ABSTRACT:
An apparatus for press-fitting a bearing cap into a cylinder block includes a frame. A first cylinder is connected to the frame. A guide rod is coupled to an operating rod of the first cylinder to ascend or descend in response to an operation of the first cylinder and configured to be inserted into bolt holes respectively formed in the bearing cap and the cylinder block in response to a descending thereof. A second cylinder is connected to the frame. A pressure detection sensor detects an operating pressure generated by the second cylinder. A press pad is coupled to an operating rod of the second cylinder to ascend or descend in response to an operation of the second cylinder and configured to press the bearing cap so that the bearing cap is press-fitted into the cylinder block.
