在修理AK-10型起动机时,由于缺少曲柄总成装配专用工具,很难保证前、后半轴的同轴度。我们在修理中自制了一个专用工具,经几年的使用,效果很好。做法是: 选一个1140型柴油机的旧气缸套,考虑到活塞下止点位置气缸套内壁的磨损比上止点位置轻,为提高装配精度,在缸套的下部位置上开一缺口。开缺口时,先用手钢锯在缸套下部位置的一侧锯出两条相距35毫米,深60毫米的锯缝。再用手电钻在两锯缝底部之间钻5～6个φ5毫米的孔,然后用锤子敲掉中间部分,并用板锉将缺口锉整齐,
In the repair of the AK-10 starter, due to the lack of crankshaft assembly assembly special tools, it is difficult to ensure the coaxiality of the front and rear axle. We made a special tool in the repair, after several years of use, the effect is very good. The approach is: Select a 1140 diesel engine old cylinder liner, taking into account the bottom dead center piston liner wall wear than the top dead center position, in order to improve the assembly accuracy, the lower position in the cylinder liner to open a gap. When opening the notch, saw the two kerfs at 35 mm apart and 60 mm deep on one side of the lower part of the cylinder liner with a hand-operated hacksaw. Then drill with a drill in the bottom of the two kerf 5 ~ 6 holes φ5 mm, and then knock off the middle part with a hammer, and with a file filing will be neat file,
