Preventive service interval extension on Caterpillar 789 and 793 off-highway trucks

Objective: The project aims to develop and implement contamination control measures to extend the service intervals of Caterpillar 789 and 793 trucks. This will reduce operating costs by extending oil change intervals, maintaining oil quality throughout the lifespan of components and systems. Methodology: The feasibility of Caterpillar's "Committed to Customer Success" program was analyzed in collaboration with TRACSA. The project included simulating results to evaluate the impact of extending service intervals on reducing lubricant consumption, establishing machinery affinities, purchase volumes, suppliers, and maintenance schedules according to the manufacturer's recommendations. Results: The simulation showed significant savings in lubricant use, achieving a 50% cost reduction. Other benefits included prolonging the lifespan of components, better cleaning conditions, reduced handling of used oil, reduced carbon footprint, increased machine availability, and reduced downtime, improving work efficiency and safety.
