Excavator Repairs Newcastle

Common issues include hydraulic system failures, worn undercarriage components, engine faults, and electrical malfunctions. Our focus when assessing any fault is accurate diagnosis before work begins. 

Hydraulic failures are among the most frequent problems across the industry, often caused by contaminated oil, and can present as slow or weak operation, leaking hoses, or poor ram performance. 

Worn tracks, sprockets, and rollers are also common, particularly on machines operating on rough terrain. Engine faults may present as overheating, reduced power output, or excessive exhaust smoke, often linked to fuel system issues or blocked filters.

Typical signs include sluggish movement, weak lifting capacity, visible leaks from hoses or fittings, and unusual noises coming from the hydraulic pump. Hydraulic failures are often caused by contaminated oil or degraded seals and hoses.

If you notice any of these symptoms, you can trust our experts to inspect the machine and give you a clear assessment before the fault develops further and causes more extensive damage to hydraulic components.

Undercarriage maintenance addresses wear and tear on the tracks, rollers, idlers, and sprockets caused by ground engagement. Incorrect track tension is one of the more common contributors to accelerated undercarriage wear, so tension checks are a standard part of any undercarriage inspection.

Our team has the skills and expertise to assess the overall condition of undercarriage components, and all repair work is completed to a high standard to keep the machine running properly.

Engine faults typically present as overheating, loss of power, difficulty starting, or excessive exhaust smoke. Overheating is often linked to blocked radiators or low coolant levels, while smoke can indicate underlying fuel system issues or filter blockages.

No matter the cause, our team has the experience to diagnose engine problems accurately and carry out the necessary repairs to keep the machine operating safely on site.

Service intervals vary depending on the make and model, operating conditions, and machine hours. As a general guide, most excavators require a service every 250 to 500 hours of operation, though manufacturers' schedules should always be followed.

For any business operating excavators, a preventative maintenance program is recommended to minimise unplanned downtime and extend the working life of the machine. Our highly skilled mechanics have extensive experience with scheduled servicing across a range of makes and models, and can help identify developing faults before they become significant problems.
