Bomag BM 1000/30 Common Problems This Manual Covers
Bomag BM 1000/30 cold milling machine starter turns over too slowly or only clicks when turning the key.
Test the magnetic switch for continuity. Limit your starter operation time to 1 minute as noted on page 23, then allow a 30-minute cooling time. Inspect the battery disconnect switch and verify all heavy cable ground connections are tight and free of corrosion.
Manual Section: Trouble shooting 'Starter' p. 23Travel pump making unusual whining noises and the machine has no volumetric flow or insufficient hydraulic power.
Drain the hydraulic tank and verify the system holds its full hydraulic oil capacity of 125 l as detailed on page 20. Inspect all suction lines to the axial piston pump for air leaks. Change the main filter if past the 500 operating hours replacement interval on page 19.
Manual Section: Trouble shooting axial piston pumps p. 20Milling drum stalls in the cut and fails to reach its rated speed under heavy asphalt loads.
Check the milling drive circuit and verify the milling drum rated speed hits 111 min-1 at full throttle, referencing page 41. Drain the planetary reduction drive and refill it with exactly 12 l of milling gear oil, checking the level plugs as outlined on page 20.
Manual Section: Assembly Groups p. 41Travel gear housing leaks fluid and wheel lug nuts constantly loosen during extended road milling passes.
Torque all M18 x 1.5 wheel nuts to the specified 300 - 350 Nm as directed on page 35. Inspect the travel gear hub seals for fresh oil leaks. Drain the final drives and refill with exactly 1.3 l of travel gear oil per side according to page 20.
Manual Section: General p. 35Frequently Asked Questions
How do I troubleshoot insufficient hydraulic power in the travel circuit?
To troubleshoot insufficient hydraulic power, first check the charge pressure, as it must be within the nominal range to build high pressure. Connect pressure gauges for high pressure and charge pressure, then disconnect the hydraulic motors and close the ports with pressure-resistant plugs to test the variable displacement pump. If the pump shows correct values, the fault lies in the hydraulic motors. p. 131
What are the torque specs for M12 screws with strength class 8.8 on the Bomag BM 1000/30?
The tightening torque for an M12 screw with a strength class of 8.8 is 88 Nm, assuming a coefficient of friction of 0.14. p. 33
How do I read diagnostic fault codes on the display?
To view fault codes, press any function key to open the menu bar, then press function key [F5] to enter the 'Diagnostics' menu. Active fault codes will be displayed with the SPN (Suspect Parameter Number), FMI (Failure Mode Identifier), and OC (Occurrence Count). p. 152
What is the engine oil capacity of the Bomag BM 1000/30 cold milling machine?
The engine oil filling capacity is 18 liters (4.8 gal us). p. 20
What is the correct belt tension for the travel pump drive?
The belt tension for the travel pump drive should be between 58 and 61 Hz. p. 241
