How Often Should a PM Be Done on a Semi Truck?

Routine maintenance is an important part of extending the life of a semi truck. In order to ensure that it runs properly, it should be inspected and serviced regularly.

Preventative maintenance (PM) is an effective way to keep a semi truck in good working order and to maintain its performance. But exactly how often should a PM be done on a semi truck?

The frequency of PM depends on several factors, such as the type of vehicle you have and the amount of use it gets. Generally, if you are using your semi-truck for business purposes, such as for hauling goods, you should have a PM performed every three months or 3,000 miles (whichever comes first). This will help ensure that any minor issues are caught and addressed before they become major problems.

For personal use vehicles, like those used for recreational activities like RVing or camping, the recommended interval for PM service is every six months or 6,000 miles (whichever comes first). This allows time between services to uncover any problems that may have occurred since your last PM.

When it comes to performing PM on your semi-truck, there are certain basic maintenance tasks that must be done each time. These include inspecting the brakes and hoses for wear or damage; checking all fluids including engine oil, coolant, brake fluid, and transmission fluid; replacing the fuel filter; inspecting belts; inspecting tires; and checking the battery.

Additionally, there are other services that should be done depending on your vehicle’s needs. For example, if your semi-truck has an air suspension system then you may need to have its airbags checked.

If you’re using your truck in extreme temperatures then an engine flush may be necessary. And if you’re using synthetic oil then you may need to change it more frequently than with regular motor oil.

In addition to having regular PM services performed on your semi-truck, it’s important to keep up with routine inspections and repairs as needed. This includes checking items like brakes and hoses for wear or damage as well as ensuring all fluids levels remain at proper levels.

Overall, how often a PM should be done on a semi-truck depends largely on usage but generally should occur every three months or 3,000 miles (whichever comes first) for business use vehicles or every six months or 6,000 miles (whichever comes first) for personal use vehicles. Additionally routine inspections and repairs should also be conducted when necessary in order to ensure optimal performance of your semi-truck.Conclusion

In conclusion regular preventative maintenance is essential in order to maintain optimal performance of a semi truck.

For business use vehicles this should occur every three months or 3 000 miles while personal use vehicles require servicing every six months or 6 000 miles (whichever occurs first). In addition routine inspections and repairs must also be conducted when needed in order to keep your semi truck running smoothly for years to come.
