Pulley pullers are tools used to install or remove mechanical pulleys and similar parts. They are used in various industries, including automotive repair, heavy equipment maintenance, and manufacturing. Different types of pullers are available, including hand jaw, harmonic, hydraulic, and pneumatic pullers. Universal pulley pullers are available, but jaw pulley puller sets are the most adaptable. These tools allow repair professionals to remove or install parts that are pressed into place at the factory.
Pulley puller is a term used to describe a category of tools used to install or remove various mechanical pulleys and similar pressed or pressed mechanical parts. While most commonly associated with the removal and installation of automotive pulleys, bearings, and gears, pulley puller tools are used in a variety of consumer and industrial applications. Typically, pullers are designed to grip and hold round parts that otherwise wouldn’t have clear gripping or prying points. Differing in size, construction, and function, most pulley pullers rely on carefully applied, stabilized back pressure to prevent damage to surrounding components or machinery when removing or installing pulleys, bearings, sprockets, or gears.
The need for a pulley puller is often dictated by a lack of strength required to remove or install a part. Many original equipment pulleys, gears, sprockets, and bearings are pressed into place at the factory when a particular machine or machine component is manufactured. Manual removal of such parts is often impossible. As such, a pulley puller makes up for the difference between the strength of hydraulic manufacturing equipment and the strength of a human repair professional. Pullers allow repair personnel to remove or install a replacement part previously assembled from powerful equipment, without the need for additional heavy manufacturing equipment.
Types of pulley pullers include hand jaw pullers, harmonic pullers, hydraulic pullers, pneumatic pullers, and numerous other models of pulley pullers for specific machinery and other applications. For automotive applications, pullers are often designed to remove or install only a specific part, such as power steering pumps, wheel bearings or harmonic balancers. In such cases, removing or installing a particular part requires a tool customized to fit a tight space with limited leverage points.
Universal pulley puller tools are available, but the universal designation refers primarily to various automakers or machine makers, rather than the ability to use the tool on a variety of pulleys, bearings, or other parts. Alternatively, a jaw pulley puller set is the most universally adaptable hand pulling tool, offering graduated sizes to suit a range of possible uses. These general purpose pulley pulling tools provide repair professionals with more universally applicable tools for use in a variety of environments, on a variety of industrial machines or automotive components.
While the automotive repair industry may be the most common user of pulley pulling tools, other industries require similar tools for heavy equipment maintenance and repair. To illustrate the wide and varied use of such tools, shipyards use hydraulic sheave pulling tools for the maintenance and repair of gears, bearings and sheaves used in commercial vessels. Manufacturing plants, such as steel and paper mills, use pulley pullers to maintain and repair process and assembly equipment.
