A BW 164 AD that loses travel drive or drops vibration mid-mat stops the whole paving train, and that failure is what this Bomag BW 164 AD repair manual PDF was written for: 232 pages of factory repair procedures for the tandem vibratory roller, OEM ID 008 193 12. Troubleshooting charts for the travel system, vibration and steering walk you from symptom through pressure tests to the component at fault, and a wiring diagram section maps the machine's electrical circuits. Repair coverage runs from exchanging the cylinder block and brake discs in the travel motor to pulling the drum, swapping rubber buffers and resealing the vibration motor drive shaft. Check diesel engine speed against the 2150 rpm factory figure; pull the mounting nuts to 420 Nm. Every hour that roller sits, the mat behind the paver goes cold. Bookmarked and carrying a real text layer, the PDF rides along on whatever screen is in your cab or service van.

Bomag BW 164 AD Common Problems This Manual Covers
Bomag BW 164 AD stops traveling after warm-up, drive brake will not release
Check the seat switch and brake solenoid wiring before pulling any pump. Measure solenoid current draw; nominal is 1.23 A on page 51. Verify charge pressure holds 18 to 22 bar (page 47); the brake needs at least 10 bar to release (page 17). Work the travel troubleshooting chart that starts on page 49.
Manual Section: Travel System Troubleshooting p. 49Machine does not travel in either direction even though the engine runs at full speed
Tee a gauge into the travel circuit and run the high pressure test on page 48; nominal value is 400 bar. If charge pressure sits below 18 bar, suspect the charge pump or an internal leak. Measure travel motor case leakage; more than 2 L/min at 200 bar (page 16) means the motor is worn out.
Manual Section: Travel System Pressure Tests p. 48No vibration on front or rear drum after switching on the exciter
Start at the vibration switch, wiring and control solenoid before condemning hydraulics; the solenoid should draw 1.23 A. Then gauge the circuit: starting pressure should hit 400 bar and settle to 80 to 120 bar operating, both on page 139. Low readings with warm oil point to a worn vibration pump or motor.
Manual Section: Vibration System Troubleshooting p. 138Vibration weak on one drum, exciter shaft speed too low at full throttle
Run the exciter shaft speed procedure on page 135; low frequency usually means hydraulic supply, not the shaft itself. Verify the engine reaches 2150 rpm at full throttle first. Then measure vibration motor case leakage: anything over 1 L/min at 100 bar (page 16) means the motor is worn and dragging frequency down.
Manual Section: Vibration System Speed Check p. 135Steering stiff and slow to respond, drum barely turns at full engine speed
Gauge the steering pressure and adjust it; nominal is 160 bar (page 16). The steering section starting on page 185 covers the test and cylinder repair. Verify hydraulic oil level first: the tank holds 60 L (page 17), and a low level starves the circuit. If pressure adjusts fine but steering stays stiff, inspect the articulated joint.
Manual Section: Steering p. 185Frequently Asked Questions
How do I check the torque specifications for bolts on the BOMAG BW 164 AD?
Torque specifications are provided in the torque table on page 18. For example, an M10 bolt with 8.8 grade requires 50 Nm (37 ft-lb), while an M10 bolt with 10.9 grade requires 75 Nm (55 ft-lb). p. 18
What is the procedure for checking the diesel engine speed?
Drive the machine onto an elastic base (rubber tyres), start the engine, and set the throttle to the maximum speed position. Use a frequency meter to check the speed; the nominal value is a minimum of 2150 rpm. p. 31
What is the required tightening torque for the rubber buffer nuts?
When installing the rubber buffers, the mounting nuts must be tightened to a torque of 420 Nm. p. 59
What is the nominal charge pressure for the travel system?
The nominal charge pressure for the travel system is between 18 and 22 bar, measured at operating temperature. p. 47
What is the correct V-belt tension for the steering/charge pump?
The V-belt is correctly tensioned if it cannot be compressed more than 10 to 15 mm between the V-belt pulleys. p. 194
