Whether you are pulling a travel motor on the fill or chasing an electrical fault on the landfill cell, this 886-page Bomag BC 473 RB-4, BC 473 RS-4, BC 473 EB-4 service manual PDF is the official factory reference for these refuse and soil compactors (OEM 008 400 22 EN). The documentation breaks down the closed-loop travel circuit with detailed hydraulic schematics and troubleshooting charts that map out hydraulic test and adjustment points. Your electrical diagnostics move faster through extensive wiring diagrams covering the SCR exhaust aftertreatment and engine electrics. You can verify the engine shut-down solenoid actuator relay requires a 24V/15A rating, and torque the main fuel filter screw-on cover to exactly 25 Nm. Guessing at a travel system failure usually means buying the wrong pump or ruining an expensive replacement component, so download this bookmarked, text-searchable document and get your machine back to making passes over the lift.
