Maintenance Schedule of Volvo Penta Power Generation Engine

Oct. 15, 2019

As we know that regular maintenance of engine is necessary and important. In this article, we mainly introduce the maintenance schedule of Volvo Penta power generation TD/TAD series engine.


Extended service intervals

The interval between engine oil changes may be extended in certain circumstances. To determine whether the service interval may be extended, Volvo Penta's conditions for extended service intervals must be met and an oil analysis performed. Contact your Volvo Penta dealer for further information.

Where both operational and calendar times are specified, perform the maintenance item at whichever time is the sooner.


Special Interval Service S1 - Every 125-500 Hours / at Least Every 12 Months(1)(2)

Special Interval Service S2 - Oil analysis.

Special Interval Service S3 - After the first 500 hours.

Type A service - Every 500 hours of operation.

Type B service - Every 1000 hours of operation.

Type C service - Every 1500 hours of operation.

Type D service - Every 2000 hours of operation.

Type E service - Every 8000 hours of operation

1) Oil change intervals vary, depending on oil grade and sulfur content of the fuel. Please refer to Oil recommendations.

2) Change oil filters every time the oil is changed.
