Charge pressure, exciter settings, steering play: 231 pages of factory adjustment values separate a Serie 4 tandem roller from guesswork, and this Bomag BW 141, BW 151 and BW 154 service training PDF (OEM 008 097 16) puts them in your hands. Hydraulic schematics trace the closed-loop travel pump, vibration circuit, steering pump and crab-walk valve; the electrical half is bigger still, module descriptions on pages 147-198 ahead of the wiring diagrams on pages 199-228 that run from the supply and starting unit to the sprinkler module and working lights. Troubleshooting tables for travel, vibration and steering end each fault at a test port and a number. Set the Deutz inlet valve clearance to 0,3 mm cold, then confirm 26 bar at the brake pressure test port before the roller rejoins the pass. Guessing at a relief valve setting costs a travel pump and a second teardown. These pages print clean; let the bench copy get greasy while the bookmarked original stays on your laptop.
