description The invention relates to the technical field of manufacturing of engine parts, and discloses a press fitting method of a cylinder cover valve seat, which comprises the following steps: firstly press fitting a guide pipe, then press fitting the valve seat, when the valve seat is press-fitted and press fitting equipment is used, a valve seat pressure head adopts a floating fixing mode, when the valve seat is manually press-fitted, an unfixed mode is adopted, the outer circle of the valve seat is lubricated before press fitting, and in addition, the outer circle of the valve seat is lubricated before press fitting. A guide pin is designed at the front end of the valve seat pressure head, during press mounting, before the valve seat is pressed into a valve seat mounting hole of a cylinder cover, the guide pin is inserted into a guide pipe which is pressed into the cylinder cover, an inner hole of the pressed guide pipe is used as a guide hole of the valve seat pressure head, and finally, the valve seat is pressed
