Volvo G976 Motor Grader Repair Service Pdf Manual

Repair & Service Manual with Wiring Diagrams Overview

The Volvo G976 Motor Grader PDF Repair & Service Manual is the definitive technical authority designed for the professional maintenance and mechanical overhaul of this heavy-duty All-Wheel Drive (AWD) grader. Covering all applicable serial number ranges, this manual provides the specific factory procedures required to maintain the complex 6x6 hydrostatic drive system, the 11-speed transmission, and the precise circle turn mechanism of the G976 series.

The Volvo G976 is the flagship of the G900 family, distinguished by its powerful All-Wheel Drive System. It features hydraulically driven front wheels that provide exceptional traction for snow plowing and heavy drift control. Powered by a high-torque Volvo 6-Cylinder Turbo Diesel Engine, it utilizes the intelligent Volvo HTE Transmission with Autoshift technology. Maintaining the AWD hydraulic pumps, the front wheel motors, and the load-sensing hydraulic system is critical for ensuring the machine retains its pushing power. This service manual is the essential reference for technicians diagnosing AWD traction faults, calibrating the moldboard lift cylinders, and troubleshooting electrical control units.
