汽车维修工在进行换环保养时,拆下活塞连杆总成后,一般应逐个在活塞顶部及轴承盖上打上缸序记号,以保证原有的配合和配对关系。但有时会忘记在轴承盖上作配对记号,这样在清洗中,很容易把轴承盖张冠李戴。如果不及时调整过来而直接装配试车,就会加剧轴承的磨损,甚至把轴承烧坏。现提供两种还原方法供参考。 1.有千分尺及内径量表时,则只需装上轴承盖,按规定力矩扭紧连杆螺栓,然后,测量轴承座孔,其圆度
Car maintenance workers in the ring for maintenance, remove the piston connecting rod assembly, the general should be one by one in the top of the piston and the bearing cover marked with a cylinder order to ensure the original relationship and matching. But sometimes forget to make a matching mark on the bearing cover, so cleaning, it is easy to wear the bearing cap. If not adjusted in time and directly assembled test run, it will exacerbate the bearing wear and tear, or even burn the bearings. Now provide two reduction methods for reference. 1. Micrometer and internal diameter scale, then only need to install the bearing cover, according to the required torque to tighten the connecting rod bolt, and then measuring bearing hole, its roundness
