Strengths (What it does well)

1. Comprehensive Safety Section

• The manual begins with a detailed safety chapter (Bomag’s "Safety Instructions for Operating and Maintenance"). This is critical for the BMP 851 due to its high centrifugal force and pinch points on the exciter assembly.

2. Detailed Hydraulic Flow Diagrams

• For a small compactor, the BMP 851 has a complex hydrostatic drive system. The hydraulic schematics are accurate and include pressure check points for the propel pump and vibratory motor.

• The section covering the eccentric weight assembly (exciter) is excellent. It clearly shows the bearing preload procedure and the alignment marks for the eccentric weights (crucial for preventing vibration cancellation).

• All critical fasteners (wheel lugs, engine mounts, hydraulic fitting caps) are listed with NM and ft-lb values. The specification for the exciter bearing retainer nut is particularly valuable.

5. Parts Interchangeability

• The manual includes a clear breakdown of serial number breaks (e.g., "BMP 851 S/N 101 222 15 001 – 101 222 15 999"). This prevents ordering the wrong hydraulic pump or drum seal.
