Four Bomag tandem vibratory rollers share this book: the BW 100 AD-3, BW 120 AD-3, BW 100 AC-3 and BW 120 AC-3, all four with the Deutz F2L 1011 engine. It runs 176 pages as an English PDF download, written for the mechanic doing the work rather than the operator.
The core of the book is hydraulic: pressure tests for the travel, vibration and steering circuits, flushing and bleeding procedures, and full disassembly and assembly of the travel pump, travel motor, drum with its vibrator shaft, and the oscillating articulated joint. Troubleshooting charts cover engine, electrical and hydraulic faults. Guessing a relief valve setting or a bearing end float on a machine like this ruins components fast; this manual gives you the factory figures. Bought once, it is yours to keep for the life of the roller.
Complete the set for your BW 100–120 AD/AC-3 Series
