辽宁51日—22型拖拉机在我省农村较多,大部分已转为农民个体经营,由于大多数农机户没有该机的使用说明书,所以凋整它的供油提前角非常困难。据我们实践,采用下述方法比较准确可靠。 1.找出第1缸活塞压缩行程上死点。将第1缸喷油器卸下,并在喷油泵高压油管接头上接上定时管,将油门放至最大供油位置,摇转曲轴,待定时管内油面上升的瞬间立即停止转动。用螺丝刀或细竹签从喷油器安装孔伸入汽缸内顶到活塞顶部。然后用手拉动风扇皮带使曲轴正、反方向轻轻转动,带动
Liaoning 51 -22 tractors in rural areas more, most of them have been converted to individual farmers, because most of the agricultural households do not have the machine’s manual, so it is difficult to adjust its fuel supply advance. According to our practice, the following method is more accurate and reliable. 1. Find the first cylinder piston compression stroke dead center. The first cylinder fuel injector removed, and the fuel pump high-pressure pipe fittings connected to the timing tube, the throttle to the maximum fuel supply position, crankshaft crankshaft, to be fixed at the moment of rising oil pipe immediately stop rotating. Use a screwdriver or thin bamboo stick to extend from the injector mounting hole into the cylinder to the top of the piston. Then hand fan belt to crank the crankshaft, the opposite direction gently rotate, driven
