小四轮拖拉机发生连续烧瓦,一是由于机油油路堵塞,二是由于润滑不良。油路堵塞烧瓦表现为,第一次烧瓦后,检诊为油路堵塞所致。清理更换后重新起动运行,行驶不久又发生烧瓦。再次摇车检查,发现机油油路又堵塞。润滑不良烧瓦表现为,两次烧瓦都是靠飞轮一侧的主轴瓦烧损。检查润滑系统工作正常,只是在安上三角带后,摇转曲轴非常吃力,查找离合器至变速箱间传动无任何异常。 Small four-wheel tractor continuous burning tile, one due to blockage of the oil circuit, and second, due to poor lubrication.
