ABSTRACT:
An engine barring system is disclosed that includes a barring device having a drive shaft manually engageable with the flywheel of an engine to rotate the engine crankshaft. An electric motor is coupled to the drive shaft of the barring device and incrementally rotates the drive shaft in response to forward and reverse signals. A controller supplies the forward and reverse signals in response to manual input by a user. The controller is portable about the engine so that the user can incrementally advance or reverse the crankshaft while observing the crankshaft rotation away from the barring device. A reduction gear box is coupled between the motor and the barring device to reduce the drive shaft speed from the motor speed and also provide torque multiplication between the motor and drive shaft. The torque multiplication serves as an effective lock to prevent movement of the crankshaft when the barring device is engaged.
