Repair Support for Earthmoving and Construction Plant
At Hunter Valley Heavy Maintenance, we provide plant repairs in Newcastle for earthmoving and construction equipment, including excavators, backhoes, graders and bulldozers. Problems with an attachment, drive system or diesel component can take a useful machine out of service. We assess the symptoms and discuss the work needed to make an informed repair decision.
Plant repair has been part of our core diesel fitting work since the business began. Our team also draws on more than 20 years of industry experience.
We favour practical on-site assessment where safe and suitable, with further arrangements for work that cannot be completed there. For sudden faults, our breakdown repair service can help you make an initial enquiry at any hour.
Call (02) 3813 8835 to discuss the machine and fault.

From Fault Finding to a Repair Plan
Machines used in earthworks are exposed to demanding conditions. Assessing the failure before choosing a remedy helps avoid unnecessary part replacement.
- Excavator faults. Changes in movement, leaks or unusual noises call for diagnosis. We discuss the problem in the context of the machine's operation.
- Diesel & mechanical work. Engine and drivetrain issues may require detailed inspection. The findings help establish which work is appropriate.
- Welding & fabrication. Some repairs involve light fabrication or welding. Suitability depends on the damaged component and safe repair method.
- Return-to-work planning. Parts, access and the scope of work affect next steps. We explain what can reasonably be addressed and what requires further attention.
