XCMG GR2605 Motor Grader Service Manual

This is the English-language service manual for the XCMG GR2605 motor grader, a full-size machine rated at 194 kW (260 hp) with a standard operating weight of 19,000 kg. The document is structured to take a technician from system-level understanding through hands-on disassembly, adjustment, fault diagnosis, and scheduled maintenance. It covers every major assembly on the machine, from the hydraulic torque converter and powershift gearbox through to the blade, the working devices, the hydraulic and electrical systems, and the air conditioning system.

Across its 311 pages the XCMG GR2605 Service Manual gives a technician complete system-level coverage of the machine — powertrain architecture including the hydraulic torque converter and powershift transmission, full hydraulic circuit schematics, wiring and electrical system detail, and blade/working-device geometry. The Assembly and Disassembly section alone spans more than 50 named component groups, each with step-by-step procedures, so a workshop can confidently tackle everything from blade cylinder replacement to a full torque converter pull.

Key Technical Specifications

The GR2605 Service Manual documents the machine as equipped with a Cummins QSB6.7 engine producing 194 kW at 2200 RPM. The powertrain uses a hydraulic torque converter feeding a powershift gearbox with 6 forward speeds (5, 8, 11, 19, 26, 47 km/h) and 3 reverse speeds (5, 11, 26 km/h). The blade measures 3965 × 610 mm with a maximum lifting height of 480 mm, maximum scraping depth of 715 mm, a 360° angle of revolution, and a tilt angle of up to 90°. The machine’s minimum turning radius is 7.9 m and its maximum gradeability is ≥25%. Hydraulic system working pressure is 22 MPa; gear box pressure is 1.85–2.2 MPa; steering cylinder pressure is 16 MPa. Oil filling capacities: coolant 50 L, fuel tank 270 L, engine 24 L, gearbox 38 L, balance box 85 L each, drive axle 44 L, hydraulic system 190 L.

What This Manual Supports

The XCMG GR2605 Motor Grader Service Manual covers the full range of workshop tasks: gearbox hydraulic brake adjustment, rear axle teardown and reassembly, blade and working device calibration, hydraulic pressure testing and circuit diagnosis, electrical fault tracing, torque converter removal (including tooling specifications: Q0-1090, 2 × 1T*2m slings), and engine assembly removal. The fault diagnosis chapter provides systematic guidance for isolating root causes before committing to disassembly. Scheduled maintenance tables span eight service intervals from daily checks through 2000-hour major service. Delivery is instant — you receive a PDF download immediately after purchase, readable on any device and printable for workshop use.
