Comprehensive Diesel Engine Services

Reid Diesel Services provides complete diesel engine maintenance and repair solutions for heavy equipment, trucks, and machinery operating in demanding conditions.

Engine Diagnostics & Fault Finding

Accurate diagnostics are essential for identifying issues early and preventing major failures. We use advanced diagnostic tooling and fault-finding processes to identify engine and component problems efficiently.

  • Engine diagnostics and scan tool analysis
  • Fault code detection and troubleshooting
  • Loss of power diagnosis
  • Excessive smoke diagnosis
  • Overheating investigations
  • Oil leaks detection
  • Cooling system fault diagnosis
  • Fuel system troubleshooting
  • Abnormal engine performance inspections

Diesel Engine Repairs & Rebuilds

We provide diesel engine repair and rebuild services for heavy machinery and equipment across a wide range of applications.

  • Complete diesel engine rebuilds
  • In-frame rebuilds
  • Top-end overhauls
  • Cylinder head repairs and replacements
  • Engine reseals
  • Pistons, liners, bearings, and gasket replacement
  • Loss of power, excessive smoke, and overheating diagnosis
  • Fuel injector servicing
  • Major engine component repairs

Where possible, we take a practical and cost-effective approach by assessing whether components can be repaired or rebuilt before recommending replacement.

This helps extend equipment life while reducing unnecessary repair costs.

Hydraulic & Driveline Repairs

Hydraulic and driveline failures can significantly impact machine performance and productivity. We provide repair and maintenance solutions for critical components to help keep equipment operating reliably.

  • Hydraulic pump repairs and replacement
  • Hydraulic cylinder repairs
  • Final drives repairs
  • Driveline repairs
  • Transmission servicing and repairs
  • Brake system repairs and adjustments

Preventative Maintenance & Fleet Servicing

Preventative maintenance plays a critical role in reducing unexpected breakdowns and extending machinery life.

Reid Diesel Services works with businesses across South East Queensland to provide scheduled servicing and fleet maintenance programs tailored to operating conditions and equipment requirements.

  • Scheduled diesel engine servicing
  • Oil and filter changes
  • Cooling system maintenance
  • Fuel system servicing and cleaning
  • Battery and charging system inspections
  • Fluid analysis and inspections
  • Early wear detection and reporting
  • Site maintenance support

Regular servicing helps identify wear and component issues before they become major failures, improving reliability and reducing long-term operating costs.

Undercarriage Repairs & Replacement

Undercarriage components are among the highest wear areas on earthmoving equipment. Excessive wear or failure can lead to costly downtime, reduced performance, and further mechanical damage if left unaddressed.

Reid Diesel Services provides complete undercarriage inspections, repairs, and replacement services for excavators and tracked machinery across South East Queensland.

  • Track chain replacement
  • Steel and rubber track replacement
  • Sprocket replacement
  • Carrier roller replacement
  • Bottom roller replacement
  • Idler repairs and replacement
  • Track tensioner and adjuster repairs
  • Undercarriage inspections and wear reporting

We take a proactive maintenance approach by identifying wear early and helping clients plan repairs and replacements before failures occur onsite.

Recent Project: Excavator Undercarriage Replacement

We recently completed a planned undercarriage replacement on a Volvo ECR235 excavator for a civil contractor in South East QLD.

By identifying wear early during a scheduled service, we helped the client plan ahead—replacing tracks, sprockets, and rollers during a planned downtime period. This avoided unexpected breakdowns and kept the project running smoothly.
