A tool for retracting pistons into cylinder bores is disclosed, with a narrow gap between facing pressure plates allowing use of the tool in tight places, and ratcheting spreading of the facing pressure plates causing outward moving of the pistons, enabling work to be performed, wherein movement of a threaded stud through a coupler moves a first pressure plate.

A ball joint press includes a first frame including a first member and a first adaptor, and a second frame including a second member and a second adaptor. A link is pivotally coupled to the first member and to the second the second member. An actuating screw is rotatably coupled to the first member and to the second member. Rotation of the actuating screw in a first rotational direction causes the first member and second member to undergo a first pivoting action relative to the link to move the first adaptor toward the second adaptor. Rotation of the actuating screw in a second rotational direction opposite the first rotational direction causes the first member and second member to undergo a second pivoting action relative to the link, opposite to the first pivot action, to move the first adaptor away from the second adaptor.

A multi-head, rack and pinion driven pulley puller including a rack and pinion drive assembly. The drive assembly includes a body member, a rack shaft, and a pinion gear, enclosed in the body member in one embodiment. The drive assembly further has a head that is adapted to receive a variety of puller assemblies, including a pivoting jaw puller assembly and a forked plate puller assembly.

A panel fastener tool is disclosed that includes a first arm pivotally connected to a second arm. Each of the first arm and second arm include a camming portion, a camming surface, a terminal projection projecting substantially inwardly, and an indent between the camming portion and the terminal projection. Upon pivoting the first arm and the second arm towards each other, the camming surfaces each engage a top portion of an inner member of a fastener inserted into a hole in a workpiece. The camming surfaces lift the inner member out of an insertable member of the fastener, and the terminal projections capture a head portion of the insertable member within the indents. When an upward force is applied, the terminal projections lift the insertable member from the hole.

A removal device for a belt pulley contains: a guiding rod, two clamping members, and two paws. The guiding rod includes a screwing hole defined on a central position thereof to screw with a push rod. The two clamping members slide along the guiding rod, and each clamping member includes a guide orifice for inserting the guiding rod, a first guide rail, and a first engaging portion, wherein a first direction of the first guide rail is perpendicular to a second direction of the screwing hole. Each paw includes a second guide rail for matching with the first guide rail, such that each of the two paws is connected with or removed from each of the two clamping members, wherein the second guide rail has a second engaging portion for cooperating with the first engaging portion.

A cup plug insertion tool comprises a cylindrical base and a cylindrical collet extending from the base and including at least two longitudinal slots that divide the collet into at least two flexible segments adapted to flex radially inward under force, an annular groove formed adjacent the base, the annular groove adapted to allow the flexible segments to flex radially inward, further wherein, the force necessary to flex the flexible segments radially inward is tunable based on a width and depth of the annular groove, a first section defining a circumferential outer diameter and a circumferential inner diameter, a second section defining a circumferential outer diameter that is larger than the circumferential outer diameter of the first section, a tip positioned at the distal end of the collet, and a chamfer formed between the outer diameter of the first section and the tip.
