A set of mechanisms, for use with an internal combustion test engine, for testing cylinder offset during operation of the engine. The test engine specifics may vary, but it is assumed to have a crankcase base that supports a cylinder barrel and cylinder head. During engine operation, a transit plate is secured to the top surface of the crankshaft base, and a pair of wedge plates is secured between the transit plate and the bottom of the cylinder barrel. When the engine is not in operation, the transit plate can be slid in a direction normal to the crankshaft axis (for cylinder offset adjustment), and the wedge plates can be moved relative to each other (for cylinder height adjustment).
