The present disclosure generally relates to quick change attachments for a pneumatic percussive tool. The attachments convert a pneumatic percussive tool, such as an air impact tool with proximal attachment means, which has a pushing force, into a pneumatic percussive tool having a pulling force. Once attached to the pneumatic percussive tool, the attachments also provide a quick change feature for allowing pulling tools to be simply and easily removed and replaced.

A T-post puller with a channel providing a sliding fit over a T-post. The T-post puller when rotated relative to the T-post causes protrusions in the channel to engage the bottom of a T-post stud while a retractable member holds the T-post puller in stud engaging position. The T-post puller may be integrated with a T-post driver in a fencing tool including a drive tube for use in driving posts into the ground and for use as a slide hammer for extracting them from the ground.

A prior art powered wrist pin knocker is improved with a new plunger that prevents wobbling. The new plunger responds to a return vacuum pressure. The improved plunger is symmetrical along a longitudinal axis. New embodiments include a new side mount valve head to reduce length, a remote air controller and a variable length cylinder for the cannon. The new valve head is a simplified valve head assembly that adapts to an end of the cannon mount or a side mount or a remote mount. Another embodiment provides a stand for a surface mount application. This embodiment can have an extended piston for loosening tail bearings down a long channel. A manual return embodiment can use a rod to manually return the plunger to the proximal end for another firing cycle.

The present invention provides a means to achieve enhanced control of repair forces in the automotive body repair industry. In particular, the present invention provides a modified slide hammer and a method to achieve repair through the controlled application of forces otherwise not attainable with existing embodiments. Additionally, the present invention provides an ease of use and versatility of application and mounting at the site of the work in conjunction with and in line with existing devices used in the repair process. The application of the present invention provides increased reliability in the delivery of intended forces at the site of the work. Further, the inherent isolation of repair forces to the intended site of the work by the use of the present invention reduces the likelihood of secondary damage, material waste, or catastrophic failure thereby also enhancing the safety of the operator and the effectivity of repair. Specifically, the present invention may be implemented in conjunction with existing frame pullers in the automotive body repair industry to affect repair while providing facility to avoid obstructions in the path of applied forces.

A universal ball joint installation and removal tool kit for the purpose of service and repair or removal and installation of ball joint suspension components includes at least one tool assembly comprising a rod member having a first end and a second end, and a plurality of adapter members for mechanical attachment or engagement with respective ones of different sized ball joint suspension components. Each of the adapter members is configured to attach at the second end of the rod member. When servicing a ball joint suspension component, a selected adapter member is mechanically attached to a particular ball joint suspension component and attached at the second end of the rod member, which is used to install or remove the particular ball joint suspension component via a slidable weight along the rod member or pulling or pushing the rod member relative to the particular ball joint suspension component.

The invention involves the extraction process of a glow plug pencil (23) or a broken pencil (23) which is stuck in a cylinder head (13) housing (11) of a glow plug engine comprising a lower (19) and upper (17) part, so that the upper part (17) forms a shoulder (21) with the lower part (19), the pencil (23) being stuck in the lower part (19). The process is remarkable in that it includes a step (a) for drilling a bore in the pencil (23) according to the longitudinal direction of the latter which is performed with the use of a drill bit (1) comprising a drilling part (5) with flutes (7) and a shank (3) respectively having a diameter smaller and greater than the lower part diameter (19) of the housing (11) so that the shank (3) forms a shoulder (9) with the drilling part (5), and in that step a) for drilling the bore includes the drilling of the pencil (23) until the said shoulder (9) of the drill bit (1) is positioned to a stop against the shoulder (21) of the housing (11).

The present invention relates to a tool (1) comprising a handle element (101), a rod (103) which is firmly received in the handle element (101) and has a second stop (103a) at its end opposite the handle element (101), a weight (105) slidingly guided on the rod (103), which has a third stop (105a) on its side facing the handle element (101) and a fourth stop (105b) in its interior,
wherein the handle element (101) has a first stop (101a) at its end facing the weight (105), so that the weight (105) can be struck with its third stop (105a) against the first stop (101a) and alternatively with its fourth stop (105b) against the second stop (103a).

An installation tool for installing features and/or components involving a grommet onto a water containing structure assembly, and a method of use thereof, which facilitates controlled and precise application of an insertion force. The tool actively prevents or reduces the unintentional application of the insertion force onto anything surrounding the grommet. The tool, and a method of use thereof, may have an insertion force generating sub-system configured to mechanically drive a grommet-based component into the grommet, and an engagement sub-system configured to translate and impart the insertion force from the insertion force generating sub-system to the grommet-based component and the grommet. The tool may have a sturdy, stable, and slide-hammer configuration or a basic tamp configuration for use with a mallet. The slide-hammer may comprise an anvil sub-system and a hammer sub-system in a reciprocating configuration. A complimentary puller tool may be included.
