Car preventive maintenance checklist4/2/2024 ![]() The normal interval for “B” service is 3,000 to 5,000 for light-duty vehicles and 10,000 to 20,000 for medium- and heavyduty vehicles. PM Bs normally include all PM A items, and also include an oil and filter change as well as more in-depth checks of the engine and driveline. Note: Some companies use an “inspection lane” and perform an “A” service every time the vehicle returns to the maintenance facility. Typically, these PM As are scheduled at half of the oil change interval of the vehicle. The normal interval for “A” service is between 1,500 and 2,500 miles on light vehicles, and between 5,000 and 10,000 miles on medium- and heavy-duty vehicles. It also includes checking and adjusting high-wear components. PM A service is also known as a “maintenance check-out” or “safety inspection” and generally consists of a safety check and lubrication as well as checks of key components such as brakes, lights, tire condition and inflation, and fluids. As you move down the alphabet from A to B and so on, the PM service (and time required) increases in complexity. This is sometimes referred to as the vehicles’ “scheduled service,” or simply “service.” PM services are commonly designated as A, B, C, D, etc. ![]() The actual maintenance portion of PM is composed of scheduled and standardized inspections and maintenance. Note that the federal regulations require a “systematic” inspection, repair, and maintenance program, but they leave the details up to you. As PM takes hold, the standard of excellence for a maintenance shop changes from getting the fastest repairs to getting the fewest repairs. The PM philosophy is widely used, not only because it reflects a modern attitude of conservation - of using assets wisely - but because it saves money. This is much like preventive medicine that stresses good eating habits and regular exercise as a continuing prescription for good health and long life. It means getting the best, most cost-effective equipment for the truck and then taking care of it. It means being constantly on the lookout for things that might go wrong. Preventive maintenance is also an attitude, a commitment. This allows you to make repairs on your schedule, prevent violations and accidents, and keep the vehicles rolling. This type of maintenance program is destined to lead to down-time and the resulting costs of idle equipment.Ī preventive maintenance program, on the other hand, brings vehicles in for inspection and maintenance on a schedule, and repairs any items that are at, or even approaching, an established cut-off point. The problem with reactionary maintenance programs is that they are based on failure, i.e., you notice something has failed and you fix it. ![]() If vehicles are only brought into the shop when they need something, the program is not preventive, it is reactionary. Through preventive maintenance, vehicles are inspected, repaired, and maintained in such a way that defects are prevented from surfacing in the first place, before a violation or accident can occur. Preventive maintenance (PM) is the key to any successful maintenance program for commercial motor vehicles.
