What line boring fixes
Pins and bushings on earthmoving equipment wear unevenly over time, leaving the bore out of round or out of alignment. A worn bore causes play in the joint, which leads to faster wear everywhere else in the assembly. Line boring corrects this by machining the bore back to a true, accurate diameter.
Our line boring equipment uses a hydraulic-driven boring bar with a carbide tip, operating like a portable lathe fitted directly to the component. We can repair holes from 40mm to 350mm in diameter.

Frequently Asked Questions
What size bores can you repair?
From 40mm to 350mm in diameter.
Why does a bore need to be machined rather than just re-welded?
Welding alone won't bring a worn bore back to a true, round shape — machining after the weld build-up is what restores the correct fit and tolerance.
Can you line bore at my site?
No — line boring is carried out at our Ravenhall workshop. Drop the component off or arrange freight.
