(1)巧修高压油管。高压油管两端的凸头与喷油嘴、出油阀的连接靠接触面精度和螺母的紧固力来保证密封，如发现漏油，可从废气缸垫上剪下一圆形铜皮，中间挖一个小孔，垫在中间即可。 　　(2)巧拆减速齿轮外弹力挡圈。用一根细铁丝，一端穿过挡圈上的小孔后拧紧，另一端用改手 (1) clever repair of high-pressure tubing. High-pressure tubing at both ends of the nose and nozzle, the connection of the oil valve by the contact surface accuracy and nut tightening force to ensure that the seal, such as the discovery of oil spills, cut from the exhaust gas cylinder pad a circular copper skin, the middle dig A small hole, the pad can be in the middle. (2) cleverly demolish the reduction gear outer elastic ring. Use a thin wire, one end through the small hole on the ring after tightening, the other end to change hands
