This maintenance program has been based on the progress in vehicle technology and increases in oil quality to simplify the maintenance.For simplified scheduling, the program has tied maintenance to logical time or mileage limits that make it easy to anticipate needed servicing. For the majority of onhighway operators, the 24,000 km (15,000 miles) or 4 months schedule can be used with little change.It is important that the scheduled intervals are followed as limits. Maintenance can be done before either 24,000 km (15,000 miles) have been reached or before 4 months are up but must be made at or before either the mileage or the time limit has been reached.
For further information concerning component specifications see service information in Group 1, “Oil and Filter Change Intervals for Volvo Components, All Models”, Publication Number 175–001, and any appropriate vendor literature.
Advantages
A well-planned preventive maintenance program offers the following advantages:
The lowest attainable maintenance cost.Maximum vehicle uptime.Better fuel economy.Reduced road failures; greater dependability.Increased customer confidence, better public relations.Less possibility of accidents due to defective equipment.
Fewer driver complaints.
Regardless of the planning and the details of the maintenance program, the success of the program hinges on the caliber of workmanship in performing the actual inspection. A major cause of failure is a “pencil inspection;” that is, the mechanic checks off each operation as being OK without making the actual inspection. A “pencil inspection” defeats the purpose of the inspection, which is to detect an impending failure.
