Features

Noise Reduction

New block for low noise and vibrations, Insulated timing case cover, Isolated oil pan (also provides ease of maintenance), Improved pump and gear train system, Stiffer crankshaft, Multiple fuel injection strategy, 4 valve cross flow head, Double curvature on thick walled crankcase, Piston optimized for high speed operation

Hydraulic Tappets

Hydraulic tappet adjustment removes the need for manual tappet adjustment, that on the 1006 (C6.6) needed to happen every 500 hours. This system is operated by oil pressure, and this saves the customers a considerable amount of cost from an Operating perspective.

Improved Smoke Levels

Improved smoke levels from C4.4 mechanical engine

Serpentine belts to achieve longer service intervals

These belts are more efficient, as they provide more drive surface. Less heating is created during running, and the belt will also last longer. The poly V belt cannot twist over like a single V belt, and any wear of the poly V belt becomes apparent a long time before failure.
