Or call us now: 07 4763 0287
When a machine goes down on site, every hour costs you. Core Diesel's diesel technicians are experienced in diagnosing and repairing heavy earthmoving and civil machinery: excavators, dozers, graders, loaders, scrapers, and more, with full workshop capability and mobile field service anywhere on the Fraser Coast.
We work with civil contractors, agricultural operators, mining support companies, and hire businesses who can't afford extended downtime. From routine maintenance to major component replacements, our team has the tools, diagnostics, and experience to get machinery back into service fast.
We can bring the repair to the machine or bring the machine to us. Our mobile service vans are fully equipped for field diagnosis and repair anywhere on the Fraser Coast.
We use factory-level diagnostic tools across a wide range of heavy machinery brands, meaning faults are identified correctly the first time, not guessed at.
We rebuild and repair components in-house where possible: engines, hydraulics, transmissions, rather than defaulting to expensive full replacements.
Our technicians have hands-on experience with the heavy machinery used in civil construction, agriculture, forestry, and mining support. We know these machines.
Queensland Rail, JJ's Waste, Boral, Toll, Origin Energy, and Cleanaway trust Core Diesel with their heavy plant. We understand the pressure of commercial operations.
Call or book online. Tell us about the machine, the fault, and whether you need mobile attendance or can bring it to the workshop. We'll advise on the fastest path to repair.
We diagnose the fault using OEM-level tools and provide a clear quote before any work begins. No surprises.
We complete the repair to manufacturer specification, document the work with photos and video, and return the machine to service as quickly as possible.
