ABSTRACT:
A punch alignment sleeve that fits over the hub of a fan blade assembly or pulley wheel. The punch alignment sleeve has an internal channel which is aligned with and slidably fits over the end of the motor shaft. It has an internal channel running from the end of the motor shaft on the distal end to an aperture on the proximal end which slidably receives a punch. The punch alignment sleeve is held in place on the hub by a recessed area which fits around the periphery of the hub. The punch is struck to jolt the motor shaft loose after the punch alignment sleeve is installed. The internal channel is sized to snugly and slidably hold the shaft end and punch in position such that the shaft is struck by the punch at an angle substantially aligned with its longitudinal axis. The punch alignment sleeve also has optional and removable hub insert sleeves which allow the device to fit multiple size hubs. An optional slot in the side of the distal end of the punch alignment sleeve allows it to fit over a retaining screw in the side of the hub. An optional shaft driver has a cone shaped recess that prevents the shaft tip from mushrooming when struck.
