3) Aligning center The center alignment of engine and Generator is the most important factor for the extension of life cycle. z Output shaft flange and opponent side flange of Generator should be aligned in their centers horizontal and parallel direction. z The adjustment between flange surfaces at the lower part should maintain less than 0.15 mm when the upper part’s surfaces just meet and the deviation around the circumference should be maintained within 0.1 mm as following figure. Less than 0.1 mm Less than 0.15 mm EA3O3001I For bed rail is apt to deform for 6 months after initial performance, adjusting the center should be checked after 1 ~ 2 months. 5.5.3.
Installing fuel system Oil purifier should be installed between fuel tank and engine. For tank is always surrounded with humidity, water part often Infiltrates into fuel and then engine to result in the nozzle stuck and engine efficiency drop etc. z Example of fuel system installation Bed installation (Bubble generation) Bed installation (Bubble generation) Bleeding air Bed installation (Bubble generation) 5 ~ 100 mm Discharging Filter Feed pump Filter EFM8002I The position of fuel tank should be high than the engine fuel pump but when it is compelled to install at lower position, its lift should be within 1 m, and the fuel pipe be straight in order to prevent air bubble generation.
Maintenance of Major Components - 142 - Surface (TIR) Less than 0.15 mm Center (TIR) Less than 0.1 mm
