The Bomag 05722889 Flywheel is a genuine OEM flywheel designed for the BMP 851 trench compactor. Sourced directly from Bomag, this flywheel matches the original component specification, ensuring it seats and engages exactly as the factory intended for the BMP 851. When an aging or damaged flywheel is holding your compactor back, replacing it with the correct OEM part restores full engine power delivery and smooth operation.
Key Features
- Genuine OEM Mass and Balance — manufactured to Bomag's original rotational mass and balance specification, maintaining consistent engine inertia through every compaction cycle
- Direct-Fit Replacement — engineered to the same mounting pattern and dimensions as the original, so this flywheel drops into the BMP 851 without adapting or reworking the engine assembly
- BMP 851 Trench Compactor Compatibility — verified fitment for the BMP 851, so you can order with confidence knowing this is the correct part for your machine
- Restored Engine Smoothness — a correctly spec'd flywheel stabilizes crankshaft rotation and dampens power pulses, preventing the rough running and vibration that a worn or cracked flywheel causes
- Authentic Bomag Quality — as a genuine OEM component, part number 05722889 meets the same material and heat-treatment standards as the part that left the factory, supporting long service life under heavy compaction loads
The flywheel is a heavy rotating disc bolted to the crankshaft that stores rotational energy between power strokes, keeping the engine spinning smoothly and consistently. In a trench compactor like the BMP 851, where the engine drives continuous vibratory compaction forces, a properly functioning flywheel is essential for stable power output and controlled operation. When a flywheel cracks, becomes unbalanced, or its ring gear wears, the result is rough idling, hard starting, vibration, and accelerated wear on surrounding drivetrain components.
