Every fleet manager knows the importance of preventive maintenance (PM) for the health of its assets. By implementing a well-designed maintenance program, fleets can improve safety, reduce equipment downtime, increase productivity, and improve regulatory compliance. To achieve this goal the program needs to include regular inspections and maintenance checks on critical components such as tires, engine, aftertreatment, transmission, braking, hydraulic, tanks, and cooling systems.
A good PM program begins by following the manufacturer's recommended maintenance schedule. Work with your OEM’s and discuss the recommended service intervals on your equipment. In addition, stay current on any recalls or safety bulletins to ensure your equipment remains
Regular inspections of equipment should include identifying and addressing wear and tear; finding loose and missing parts; looking for and signs of corrosion — which if caught can reduce the risk of more extensive and costly repairs.
Your oil drain intervals will change based on your application. And if your fleet is running higher MPGs, there is a direct correlation to extended oil drain intervals. OEMs will also inform you of any changes in aftertreatment mileage changes, or even maintenance interval tracking through onboard diagnostics.
Failure to perform regular oil changes can result in excessive wear on engine components, leading to premature engine failure. Use oil analysis to adjust your drains based on your application. Dirty air filters can reduce engine performance, causing reduced fuel efficiency and increased emissions.
Failure to replace worn or damaged trailer brake components can cause increased stopping distances that increase the likelihood of accidents. Trailer payload will determine the wear and tear on tires and suspension components — the heavier the load the more likely it is that your tires and suspension will wear at a higher rate.
Failure to regularly inspect and maintain hydraulic systems will lead to costly roadside repairs and decreased efficiency. Worn or damaged suspension components can cause increased vehicle sway, reducing stability and potentially cause an accident.
