PROBLEM TO BE SOLVED: To provide a diagnostic device for transmission of working machine capable of avoiding a large trouble from being developed by allowing users to easily recognize a premature defect and capable of contributing to the improvement of a product. SOLUTION: A vibration detection sensor is fitted to a transmission case near the bearing part thereof, the detected results of the vibration detection sensor are inputted into a micro computer mounted on a body, and it is determined whether side band wave occurs or not in detected vibration information. The diagnostic treatment for presence or absence of any abnormality is performed by discriminating the side band wave level occurred. COPYRIGHT: (C)2004,JPO |
