Bomag BMF 2500 M Common Problems This Manual Covers
Bomag BMF 2500 M conveyor belt edge damage and material flow interruption under high output
Inspect the belt guides and scrapers for severe wear. Remove damaged sections and install the replacement belt splice using a 500 g hammer as specified on page 381. Verify roller alignment to ensure the belt tracks straight before restarting the paving train.
Manual Section: Assembly Groups p. 381Engine runs rough, lacks power during heavy material transfer, and exhibits unburned fuel smoke
Test the injector electric resistance. Replace the injector if the reading falls outside the 3 Ohm specification found on page 275. Clean the seating surface, install a new 1.5 mm sealing ring from page 272, and torque the feed pipe union nut to 55 Nm.
Manual Section: Diesel Engine p. 275Abnormal grinding noise from the conveyor undercarriage area and dry drive chains during operation
Check the chain lubrication system controller. Verify the timer is set to the correct operating intervals of 3 minute operation, 11 minutes break as detailed on page 375. Fill the reservoir, prime the lines, and confirm oil reaches the roller pins to prevent mid-mat failures.
Manual Section: Assembly Groups p. 375Engine won't crank or turns over slowly when trying to start the machine in cold weather
Confirm the battery voltage and cable connections are solid, then remove the starter and inspect the ring gear. Install the new starter motor and tighten the main mounting screws to 43 Nm as shown on page 270, and secure the M10 fastening nut to 21 Nm to ensure proper ground.
Manual Section: Diesel Engine Troubleshooting p. 270Frequently Asked Questions
