System Coverage and Maintenance Documentation

Inside this BOMAG service training documentation, you get the exact technical baseline for the Kubota D 1703 MDI diesel engine, hydrostatic travel systems, vibration drives, and articulated steering components. It breaks down professional adjustment, troubleshooting, and maintenance protocols. Road construction equipment requires precision. This reference helps you hit those factory marks.

Technical modules map out the travel lever functions, including seat contact logic and automatic vibration control options. You also get a clear look at the wiring. The electrical section details system structures, cross-references, and pin assignments for all installed control and monitoring units.

Specification Preview

Performance and baseline data are fully documented to keep your equipment running smoothly. The travel pump charge pressure sits at 24 bar for standard operation. Because the main hydraulic travel circuit hits high-pressure relief settings of 380 bar, proper safety precautions and depressurization procedures outlined in the guide are critical before servicing.

Steering system pressure registers at 140 bar plus charge pressure. For engine work, intake and exhaust valve clearances on the Kubota power plant need a 0.20 mm calibration under cold conditions. Vibration circuit testing requires starting pressures around 210 bar.
