-14- Abstract of the Disclosure Engine Barring Device Engine barring devices are connected to engines. Known barring devices have been used to rotate flywheels having a plurality of external teeth connected to crankshafts of engines. The engines have a starting system including a source of pressurized fluid, a starting motor and a conduit connected to the source of pressurized fluid to the starting motor. The subject barring device includes a housing having a through bore, and a shaft adapted for both axial and rotational movement within the bore. A gear is attached to one end of the shaft and is moved axially in a first direction to a first position in which the gear is arranged to engage in driving relationship with the flywheel. A holding device holds the shaft in the first position while leaving the shaft free for rotational movement. A tool engaging portion located on the shaft is adapted to engage with a turning tool. With the shaft in the first position, the turning tool can be used to rotae the crankshaft of the engine. A device is provided for disabling the system when the shaft is in the first position and includes a device for blocking the conduit between the source of pressurized fluid and the fluid starting motor.
