Abstract
A remote operated turning gear engager for rotating a turbomachine rotor is disclosed. Pressurized oil is selectively supplied to displace a piston to engage the turning gear with the rotor. Electrical sensing means are utilized to verify that the turning gear is in the appropriate position. Additional control means are provided for discontinuing turning gear operation should insufficient oil be supplied to the bearings. Other circuit means prevent operation of the turning gear should the rotor be rotating and allow for a bypass of this safety feature for positioning the rotor for service requirements.
