The release bearing 154 presses the clutch release lever 534, moves the clutch plate 530 against the spring, and forms the gap G between the clutch plate 530 and the clutch disc 540. As a result, the engagement between the clutch cover and the clutch plate is released. Therefore, the engine is operated without load. By operating the engine with no load, it is possible to test noise and vibration in each rotation range. Further, it is possible to test the power characteristics and the like when the clutch is operated by engaging the clutch in a half-clutch state or disengaging the clutch. When the engine performance measurement is completed, the crank 44 that fixes the engine pallet 55 to the test bench 40 is opened, and the engine pallet is automatically conveyed to the next process via the path P3.
