32.发电机端盖凸耳的折断发动机在使用中,常要调整风扇皮带的张紧度。由于发电机皮带轮作为张紧轮,因此,在调整中需要移动发电机支架的左右位置,使发电机皮带轮和风扇皮带轮及曲轴皮带轮的齿槽为同一平面,然后拧紧发电机支架的紧固螺栓。而在这一调整过程中,如不小心,发电机端盖凸耳就会折断,因为发电机端盖为铸铁材料,结构上较单薄脆弱, 32 generator cover lugs break engine in use, often need to adjust the tension of the fan belt. Because the generator pulley acts as a tension pulley, it is necessary to move the left and right sides of the generator bracket so that the generator pulley and the fan pulley and the crankshaft pulley are flush with one another, and tighten the fastening bolts of the generator bracket. In this adjustment process, if not careful, the generator cover lugs will be broken, because the generator cover is cast iron material, the structure is relatively thin and weak,
