ASSEMBLY The engine and alternator are close coupled by means of an SAE flange. A full torsion

analysis has been carried out to guarantee no harmful vibration will occur. Anti-vibration pads are used between the engine, alternator feet and the base frame. Thus

ensuring complete vibration isolation of the rotating assemblies and enabling the machine to be placed on an uneven surface without any detrimental effects.

For durability and corrosion resistance, all iron and steel surfaces have been treated by grit blast cleaning and coating. Then covered by special three layers painting which provides an excellent corrosion resistant surface.
