ABSTRACT:
This bearing carrier puller for extracting a bearing carrier from a lower gear case of a marine drivetrain consists of three components: a boss which envelopes a propeller shaft and is secured to it by a nut and washer; a block which bears against a lower gear case of a marine drivetrain; and a nut which threads over the boss and bears against the block to extract a bearing carrier. A first disclosed improvement prevents rotation of the boss relative to the block by means of structural configurations on the mating surfaces of the block and boss. A second improvement prevents the boss from being drawn through the block beyond a desired point by means of a stop. An additional embodiment of the second improvement prevents the nut from traveling on the boss in the direction of a first end beyond a desired point by means of a stop. A third improvement enhances gripping of the block with a wrench by means of a polygonal surface configuration extending along the periphery of the block from its' second end.
