Bomag BC 972 RB-2, BC 1172 RS-2 Common Problems This Manual Covers
Bomag BC 972 RB-2 hydraulic system overheating warning light flashing and travel pump whining
Inspect the hydraulic tank and verify it holds the full 600 L capacity listed on page 41. Replace the charge oil filter with a new 12 µm element. Test the differential pressure switch activation at 2.5 bar as shown on page 474.
Manual Section: Hydraulics p. 474Engine oil pressure sensor leaking oil down the block near the main harness connector
Remove the leaking sensor and clean the block threads. Install the new sensor and torque it to exactly 20 Nm. Check the cylinder head cover for secondary leaks and torque the bolts to 22 Nm.
Manual Section: Engine Electrics p. 334Machine lacks pushing power on the landfill cell and travel pump sounds like it is cavitating
Hook a test gauge to the control chamber pressure test port on page 478 and verify pressure reaches 475 bar at maximum displacement. If pressure fluctuates, check the pressure regulator fixed setting to ensure it holds steady at 250 bar.
Manual Section: Hydraulics p. 478Diesel engine bogs down under heavy load when climbing steep refuse grades
Drain the water separator and replace the main fuel pressure filter with a new 3µm element as detailed on page 379. Prime the system and run the engine to verify smooth operation. Check the 1000 L fuel tank for heavy contamination.
Manual Section: Engine p. 379Frequently Asked Questions
