Abstract: A socket wrench driven adjustable jaw crow foot wrench is an assembly of four primary components: a chassis; a carriage; a ratchet; and a pawl. The chassis has a stationary jaw at a first end, a track extending from the first end to a second end of the chassis; and a cavity which opens to the track and opposing sides of the chassis. In a preferred embodiment of the tool, a female receiver for a socket wrench is provided on an end of the tool opposite the track. The carriage bears a jaw designed to mate to the stationary jaw of the chassis. The carriage is provided with a rack. Said carriage is designed to travel in the track provided on the chassis. The ratchet is provided with a female socket wrench receiver, and is located in the cavity provided in the chassis. The ratchet is juxtapositioned to communicate with the rack on the carriage. The pawl is located in the cavity provided in the chassis and juxtapositioned to communicate with the ratchet.

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.
