Digger & Excavator Repair, Maintenance & Diagnostics Services

If the diggers aren’t digging, your site isn’t earning. As the absolute backbone of almost every UK construction, civils, and agricultural project, a broken-down excavator can cause an immediate, costly bottleneck.

Whether you operate a 1.5-tonne mini digger on a residential landscaping job or a 30-tonne 360 tracked excavator on a major infrastructure development, unexpected downtime is something you cannot afford.

Our team of mobile plant engineers are fully equipped to diagnose, service, and repair all makes and models of excavators right on-site or within our dedicated workshop. We get your machinery back tracking, swinging, and digging without delay.

Our Comprehensive Digger Services

1. Advanced Fault Diagnostics & Troubleshooting

Modern diggers rely heavily on complex electronic controls and high-pressure hydraulic systems. Our engineers carry advanced diagnostic computers to plug directly into your machine, pulling fault codes and bypassing the guesswork.

AdBlue & Engine ECU Diagnostics:

Resolving limp mode, regeneration failures, and emissions errors.

Hydraulic Pressure Testing:

Diagnosing weak pulling power, slow cycle times, or jerky boom and bucket movements.

Proportional Control & Joystick Troubleshooting

Fixing electrical signals between your cab controls and the main valve block.

2. Routine Maintenance & Servicing Programmes

Preventative maintenance is the secret to avoiding catastrophic component failure. We tailor our servicing schedules around your operational hours to keep your machine operating under peak conditions.

Slew Ring & Bearing Inspections:

Checking for play, greasing issues, or gear wear in the upper structure rotation.

Undercarriage & Track Maintenance:

 Adjusting tension, inspecting rollers, idlers, and sprockets on tracked diggers.

Full Filter & Fluid Changes:

High-grade oil, hydraulic fluid, and fuel filter replacements to protect sensitive fuel systems.
