Read the chapter summary below:

■ A proper maintenance program involves the inspection and servicing of the vehicle as a whole. The program's success depends on careful planning, often using predictive maintenance software.

■ CBM (Condition Based Maintenance) is reducing the amount of time spent on PM (Preventive Maintenance) in the modern truck shop. The objective is to achieve an AME (Automated Maintenance Environment) in which maintenance technology becomes more of an exact science.

■ A good maintenance program should bench-mark OEM (Original Equipment Manufacturer) standards tailored to the requirements of each individual operation.

■ The driver is always a key identifier of maintenance shortfalls when performing pre-trip and post-trip inspections.

■ The term out-of-service (OOS) when used in-house by a fleet defines minimum acceptable maintenance standards.

■ The term out-of-service (OOS) when used by the CVSA (Commercial Vehicle Safety Alliance) is not a maintenance standard. CVSA OOS criteria define legal minimum safety standards. Falling short of these standards can result in a citation.

■ A vehicle considered likely to cause an accident or breakdown because of mechanical conditions or improper loading should be written up by the technician or driver as OOS.

■ It is the fleet's responsibility to ensure that all personnel performing annual inspections are qualified.

■ Maintenance managers and truck technicians are expected to be computer literate because most service tracking is computerized.

■ Proper lubrication is important in reducing wear and preventing premature failure of truck components.

■ Winterizing a heavy-duty truck is an important part of any PM (Preventive Maintenance) program.

■ Performing a lube job properly is a requirement of an entry-level truck technician from day 1 on the job.
