After rotating the internal combustion engine 50 by a predetermined angle, the locking pin 12 is rotated using the force of the spring 13.
is engaged with the newly opposed locking hole 15, and the internal combustion engine 50 becomes fixed in a predetermined inclined position. In the state shown in FIG. 2, the water supply hose 64
, fuel hose, exhaust hose, etc. are connected. Then, the internal combustion engine 50 is tested, and is first started and operated. If the internal combustion engine 50 has a starter motor, the starter motor is used to perform the starting motion in the state shown in FIG. If the starter motor does not have a starting motor, the output shaft 60 is advanced and the spline shaft 61 is fitted into the spline hole 36, and the output shaft 60 is rotationally driven. Then output shaft 6
The zero rotation is transmitted to the main shaft 54 via the intermediate shaft 35, the power transmission section 37, and the flywheel 55, and the main shaft 54 is rotated to perform a starting motion. After the internal combustion engine 50 enters normal operation, the spline shaft 61 is removed.
