.

  • Is line boring better than replacing parts?

    In many cases, yes. Replacing large components can be expensive and may involve lengthy lead times, especially for imported or older machinery. Line boring lets you restore the existing part on-site, often at a fraction of the cost of replacement. It also avoids the need for disassembly and transport, which saves time and labour. While some parts may eventually need replacement, line boring can significantly extend their usable life.

  • How long does a line boring job take?

    The timeframe depends on the size, number and condition of the bores being repaired. Simple jobs may be completed in a few hours, while more complex work could take a full day or longer. Mobile setups like ours streamline the process by eliminating the need for transport or dismantling. After assessing the damage, the operator will give you a realistic estimate before starting.
