Troubleshooting takes the deepest cut of this 762-page book: emergency towing and the complete Deutz fault code list, and that is just one chapter of the Bomag BC 463 RB-3, 473 RB-3, 473 RS-3 and 473 EB-3 service manual PDF, OEM document 008 402 12 EN covering these refuse and fast moving soil compactors. Circuit diagram 382 traces the wiring through the central electrics and Deutsch DT connectors; hydraulic diagram 571 908 27 maps the closed-loop travel pump, fan circuit and working hydraulics. Repair chapters walk you through the oscillating articulated joint from teardown to reassembly. Set steering relief at 250 bar max. Torque M12 x 1.5 hydraulic fittings to 15 Nm. A compactor dead on the cell face for want of one fault code stalls the tipping schedule. Buy the bookmarked, text-indexed PDF once and it stays yours for the life of your machine.

Bomag BC 463 RB-3, BC 473 RB-3, BC 473 RS-3, BC 473 EB-3 Common Problems This Manual Covers
Bomag BC 473 engine won't crank, no starter response, intermittent start after machine sits overnight
Check the batteries first: the machine runs 12V / 100Ah batteries with a 28V / 100A generator, spec'd on page 162. Verify the main battery switch is closed and the 10A starter switch fuse is good. Then work the electrical troubleshooting procedures from page 497 and trace the start circuit on the wiring diagram.
Manual Section: Troubleshooting, electrical systems p. 497Dozer blade slow or won't lift, all hydraulic functions weak once the oil warms up
Test charge pressure before condemning the pump; the charge pressure relief valve is set at 30 bar, listed on page 598. Check the dozer blade circuit against its 250 bar maximum from page 86. If both read low, inspect suction lines and the return filter, then trace the circuit on the hydraulic schematic.
Manual Section: Trouble shooting, hydraulics p. 598Refuse and wire wrapping the wheels, scrapers no longer clearing material between the tips
Adjust scraper clearance: inner scrapers run at 0 mm against the wheel, all others at 5 to 10 mm (0.2 to 0.4 in), per page 419. Torque the scraper fastening screws to 502 Nm (370 ft·lbf) as given on page 417, set the edge cutters 1 to 2 mm off the wheels per page 420, and get back on the cell.
Manual Section: Machine Assemblies p. 419Engine temperature climbing on long pushes, coolant warning coming on after a few hours in the cell
Clean the cooling package before chasing anything else; landfill debris plugs the cores long before a thermostat dies. Blow the coolers out from the fan side, check fan drive operation, and inspect the pressure relief valve in the coolant circuit, set at 25 bar per page 84. Verify oil level against the 21.5 l engine capacity on page 95.
Manual Section: Machine Assemblies p. 323Fault lamp on with active Deutz fault codes, engine dropping into emergency mode mid-shift
Read the stored codes before swapping parts; the Deutz DTC fault code list sits in the diesel engine troubleshooting section, with the error code reference. Check charging first, since a weak battery mimics sensor faults: confirm output from the 28V / 100A generator listed on page 162. Clear the codes and retest under load before releasing the machine.
Manual Section: Trouble shooting, diesel engineFrequently Asked Questions
How do I reset a BOMAG BC 473 RB-3 fault code?
To delete all stored faults, ensure the engine is not running, enter code number 710 (without service code 9999), and then switch the ignition off and on again. For engine control fault logs, use service code 9999 and enter code number 0760 while the engine is not running, then cycle the ignition. p. 196
What are the torque specifications for BOMAG BC 463 RB-3 wheel nuts?
The tightening torque for wheel nuts (fine thread) on the BC 463 RB-3 depends on the thread diameter. For an M12 x 1.5 thread, the torque is 100 Nm; for M14 x 1.5 it is 150 Nm; for M18 x 1.5 it is 300-350 Nm; for M20 x 1.5 it is 400-500 Nm; and for M22 x 1.5 it is 500-600 Nm. p. 54
How do I read BOMAG BC 473 RS-3 error codes?
To query active faults of the engine control unit (for V1.xx displays since 2016), enter input code 750. The display will show the SPN (Suspect Parameter Number) as 'S 257'. Pressing the 'INFO 2' button will show the FMI (Failure Mode Identifier), and pressing it again will show the OC (Occurrence Count). p. 198
What is the engine oil capacity for the BOMAG BC 463 RB-3?
The engine oil filling quantity for the BC 463 RB-3 is 21.5 liters (10 gallons US). p. 95
What is the valve clearance specification for the Bomag BC 463 RB-3, BC 473 RB-3, BC 473 RS-3, BC 473 EB-3 engine?
The valve clearance for the intake valve is 75° ± 15° and for the exhaust valve is 105° ± 15°. p. 394
