装有195柴油机的小型拖拉机手摇起动时,在供油时间、喷油雾化、气缸压力均正常的情况下,摇动沉重,起动困难。原因:(1)曲轴轴向间隙太小。在主轴承盖与机体结合面上增加纸垫,把间隙调到0.15～0.40mm。(2)连杆轴瓦间隙太小或瓦口处有高点支承。拆下活塞连杆组,摇动曲轴,如果灵活,
Small tractor equipped with 195 diesel engine crank start, in the fuel supply time, spray atomization, the cylinder pressure are normal circumstances, shaking heavy, difficult to start. Reason: (1) Crankshaft axial clearance is too small. In the main bearing cap and the body to increase the surface of the paper pad, the gap transferred to 0.15 ~ 0.40mm. (2) connecting rod bearing clearance is too small or watts at the high point of support. Remove the piston rod group, shake the crankshaft, if flexible,
