Line boring in Bendigo

Bendigo VIC

What we see around Bendigo

Bendigo is an hour south of the workshop through Rochester and Elmore, and the work there looks different to the farm jobs closer to home. Civil earthmoving, quarries, mining and manufacturing, which means machines running hard five or six days a week that cost real money for every hour they are parked.

Sean spent a good part of his twenty years in mining and civil before setting up on his own, so this is familiar ground. Excavators and loaders on subdivisions and road works, dozers, skid steers, crushing and screening plant, and tipper and trailer hinge points all wear the same way. The pin goes first, then the bore, then the housing if nobody catches it.

Hire fleets are their own case. A machine that goes out to a different operator every fortnight racks up wear quickly and there is rarely a tidy window to pull it apart. We can work around the turnaround between hires, or take the component into the Wharparilla workshop while the machine stays on the yard.

What line boring actually does

Every pivot on a machine wears. Grease breaks down, dirt gets in, and the pin starts working the hole. What began as a round bore slowly goes oval, the pin loses its fit, and the play works its way through the whole linkage.

Line boring fixes that in place. A boring bar is set up through the worn hole and aligned to the original centreline, the bore is built back up with weld, then machined true to size so a standard bush and pin drops straight back in. The machine usually needs pulling down to get to the pivot. We can do that for you, or you can have it stripped and ready before we arrive.

Left too long, that play stops being a bore problem. It cracks weld seams, elongates the housing past repair and puts load through things that were never meant to carry it. Caught early, it is a day of work. Caught late, it is a new component.
