Bomag's service manual 008 915 20 takes the BW 174 AP AM and ACP AM tandem vibratory rollers apart on paper before you ever pull a cover: 974 pages of factory repair procedures, tests and adjustments, and Asphalt Manager diagnostics. This Bomag BW 174 AP AM, BW 174 ACP AM service manual PDF closes with hydraulic diagrams 870 206 09 and 870 203 12 plus wiring diagram 870 100 25, and its troubleshooting charts trace no vibration, machine does not drive, and hydraulic oil overheating faults through the closed-loop travel circuit. Drum repair fills a long chapter, from pulling the AP drum to rebuilding the Vario exciter on the AM side. Tee a 60 bar gauge into the brake releasing line before condemning a travel pump, and torque M5 10.9 hardware to 9 Nm on reassembly. A roller that quits mid-mat parks the whole paving train. Bookmarked and text-searchable, the PDF gets your roller back in the pass.
