以4缸机为例,利用本机型旧曲轴箱,先把最前和最后2道旧主轴瓦放在瓦胎上,再把曲轴抬上去,然后用百分表触头抵在第三道主轴颈上,慢慢转动曲轴,即可测得曲轴的弯曲方向及弯曲度。用粉笔标出弯曲方向后,在第三道主轴颈上部垫上一条用报废瓦片做成的60毫米长、20毫米宽的长型垫片,再把第三道主轴瓦下 To 4-cylinder machine, for example, the use of this model of the old crankcase, the first and last two old main bearing tile on the tile, and then lift the crankshaft, and then use the dial indicator contact arrived in the third spindle Neck, slowly turn the crankshaft, you can measure the crankshaft bending direction and curvature. After marking the direction of the bend with chalk, a 60 mm long, 20 mm wide washer made of scrapped tiles was placed on the upper part of the third main journal, and then the third spindle bush
