The Bomag BW 174 AP-4 AM service manual PDF, factory document 008 916 49, breaks the tandem vibratory roller down across 932 pages, from travel and vibration pumps through both AM and AP drum rebuilds and pivot steering. Full-machine schematics sit at the back: hydraulic and wiring diagrams reproduced wire by wire and line by line. Troubleshooting charts trace no-vibration, low exciter shaft speed, and creep with the travel lever in neutral back to the component at fault. Fill the hydraulic tank with 50 litres, torque the rotary speed sensor to 12 Nm, and run your pressure tests against real factory numbers. A cooling mat won't wait while you hunt one relief valve setting. Print the pages you need and let them get greasy on the bench; the bookmarked, text-searchable file downloads right after checkout.
