Abstract:
1. A method for disengaging a shrink coupling that secures a shaft to a drive train component, comprising: erecting a reaction plate around the shaft at a location axially displaced from the shrink coupling; disposing a plurality of jacking devices between the reaction plate and the shrink coupling, the jacking devices circumferentially spaced around the shaft and having a first end engaged against the reaction plate and a second opposite end in a pull-engagement configuration with the shrink coupling; releasing the shrink coupling from its clamped state; and activating the jacking devices to exert a pulling force on the shrink coupling, wherein the shrink coupling is pulled off of the drive train component axially along the shaft to a resting position on the shaft.
