Our Services

Mobile Line Boring

B-TECH LINE BORING provides a mobile line boring service to Sydney, Newcastle, Hunter Valley, Central Coast, Wollongong and regional NSW areas.

Mobile onsite line boring is required to repair damaged, cracked, oversized or worn out bores and bore faces on a vast range of mining and civil earthmoving and construction machinery. This service is ideal when the bore needs to be repaired but the machine is too large, or it is too inconvenient to be transported to a workshop.

We use our own custom-designed line boring set up that can weld the bore whilst the machining process is operating simultaneously. This system is capable of welding, facing and boring up to 400mm diameter to the tightest tolerance in accordance with manufacturers specifications.

We can ID bore weld and machine worn components on a vast range of machinery including but not limited to:

  • Franna Crane

  • Crawler Crane

  • Excavator

  • Bulldozer

  • Front End Loader

  • Dump Truck

  • Wheel Dozer

Liquid Nitrogen Freeze Fitting

B-TECH LINE BORING provides a mobile liquid nitrogen freeze fitting service to the Sydney, Newcastle, Hunter Valley, Central Coast and Wollongong areas.


This service is required when there is a need to install bushes, pins and bearings with an interference fit. This eliminates the need to press-fit therefore speeding up the repair process.
