The invention relates to the technical field of engine maintenance and repair and in particular discloses an engine crankshaft jacking tool for lifting a crankshaft. The engine crankshaft jacking tool comprises a supporting seat and a lifting mechanism, wherein the supporting seat is arranged on a cylinder below the crankshaft; the lifting mechanism comprises a plurality of lifting devices, the lower ends of the lifting devices are slidably matched with the supporting seat through a sliding assembly and the upper ends of the lifting devices abut against the crankshaft. The separation distances among the plurality of lifting devices can be adjusted by sliding fit, so that crankshafts of different models can be further lifted, and therefore, the application range can be further expanded.

    本发明涉及发动机维修保养工具技术领域,具体公开了一种发动机曲轴顶升工具,用于对曲轴的抬升,发动机曲轴顶升工具包括支撑座和抬升机构,支撑座置于曲轴下方缸体上;抬升机构包括多个抬升装置,抬升装置下端与支撑座通过滑动组件滑动配合,抬升装置上端与曲轴抵接,通过滑动配合可以调整多个抬升装置之间的间距,进而可以对不同型号曲轴的抬升,可进一步扩大使用范围。
