Abstract: <正> 东方红-60T推土机旧式油缸活塞杆导向套用三瓣爪或压盖定位。新式油缸活塞杆导向套改为卡簧定位:油缸内径和导向套外径均有卡簧槽,为了便于拆装,油缸上对正卡簧槽处有与槽相通的弧形开口;导向套上有卡簧爪孔;卡簧一端有爪,另一端有拔梢。安装时,将导向套装入油缸,转动导向套,当导向套卡簧爪孔与油缸弧形开口对正时,把卡簧爪插入导向套孔,再转动导向套,使卡簧进入油缸与导向套卡簧槽内。导向套可右转,也可左转。若右转,卡簧拔梢端应在左;若左转,卡簧拔梢端应在右。拆卸、安装时导向套若是右转,拆卸时就应左转,转动时拔梢端便可从油缸弧形开口处退出,不易退出时,可用有尖的合适铁钉等引导。当转至导向套卡簧爪孔与弧形开口对正时,可将卡簧取下,最后取出导向套。新式油缸拆装简化了。但由于卡簧质量差、或对结构不了解、或拆装不得要领,卡簧爪折断便成了常见的故障。卡簧爪折断后,转动导向套时,卡簧不随着转动,卡簧无法退出。这时,可用钻钻断;无钻时,可将三
