Utilize oil wear analysis at every major service interval to monitor engine oil, hydraulic fluid, and coolant health. Analyze wear metals like iron and copper, as well as contaminants such as silicon or sodium. Integrating KOMTRAX telematics allows for remote monitoring of fuel consumption, load frequency, and DEF levels, enabling proactive adjustments before component failure occurs.

Monitor the electrical system for fault codes; E10 or E15 codes may indicate engine controller power failure or sensor malfunctions. Regularly inspect hydraulic hoses and pins/bushings at attachment points to prevent leaks and play. For brake-related issues, perform function tests on the wet disc/retarder system and check for any abnormal resistance in the service or parking brakes.

At 2,000-hour milestones, execute a comprehensive component evaluation. Focus on the transmission service, including oil and filter replacement, and the hydraulic system overhaul involving a full oil change. For high-hour machines, inspect the turbocharger for wear and perform detailed measurements of structural welds and the articulation joint to plan for major frame or powertrain rebuilds.

In cold weather operations, prioritize checking the hydro-pneumatic suspension and ensuring all fluids are at correct viscosity. During high-dust summer months, increase frequency of air filter inspections and radiator/oil cooler cleaning to prevent overheating. Ensure the cooling system SCA levels are tested regularly to prevent corrosion in extreme temperature fluctuations.
