A bit holder can include a body and a collar. The body can be mountable to a rotor of a piece of equipment. The collar can be coupled to the body and can be configured to receive the bit therein. The collar can include a first flat collar surface forming a portion of a radially outer surface of the collar and a second flat collar surface forming a portion of the radially outer surface of the collar.

A method of disassembling a surgical instrument includes obtaining a surgical instrument including a housing, an input shaft defining an axis and extending from the housing, and a paddle engaged with the input shaft and configured to pivot about the axis. The method further includes disengaging a cover plate of the paddle from a body of the paddle by providing a force to the cover plate substantially in a direction parallel to the axis and disengaging the body from the input shaft by providing a force to the body substantially in a direction parallel to the axis.

A tool and an associated process for removing a press-fit component from an associated engine component, wherein the engine component is pushed in a first axial direction while the press-fit component is restrained from axially moving in the first axial direction.

A system for disengaging a drive shaft from a bearing support. An assembly formed by the drive shaft and the bearing support is placed above a cylinder, which pushes on the drive shaft by passing by the central hole of the bearing support. The bearing support is driven upwards, but is blocked by a first and a second force transfer device, which allows the drive shaft to be disengaged from the bearing support.

A disassembling device for removing fastening components embedded in a workpiece includes a supporting base, a clamping assembly, and a pushing assembly. The pushing assembly includes a sliding assembly, an adjusting rod, and an ejecting pin. The workpiece defines a first through hole which communicates with a positioning hole. The workpiece is clamped by the clamping assembly, the sliding assembly is connected to the supporting base and can slide along a first direction and a second direction perpendicular to the first direction. The adjusting rod passes through the sliding assembly to connect with the ejecting pin, the ejecting pin is driven to extend into the first through hole and to move in a direction perpendicular to the first and second directions, so as to push the fastening component out of the positioning hole.

A valve seat puller provides jaws for expanding on a first side of a valve seat to engage that seat in a first reaction for removal of the seat in a second direction.

A bit holder can include a body and a collar. The body can be mountable to a rotor of a piece of equipment. The collar can be coupled to the body and can be configured to receive the bit therein. The collar can include a first flat collar surface forming a portion of a radially outer surface of the collar and a second flat collar surface forming a portion of the radially outer surface of the collar.

In accordance with embodiments of the invention there is provided an extraction system, and extraction apparatus (30) and method therefore in for removing studs from sockets. The system is particularly advantageous for removing one or more studs (28) from the sockets (24) of bell cranks (16) of steering systems of vehicles such as an Off-highway Truck. In a particular arrangement the apparatus (30) comprises a frame member (32) adapted to be attached to a pivot joint (14) for extraction of the stud (28) from the socket (16). Furthermore, the apparatus 30 comprises actuator means (34) adapted to be selectively displaced between an extended condition and a contracted condition for applying a force to the stud (28) so as extract or at least loosen the stud (28) from the socket (36). In a particular arrangement, the actuator (34) comprises a hydraulic actuator. The system is adapted to remotely operate the extraction apparatus (30).

A method of restoring a wheel (1) to compliance, the wheel having a plurality of ovalized bores (2). The method is characterized in that it includes at least a step of boring a first ovalized bore (2) with the help of a reamer (3) presenting a longitudinal pilot portion (3a) and a longitudinal cutter portion (3b), the cutter portion (3b) presenting teeth (4) defining a cutting diameter (D2), and the pilot portion (3a) presenting a pilot diameter (D1) strictly less than the cutting diameter (D2), the step of boring this first ovalized bore (2) consisting in inserting the reamer (3) into the first ovalized bore (2), beginning with the pilot portion (3a) and followed by the cutter portion (3b), the pilot diameter (D1) being such that it enables the reamer (3) to be guided in translation inside the first ovalized bore (2) for boring.

A system for extracting an assembly component from an assembly uses an extractor that applies a gripping force around a perimeter of the assembly component, a coupler that applies an extraction force to the extractor and a tensioner fastened to the coupler that generates the extraction force, the extraction force causing the assembly component to slide out of the assembly. The tensioner applies an extraction force to the extractor which pulls the assembly component from the assembly.
