An installation tool and installation method for fixing pins. In the mounting tool a cavity is provided in a tube body for accommodating a plurality of fixing pins. A first sliding groove and a second sliding groove are provided opposite each other and connected to the cavity. A first opening and a second opening are provided in two ends of the tube body. A pressing pin passes through the sliding grooves and is movably arranged on the tube body. The driving nut is adapted to driving the pressing pin to move towards the second opening.

Wheel weight pliers contains: a first lever, a second lever, a connection shaft, and a spring. The first lever includes a first grip section and a first work section. The second lever includes a second grip section, a second work section, and a third work section. The first work section has a hook, and a width of two sides of the hook decreases from a root of the hook to a distal end of the hook. The second work section has a blade portion, and the third work section has a hammer. The hammer has a fitting element. The first grip section has multiple recesses adjacent to the second grip section. Two ends of a respective one recess extend on two sides of the first grip section. The second grip section has a notch formed proximate to the first grip section, and the notch faces the multiple toothed ribs.

An installation tool for an airfoil trim balance weight includes a tool body having a support for supporting the tool body with respect to the trim balance weight. A linear actuator is provided for contacting a tab of the trim balance weight, the linear actuator for moving linearly with respect to the tool body in a linear motion toward the support to permit the tab to bend. A method for installation, a gas turbine engine and a method for manufacturing also are provided.

A fixture for sticking balance blocks to the surface of a hub includes a base, in which a fixed plate is welded to one side of the upper end of the base, a slide rail butted to the fixed plate is connected to the other side of the base by bolts, a sliding block is connected to the slide rail in a sliding manner, the middle positions of the fixed plate and the sliding block are respectively connected with a first roller and a second roller of the same type by bearings, each of the first roller and the second roller is sleeved with a rubber sleeve of the same specification, and a support table is mounted under the base.

A tool is configured to install a tire pressure monitoring (TPM) sensor in a tire rim of a vehicle tire. The tool includes a lever having a rotational movement about a rotational axis; a cam selectively coupled to the lever; and a push pin selectively coupled to the cam. The cam translates the rotational movement of the lever into a liner or translational movement of the push pin. The linear or translational movement is effective to impact or move a roll pin of a tire pressure monitoring (TPM) sensor disposed at the tool, such that portions of the TPM sensor or pushed through an opening in a tire rim.

A tool attachment configured to remove a wheel weight from a vehicle wheel is disclosed. The tool attachment comprising a body. The body include an exterior surface, a first end, and a second end. A mounting surface is positioned on a first portion of the body proximate to the first end. The mounting surface is configured to abut a tool. An opening extends from the mounting surface to the exterior surface of the body. The opening is configured to receive a fastener to secure the body to the tool. A blade engage surface is positioned on a second portion of the body proximate to the second end. The blade engaging surface is configured to receive and secure a blade to the body. A tool including the tool attachment and a method of using the tool attachment are also disclosed.

A knock-on wheel weight tool for installing or removing a wheel weight with a metal clip on a wheel rim. The knock-on wheel weight tool includes a shaft component, a wheel-weight installation head removably attached to the shaft component, the wheel-weight installation head including a wheel weight clip contact area shaped to receive the metal clip of the wheel weight. The knock-on wheel weight tool also includes a weighted slide handle with a shaft hole sized to receive the shaft component, allowing the weighted slide handle to slide back and forth on the shaft component. A user slides the weighted slide handle along the shaft component to strike the wheel-weight installation head which in turn snaps the metal clip of the wheel weight onto the wheel rim.
