Abstract: Pin insertion and removal tool includes a main block and a holder cup or socket for holding a pin to be inserted to secure a tooth onto a shank of a bucket. The holder cup or socket is secured to a holder block which is in turn secured to the main block. An extractor pin is secured to an extractor block, and the extractor block is secured to the main block. Both the extractor pin and the holder cup or socket are spaced apart from the main block by predetermined distances. The main block includes impact portions which receive hammer blows to set the pin and to remove the pin, as required. Adjacent to the holder cup or socket is a pin setting face that is used to completely insert the pin after it has been started and is sufficiently into the tooth and shank to remove the socket and tool from the pin and to move the tool slightly to provide direct force against the pin for setting the pin by hammer blows on the pin setting impact portion of the main block.
