《农业机械资料》1974年11期中《缸盖螺栓拧得越紧越好吗》一文,说的是有的修理人员随意加大气缸盖螺栓的扭紧力矩,造成缸体螺栓孔周围被拉得凸起,缸体平面翘曲,出现漏水漏气。这种随意加大气缸盖螺栓、连杆螺栓等重要螺栓的扭紧力矩,造成意外损失的现象我们也遇到过。有一次,我们修理一台东方红-54拖拉机,用了一米多长的加力杆根费劲地才将连杆螺母松开。这样随意加大连杆螺栓的扭紧力矩,会
“Agricultural Machinery Information” in 1974 eleventh “cylinder head screw tighter and better” article, saying that some repairers feel free to increase the cylinder head bolt tightening torque, resulting in around the cylinder bolt hole is pulled Protrusion, cylinder plane warpage, there leakage leakage. This arbitrarily increase the cylinder head bolts, connecting bolts and other important bolts tightening torque, resulting in accidental loss of the phenomenon we have encountered. Once, we repaired a Dongfanghong-54 tractor, with a length of more than one meter afterburner rod effortlessly to release the connecting rod nut. This arbitrarily increase the torque of the connecting rod bolt will be
