Bomag BW 145 DH-3, BW 145 PDH-3 Common Problems This Manual Covers
Bomag BW 145 DH-3 engine overheat warning buzzer sounds during heavy compaction passes.
Inspect the radiator fins for packed dirt and clear any debris. Drain the cooling system and refill with fresh coolant to the 15 L capacity noted on page 18. Verify the V-belt is tight and the water pump circulates fluid properly before putting the roller back on the mat.
Manual Section: Tests and Adjustments p. 18Hydraulic oil filter warning lamp stays illuminated after the machine reaches operating temperature.
Check the charge pressure at the travel pump test port. If the gauge reads below the 25 bar specification shown on page 17, replace the soiled hydraulic filter immediately. Drain and refill the hydraulic tank with 44 L of fresh fluid if the oil shows signs of severe contamination.
Manual Section: Tests and Adjustments p. 17Drum vibration fails to engage or frequency drops significantly below the normal operating range.
Review the fault charts starting on page 65 for vibration loss and check the nominal vibration frequency with a tachometer against the Tests and Adjustments specification. If the speed reads low, test the high pressure relief valve setting and adjust it to 405 bar if necessary.
Manual Section: Troubleshooting Diagram p. 65Low engine oil pressure warning buzzer sounds continuously immediately after a cold engine startup.
Verify the crankcase fluid level and add oil to meet the 10.5 L capacity. Check the wiring to the pressure switch. Keep in mind the engine oil pressure monitoring system delay is 4 seconds as detailed on page 548, so a brief alarm at startup might just be sensor lag.
Manual Section: Service Training p. 548Frequently Asked Questions
What is the correct valve clearance for the Deutz BF4L 2011 engine on a Bomag BW 145 DH-3?
On a cold engine (engine oil temperature <80°C/176°F), the intake valve clearance is 0.3 mm and the exhaust valve clearance is 0.5 mm. If the cylinder head gasket has been replaced, the clearances are 0.4 mm for the intake and 0.6 mm for the exhaust. p. 469
What is the procedure for bleeding the travel circuit on a BW 145 DH-3?
Bleeding involves installing pressure test hoses to the charge and high-pressure test ports, cranking the engine for 30 seconds with the starter, and repeating until oil runs out. Then, run the engine at idle for 15 seconds, wait 30 seconds, and repeat until the charge pressure gauge shows a constant pressure of 28 bar (406.1 psi). p. 51
What is the nominal charge pressure for the travel pump on a BW 145 DH-3?
The nominal charge pressure for the travel pump on the BW 145 DH-3 is 25 +/- 5 bar. p. 456
What torque for the flanged cover screws on the oscillating articulated joint of a Bomag BW 145 DH-3, BW 145 PDH-3?
The fastening screws for the flanged cover on the oscillating articulated joint must be tightened to 300 Nm (221.2 lbf*ft). p. 139
What exactly do I receive with this Bomag BW 145 DH-3 Repair Manual?
You download the Repair Manual yourself: 554 pages, searchable PDF, available immediately. Keep a copy on every device you use.
Are there any print restrictions on this Bomag BW 145 DH-3 manual?
Print away. There is no DRM and no page limit. Many buyers print one chapter at a time and leave the rest on a tablet.
Does this Bomag BW 145 DH-3 manual include hydraulic schematics?
Yes, hydraulic coverage is complete: system schematics, flow paths, valve configurations, and pressure ratings. You can see one on page 42.
