Volvo A25E Articulated Hauler/Dump Truck Repair Service Pdf Manual

Repair & Service Manual with Wiring Diagrams Overview

The Volvo A25E Articulated Hauler PDF Repair & Service Manual is the definitive technical authority designed for the professional maintenance and mechanical overhaul of this industry-leading 25-ton 6x6 truck. Covering all applicable serial number ranges, this manual provides the specific factory procedures required to maintain the intelligent Automatic Traction Control (ATC) system, the heavy-duty drivetrain, and the high-speed hydraulic dumping system of the A25E series.

The Volvo A25E is engineered for speed and efficiency in difficult terrain, featuring the revolutionary Automatic Traction Control (ATC) system that eliminates the need for manual differential lock engagement by the operator. Powered by a high-torque Volvo Turbo Diesel Engine, it utilizes a smooth Planetary Transmission to deliver optimal power to all six wheels. Maintaining the load-sensing hydraulic pumps, the exhaust retarder brake, and the electronic machine management system is critical for maximizing uptime. This service manual is the essential reference for technicians diagnosing transmission shifting faults, resealing hoist cylinders, and troubleshooting electrical sensors.

Machine & Powertrain Information

The Volvo A25E is powered by a fuel-efficient Volvo 6-Cylinder Turbocharged Diesel Engine utilizing Advanced Combustion Technology (V-ACT) to meet Tier 3 / Stage IIIA emissions standards. This manual covers the specific maintenance requirements for this industrial power plant, including the electronic unit injectors, the turbocharger, the internal exhaust gas recirculation (I-EGR), and the cooling system.

The machine features a Volvo PowerTronic Planetary Transmission with a lock-up torque converter and an integrated hydraulic retarder. Our manual guides you through the service of the transmission control valves, the transfer gearbox (drop box), and the heavy-duty drive axles equipped with dog-clutch differential locks.
