    Abstract: A brush holder assembly that, by design, cannot be assembly incorrectly is disclosed. The brush holder assembly includes a brush inserted into a brush holder, a block attached to the top of the brush, a spring engaging the block so as to apply radial pressure to the block and brush, and a hook pin engaging the spring and the block so as to hold the spring onto the block. The block includes a semicircular indentation that cradles a coiled portion of the spring. The block also includes a slotted hole for receiving a portion of the hook pin as the block is glued to the top of the brush. The hook pin is preferably a loop terminating at a first end that is a substantially straight pin and terminating at a second end that is a hook-shaped loop in which the straight pin end is inserted. The hook pin is formed from a spring biased metal to facilitate insertion of the straight pin end and into the hook-shaped loop end.
