Hydraulic main bearing cap dismounting tool and using method thereof

The invention provides a hydraulic main bearing cap dismounting tool and a using method thereof. The dismounting tool comprises a hydraulic cylinder, a transverse connecting plate, a fixing rod, a hydraulic cylinder piston rod, a connecting block, a connecting bolt and an external threaded rod. The dismounting tool is fixed on the main bearing cover, the hydraulic cylinder piston rod is driven to move up and down through the hydraulic pump, then the main bearing cover is driven to move up and down, and on the premise that the main bearing cover is not completely dismounted, replacement of the main bearing bush is completed. According to the hydraulic type main bearing cover disassembling tool, the descending action of the main bearing cover can be completed in a narrow crankcase space, the main bearing cover can be simply and conveniently reassembled, and the difficulty and workload of replacing a main bearing bush are greatly reduced. 本发明提供了一种液压式主轴承盖拆卸工具及其使用方法，拆卸工具包括液压缸、横向连接板、固定杆、液压缸活塞杆、连接块、连接螺栓和外螺纹杆。拆卸工具固定在
