This Bomag BW 161, BW 202, BW 164 Service Training PDF pulls the hydrostatic drivetrain of five tandem vibratory roller variants apart on paper: 176 pages under OEM ID 008 098 47, spanning the AD, AC, and ADH-2 designations. Wiring diagrams map the supply and starting circuits down to individual component codes, while hydraulic schematics for the BW 161 AD and BW 202 ADH-2 trace pressure lines from travel pump to drum drive motor. When a roller creeps with the travel lever in neutral or vibration drops out at one drum, troubleshooting trees walk you from symptom to test port. Set charge pressure to 22 bar and verify the pressure override responds at 410 bar before you condemn a pump. Guess wrong on that call and you eat a rebuild the machine never needed. Bookmarks drop you from symptom chart to schematic in seconds, and the text layer speeds up spec lookups.
