A BW 211 D-3 that quits vibrating mid-lift rarely tells you which relief valve gave up; this 164-page Bomag BW 211 D-3 Service Training PDF (OEM 008 099 75) is the factory training book written to answer that question for the single drum roller. Wiring diagrams trace supply, starting, brake, vibration and speed-range circuits, and the hydraulic schematic maps the closed travel loop from pump to Poclain drum drive motor. Troubleshooting charts walk you from no vibration, or a machine that creeps in neutral, back to a test port and a hard number. Set charge pressure to 25 plus or minus 1 bar at high idle, and confirm the travel pump's high pressure limitation at 475 bar before you condemn a pump. Guess those figures and you cook a hydrostat. Bookmarked, with a working text layer, the PDF rides on whatever screen goes out to the machine with you.

Bomag BW 211 D-3 Common Problems This Manual Covers
Bomag BW 211 D-3 moves a few feet forward, stops, then creeps a few feet in reverse
Check charge pressure first: it must hold 25 +/- 1 bar at high idle per the adjustment values on page 8. If it collapses the moment the machine stalls, inspect the drive coupling between the engine and travel pump for sheared rubber elements, then work the travel circuit troubleshooting steps starting on page 69 before condemning the pump.
Manual Section: Travel System p. 69Roller will not drive in forward or reverse even though the engine runs at full speed
Verify charge pressure reaches 25 +/- 1 bar; without it the multi disc brakes never release and the machine sits dead. Then test high pressure in the travel loop: the relief valves are set at 475 bar per page 48. If neither side builds pressure, pull the pump and inspect the drive coupling before the next lift goes cold.
Manual Section: Travel System p. 48Steering extremely stiff, drum slow to respond, articulated joint will not reach end stops
Measure steering pressure while holding the wheel against an end stop; the relief valve is set at 175 bar per page 124, with maximum steering pressure at 210 bar. Low readings point to a worn steering pump or leaking steering valve. If pressure is good, inspect the articulated joint bearings in the steering section starting on page 123 for binding.
Manual Section: Steering System p. 124Vibration cuts out on high amplitude or drum barely shakes at full throttle
Test the vibration circuit against the values on page 112: starting pressure should spike to 365 +/- 35 bar, then settle near 90 +/- 15 bar on low amplitude or 110 +/- 15 bar on high. A loop that never spikes points to the high pressure relief valves; steady low readings mean a worn vibration pump or motor.
Manual Section: Vibration System p. 112Engine ticking loudly at the valve cover and losing power on grade
Adjust valve clearance with the engine cold: 0.3 mm inlet and 0.5 mm outlet per the technical data on page 8. Torque the cylinder head cover to 9 +/- 1 Nm on reassembly per page 42. Do this at the intervals in the maintenance table on page 11 before chasing fuel system faults.
Manual Section: Deutz Diesel Engine p. 8Frequently Asked Questions
What are the tightening torque specifications for the cylinder head cover on the Deutz BF4M 2012C engine?
The tightening torque for the cylinder head cover on the Deutz BF4M 2012C engine is 9 +/- 1 Nm. If the gasket is damaged, it must be replaced during this maintenance procedure. p. 42
What is the correct valve clearance for the Deutz BF4M 2012C engine?
The valve clearance for the Deutz BF4M 2012C engine must be checked and adjusted when the engine is cold. The intake valve clearance is 0.3 mm and the exhaust valve clearance is 0.5 mm. p. 25
What is the filling capacity for the hydraulic oil system on the BW 211 D-3?
The hydraulic oil filling capacity for the BW 211 D-3 is 60 liters. The specified oil type is HVLP 46 VI 150. p. 9
What is the nominal charge pressure for the travel system on the BW 211 D-3?
The nominal charge pressure for the travel system is 25 +/- 1 bar, measured at high idle speed. p. 79
What is the procedure for manually releasing the brake on the Poclain drum drive motor?
To manually release the brake, remove plug 1, lay the U-bar (5) across the brake housing (2), and turn the screw (4) into the tapped bore (3) until it bottoms. Then, turn the nut (6) down and tighten it for approximately one turn until the drum turns freely. p. 62
