From the Deutz TCD 2012 common rail fuel system to the closed-loop travel pumps, this 994-page Bomag BW 190 AD-4, BW 202 AD-4, BW 203 AD-4 service manual pdf (OEM 008 914 68) walks the entire tandem vibratory roller end to end. Detailed hydraulic schematics map the flow through the vibration and steering circuits, while complete electrical diagrams trace the EMR3 engine control logic. Troubleshooting charts isolate pressure loss in the axial piston swash-plate pumps, backed by dedicated teardown procedures for the AD-drum and oscillating articulated joint. When reassembling the drive components, you will torque the starter mounting screws to exactly 60 Nm and verify the carbon brushes meet the 5 mm minimum length. Guessing charge pressures on a closed-loop hydrostatic circuit will destroy a pump before the mat even cools, so print out the bookmarked pages you need and take the real factory data straight to the bench.
