If you run a Bomag BMP 851, you know you’re dealing with a specific kind of beast. It’s a trench roller, designed for the tight spots, the awkward angles, and the punishing work that lighter machines can’t handle. But even the best German engineering eventually bows to the laws of physics. Plates wear, solenoids stick, and hydraulic fluids degrade.
The exciter system is critical for compaction. The manual provides instructions on checking the vibration frequency and amplitude, as well as replacing bearings in the drums. 4. Radio Remote Control (RRC) System
Connect a 400-bar pressure gauge to the test ports located on the main control valve bank.
Regular service extends the machine's life and ensures "functional safety". Key tasks outlined in the manual include: Check engine oil, fuel, and hydraulic oil levels.
