Abstract: A pressing tool for plastically deforming a workpiece is described. The pressing tool includes a housing and an electric motor for actuating the pressing tool. The pressing tool also includes an instrument seat which is adapted to receive an interchangeable instrument head at the housing. The pressing tool also includes a mechanical safety element which is arranged in a manner that is movable from an open position, in which an instrument head may be inserted into the instrument seat, into a closed position, in which the instrument head is locked in the instrument seat. The pressing tool additionally includes a mechanical actuating element which may interact with the safety element in order to be able to cause the pressing tool to be enabled for a pressing process.

Abstract: A powered tool for removing mechanical fasteners from materials. The fastener removal tool includes: a fastener puller for engaging the head of a fastener; a stand-off mount for placing against a surface having a fastener therein; a rod joined to the fastener puller; and a power source operatively connected to the rod. The fastener removal tool may exert a pulling force on the head of a fastener in the form of repeating intermittent strikes on the underside of the head of a fastener with said fastener puller. The fastener removal tool may have an indicator mechanism for indicating whether the fastener puller completely engages a fastener. The fastener removal tool may have a fastener lubricating system for lubricating difficult to remove fasteners.

Abstract: A circular hydraulic press reforms and resizes a chamber opening in a combustion chamber housing. The press comprises a bar having a U-shaped end and a pair of free ends. The press comprises a panel having a C-shaped edge, a mounting edge, and a pair of slotted edges. The U-shaped end of the bar and the C-shaped edge of the panel buttress the perimeter of the chamber opening. The slotted edges and a pair of tubes on the slotted edges slidably receive the free ends of the bar to enable displacement of the panel towards the bar. A disk having a predetermined annular shape and circumference positions in the chamber opening. A hydraulic piston displaces the C-shaped edge of the panel towards the U-shaped end of the bar to press the chamber opening against the disk, and thereby reform the disk to substantially the same shape and circumference as the disk.

Abstract: A wheel stud press assembly comprising a frame assembly comprising a frame member and a drive system comprising a drive rod. The drive system is supported by a shoulder portion of the frame member to displace the drive rod along the drive axis. The frame member is configured such that, when and anchor member is detachably attached to the frame member, the drive axis is offset from the main portion of the frame member. When the drive rod engages the wheel stud to force the wheel stud out of the wheel opening, at least a portion of the anchor member engages wheel flange adjacent to the wheel stud to allow the wheel stud to be forced out of the wheel opening, and the anchor portion is offset from the drive axis to allow the wheel stud to be displaced out of the wheel opening.

Abstract: A puller for pulling an element, such as a pulley or seal, from an assembly to which it is fitted. The puller generally includes a central body having a longitudinal axis, an adjustment ring threaded on the body for moving longitudinally with rotation, slide followers coupled to the ring and moving longitudinally with ring rotation, a plurality of leg assemblies, each including a foot and two legs pivotly attaching the foot to the body so as to form a parallelogram, and a arm pivotly connecting each slide follower to a leg assembly for expanding or contracting the leg assembly. Each foot has one or more foot flanges, each with an engagement surface for engaging with the element to be pulled; the orientation of the engagement surfaces being predetermined so as to not disengage from the element and to provide uniform pull and minimum pressure.
