Volvo G946B Motor Grader Repair Service Pdf Manual

Repair & Service Manual with Wiring Diagrams Overview

The Volvo G946B Motor Grader PDF Repair & Service Manual is the definitive technical authority designed for the professional maintenance and mechanical overhaul of this All-Wheel Drive (AWD) grading machine. Covering all applicable serial number ranges, this manual provides the specific factory procedures required to maintain the complex AWD hydrostatic system, the heavy-duty circle drive, and the precise moldboard hydraulics of the G946B series.

The Volvo G946B is a premium grader distinguished by its All-Wheel Drive System, which provides superior traction in poor ground conditions. Powered by a high-torque Volvo Turbo Diesel Engine with Variable Horsepower (VHP) technology, it utilizes the smooth-shifting Volvo HTE Transmission. Maintaining the AWD hydraulic pumps and wheel motors, the load-sensing hydraulic valves, and the electronic machine monitoring system is critical for achieving final grade accuracy. This service manual is the essential reference for technicians diagnosing AWD system faults, adjusting the circle wear shoes, and troubleshooting electrical sensors.

Machine & Powertrain Information

The Volvo G946B is powered by a reliable Volvo 6-Cylinder Diesel Engine featuring V-ACT technology for optimal fuel efficiency and emissions compliance. This manual covers the specific maintenance requirements for this industrial power plant, including fuel injection diagnostics, turbocharger inspection, cylinder head overhaul, and cooling system service.

The machine utilizes a fully sequential Direct Drive Powershift Transmission (often 8 or 11 speeds) paired with the AWD system. Our manual guides you through the service of the transmission clutch packs, the front wheel drive motors, and the rear tandem drive axles.
