Bomag put its own part number on this book: 008 191 32, the 318-page factory repair manual for the BW 161 AD and 202 AD tandem vibratory rollers. Hydraulic schematics trace the closed-loop travel and vibration circuits, wiring diagrams map the relay board and monitoring module, and troubleshooting charts walk travel, vibration, and steering faults back to a testable cause. Sealing procedures take the travel and vibration pump apart valve by valve, so you can reseal a leaking control unit instead of replacing the whole pump, then flush the circuit afterward. Set charge pressure inside the 18 to 22 bar window, confirm 390 to 410 bar on the high pressure test, and torque the coupling screws to 90 Nm. A guessed relief pressure can cook a pump in one shift. Bookmarked and text-searchable, it rides on whatever screen you carry to the machine.
