This paper presents the design and operating principle of a mechanical device for ma-chining a cylinder liner flange seat in a diesel engine damaged due to cavitation or wear. Mounted on the engine block, the device allows the removal of damaged material and the formation of an undercut for the installation of repair rings. The gear ratios used allow for manual driving of the device. The device allows engine repair without the need for disassembly, which provides significant economic benefits by shortening repair time, reducing repair costs, and extending engine life, which is also important for environ-mental protection.
