Impact, mileage and harsh operating conditions strain engines, drivelines, steering and braking systems. Hidden faults increase fuel use, tyre wear and stopping distances, and can trigger costly breakdowns. Wales Heavy Vehicle Repairs delivers heavy vehicle mechanical repairs that return assets to peak condition. Using OEM procedures, quality parts and measured QA, we protect uptime, compliance and whole-of-life cost.
Engines, brakes, steering, driveline.
Passenger-safe braking and cooling.
Air brake and running gear service.
Hydraulics, cooling, powertrain checks.
Planned maintenance and repairs nationwide.
We combine specialist technicians, proven processes and modern tooling to deliver right-first-time outcomes and reduce cycle time.
Structured interview, road test where safe, fluid and visual checks. We document symptoms, service history and any collision context to guide diagnosis and scope.
You receive an itemised estimate covering labour, parts and consumables. We liaise with major insurers on authorisations and provide realistic delivery dates.
Mechanical, electrical and pressure tests confirm root causes. We use scan tools, pressure/vacuum gauges, leak-down and oscilloscope captures as required.
Engines, cooling, brakes, steering, suspension and driveline components are repaired or replaced to specification. Wear items and fasteners are renewed as required.
Correct fluids and specifications are applied. Critical fasteners are torqued to data. Belt tension, ride height and brake balance are set to manufacturer tolerances.
Adaptations and resets are completed for after-treatment, throttle, clutch, steering angle and EBS as applicable, ensuring systems operate as designed.
Controlled road test validates power, cooling, braking and steering. A second-person QA reviews work. You receive a clear summary and any preventive recommendations.
Repair and tune common-rail, injectors, pumps, EGR and intake systems for efficiency and reliability.
Service and balance service brakes, air supply, valves and EBS/ABS components for safe stopping performance.
Rebuild boxes, links, bushes, shocks and springs; set ride height for stability and tyre life.
Clutches, flywheels, tailshafts, diffs and hubs serviced or rebuilt to restore smooth power delivery.
Radiators, pumps, thermostats, charge-air coolers and A/C systems pressure-tested and repaired.
DPF, SCR and sensors tested, cleaned or replaced with required resets to maintain emissions compliance.
All in-house at major sites to reduce cycle time and maintain quality control.
Repairs follow OEM procedures with genuine or certified parts. Technicians are trained to current standards and sites are authorised by leading insurers. Fluids, torque values and calibrations are recorded. We never mask symptoms; recommendations are data-driven to keep assets compliant and operators protected.
Planned maintenance, SLA turnaround and consolidated invoicing support uptime and cash flow. National consistency across company-owned sites ensures the same methods, parts standards and documentation in Perth, Adelaide, Darwin, Melbourne, Sydney, Newcastle, Brisbane and Townsville. Milestone updates are provided from approval to QA.
