Abstract
A method and apparatus involving releasing the rotor ( ) and turning it to and fixing it at top dead center, attaching an extractor head to an exposed end of the hammer axle. A cross-piece ( ) is applied and a releasable element of a slide ( ) of a hammer axle puller is pulled, making a releasable connection between cross-piece and rotor attachment elements. The slide is moved to a position in which the puller head is connected to the slide in a shape-locking manner, securing the hammer position, returning the carriage whilst extracting the hammer axle ( ) to release the hammer. The connection between the head and slide is released, moving the slide until the head and slide re-engage and returning the slide again to extract the hammer axle until the entire hammer and/or protective cap ( ) and axle if appropriate are extracted. An Independent claim is also included for an arrangement for implementing the method.
