Komatsu AFE48-BZ(930E-2 S/N A30186-A30188 CODELCO)

Implement Komatsu Oil Wear Analysis (KOWA) at every 500-hour interval to monitor engine oil, hydraulic fluid, and coolant. Analyze wear metals such as iron, copper, and lead in the engine oil to detect internal component degradation early. Check hydraulic fluid for particle count and water content to prevent pump and valve failure. Monitor coolant pH and SCA concentration to ensure corrosion protection for the Cummins QSK60 engine block and radiator. Track fuel dilution and soot levels to optimize engine oil change intervals based on actual operating conditions rather than fixed schedules.

Address frequent undercarriage wear by measuring track tension and shoe condition daily, as CODELCO operations demand high durability. Inspect hydraulic hoses for cracks and leaks during every 10-hour walk-around to prevent fluid loss and contamination. Check brake system pads and discs at 500-hour intervals for wear, replacing them before structural damage occurs. Monitor the air filter restriction indicator and clean or replace the outer element at 1,000 hours to maintain engine performance. Inspect the turbocharger for shaft play and oil leaks during the 1,000-hour service to prevent power loss and excessive smoke.

Plan major component overhauls based on cumulative hours and fluid analysis trends. Change final drive oil and inspect gears at 1,000 hours, with full overhaul typically required after significant mileage or oil contamination events. Replace transmission oil and filter at 2,000 hours, evaluating clutch packs and torque converter condition. Flush the cooling system and replace coolant at 2,000 hours to prevent scaling and blockage. Evaluate the swing machinery oil and bearings during the 1,000-hour check, replacing worn bearings before they damage the swing circle or drive gears.

Adjust maintenance for CODELCO's high-altitude and dusty environment. Clean radiator and oil cooler fins daily to prevent overheating in hot conditions. Use Komatsu Super Coolant AF-NAC to handle extreme temperature variations. In dusty conditions, inspect the air filter more frequently than the standard 1,000-hour interval, cleaning the pre-cleaner daily. Check battery terminals and alternator connections at 500 hours, as dust can cause corrosion and electrical faults. Inspect all grease points daily, using Komatsu grease to protect against abrasive dust ingress in suspension and steering pivots.
