Built for the BC series sanitary landfill and earth compactors, this 690-page Bomag bc 772 rs-2, bc 772 rb-2, bc 672 rs-2, bc 772 eb-2 service manual pdf (OEM 008 917 65) equips your shop for heavy repairs. The documentation breaks down the closed-loop travel pump circuits and control valve blocks with detailed hydraulic schematics. You will also find extensive EMR3 fault code lists and full wiring diagrams to trace CAN-bus faults on the TCD 2015 V6 engine before a machine stalls on the working face. Verify component health using precise factory targets, such as the 3µm rating for the fuel pressure filter or the 0.50 to 1.00 V specification for the steering joystick at maximum right input. Guessing on an oscillating articulated joint rebuild costs too much downtime and ruins expensive bearings. Download this text-searchable file, print the exact pages your crew needs, and take them straight to the bench or the landfill cell.

Bomag BC 772 RS-2, BC 772 RB-2, BC 672 RS-2, BC 772 EB-2 Common Problems This Manual Covers
Bomag BC 772 RS-2 steering only works in one direction or steering response is completely dead
Inspect the joystick input voltage on page 132. Verify readings show 3.60 to 4.60 V in neutral and 6.70 to 8.60 V at max left. Check the control block output current on page 136 to ensure it delivers 0.3 to 1 A to the steering valve.
Manual Section: Electronic Control p. 132Working pump defect triggers travel pressure drop and machine stops moving completely mid-pass
Test the primary pressure relief valve maximum pump pressure. Adjust the spool setting to reach exactly 260 bar as shown on page 425. Measure the pre-tensioning valve pressure on page 427 and confirm it holds at 18 bar to keep the drive pump charged during the lift.
Manual Section: Hydraulics p. 425Wheel drive refuses to engage or final drive brake locks up during operation on the cell
Measure the test pressure for hydraulic brakes at the final drive port. Apply 60-80 bar to release the piston as detailed on page 611. Drain the hub and refill the gear lube oil volume with exactly 6.5 litres of CLP 220 before returning to the fill.
Manual Section: Suppliers Documentation p. 611Engine overheats rapidly under heavy load and coolant temperature gauge pegs in the red zone
Remove the thermostats and test them in a hot water bath. Verify the A-Bank thermostat start of opening temperature is 79°C as specified on page 326. Measure the thermostat stroke length to ensure a minimum of 8 mm on page 327 before refilling the 50 litres of coolant.
Manual Section: Engine p. 326Frequently Asked Questions
How do I delete all stored fault codes from the ESX control?
To delete all stored fault codes, ensure the engine is not running. Enter code number 710 using the display module, then switch the ignition off and on again. All stored faults will be deleted. p. 116
What is the tightening torque for the oil pressure sensor on Bomag BC 772 RS-2, BC 772 RB-2, BC 672 RS-2, BC 772 EB-2?

What is the correct valve clearance for the Bomag BC 772 RS-2, BC 772 RB-2, BC 672 RS-2, BC 772 EB-2 TCD 2015 engine?
For the TCD 2015 engine, the intake valve clearance is 0.25 mm and the exhaust valve clearance is 0.30 mm. p. 318
What is the engine oil change interval for the Bomag BC 772 RS-2, BC 772 RB-2, BC 672 RS-2, BC 772 EB-2?
The engine oil should be changed every 500 operating hours, or at least once per year if the operating hours are not reached. p. 60
Tightening torque for oscillating articulated joint screws on Bomag BC 772 RS-2, BC 772 RB-2, BC 672 RS-2, BC 772 EB-2?
For the oscillating articulated joint screws, torque to 463 Nm. p. 525
