Preventative Repairs and Services

Regularly Scheduled Maintenance

At OTR Fleet Service, we understand the importance of regular maintenance in ensuring the optimal performance of your equipment and trucks. Our expert team provides routine oil changes and lubrication services using high-quality oils and lubricants specifically designed for diesel engines. By reducing friction and extending the lifespan of your engine, we help you maximize efficiency and productivity. We also conduct comprehensive fluid checks, including coolant and transmission fluid, to ensure they are at the recommended levels.

Visual Inspections

As part of our preventive maintenance services, we conduct thorough visual inspections of critical systems and components such as alignment, exhaust, suspension, and tires. By identifying any signs of wear and tear early on, we can address them promptly, minimizing the risk of breakdowns and ensuring the safety and reliability of your fleet. 

Advanced Monitoring

Equipped with advanced diagnostic tools, our skilled technicians at OTR Fleet Service monitor critical engine parameters to detect potential issues before they become major problems. Through continuous monitoring of exhaust gas temperatures, fuel injection pressure, and turbocharger performance, we gather essential data to make informed decisions. This data-driven approach allows us to implement necessary repairs and adjustments, preventing costly breakdowns.

Air Filter Services

Maintaining optimal engine performance and fuel efficiency is crucial for your fleet's success. OTR Fleet Service offers regular air filter replacements and cleaning services to ensure the smooth airflow necessary for peak engine performance. Our high-quality air filter services protect your engine from harmful contaminants, enhancing its longevity and reliability.

Fuel Filter Services

By keeping your fuel system clean and efficient, we prevent issues arising from poor fuel flow and reduce the risk of decreased engine performance. Our preventive maintenance services include fuel filter replacements to guarantee smooth fuel flow and maximize engine performance. We also offer specialized services for EGR (Exhaust Gas Recirculation) and DPF (Diesel Particulate Filter) to ensure optimal performance and compliance with emission regulations.
