A crank guide assembly for an internal combustion engine with facing cylinders includes a crank guide defining an opening with a pair of opposed long sides and a pair of opposed short sides extending between the long sides. The long sides guide the sliding piece on a crankshaft. A replaceable base plate is mounted on each of the long sides and locking plates, disposed parallel to the short sides, hold the base plates on the long sides.
