Covering all applicable serial number ranges, this manual provides the specific factory procedures required to maintain the heavy-duty 6x6 drivetrain, the fully automatic planetary transmission, and the robust 3-point bogie suspension system of the A25C series.

The Volvo A25C is known for its incredible off-road mobility and simple, durable design.

This service manual is the essential reference for technicians diagnosing transmission shifting issues, rebuilding brake calipers, and troubleshooting electrical charging circuits.
