一台1075型联合收割机在收获小麦时,转向失灵,只能向左转弯,不能向右转弯。经检查原来是方向机右侧安全阻油圈在装配时压偏了,只一个小边起作用,由于高压油的不断冲击造成液压油泄漏。当时车上没有备件,我们用直径2毫米的大阻油圈改制。将阻油圈用刀切断,绕在安全阀上按相应尺寸切成斜面,用502胶粘好。修复后使用四年多未发生故障。一台1075型联合收割机在 A Model 1075 harvester turned to failure when harvesting wheat, turning left and turning to the right.

At that time there was no spare parts on the car, and we reformed it with a large 2 mm diameter grease ring. The oil ring with a knife cut off, around the safety valve cut into the appropriate size of the bevel, with 502 good adhesive. Repair more than four years without failure. A 1075 combine harvester at
