Mobile & Workshop Excavator Servicing, Diagnostics & Repairs

Slow, weak or jerky boom, arm, slew or bucket operation can indicate low hydraulic pressure, leaking hoses or cylinders, worn pumps or control valve faults. We pressure-test the system and repair or replace components onsite or at our Brendale workshop. 

If your excavator cranks slowly, will not start, starts intermittently or cuts out while operating, we can test the batteries, starter and charging system, wiring, sensors, fuel supply and engine-management system to identify the actual cause. 

Loss of digging power, stalling under load or black, white or blue smoke can point to blocked air intake, turbocharger faults, worn injectors, poor fuel delivery or internal engine wear. We diagnose the cause before quoting the most suitable repair. 

Dust, mud and debris can block radiators, oil coolers and intercoolers. Coolant leaks, damaged hoses, failed thermostats, belts, fans and water pumps can also cause overheating. We inspect the cooling system to help prevent costly engine damage. 

Contaminated diesel, blocked filters, air entering the fuel system, worn injectors and failing pumps can cause rough running, hard starting, excessive smoke and reduced power. We inspect and test the fuel system before recommending replacement parts. 

Warning lights, fault codes, intermittent shutdowns and failed controls can be caused by damaged wiring, poor connections, sensors, controllers, batteries or charging faults. We use diagnostic equipment and electrical testing to trace the fault accurately. 

An excavator that tracks slowly, pulls to one side, makes unusual noises or loses travel may have a final drive, travel motor, brake or hydraulic supply fault. We test the system to determine whether repair, resealing or component replacement is required. 

Blocked DPFs, EGR faults and failed pressure or temperature sensors can cause warning lights, unsuccessful regenerations, engine derates and reduced performance. We diagnose compliant emissions-system faults and replace failed components.

Worn excavator tracks, rollers, bucket pins and bushes can cause excessive movement, knocking, uneven wear and poor stability. We inspect undercarriage and linkage components, then replace worn parts onsite where suitable or at our Brendale workshop.
