A mechanical puller is a small tool whose main use is to help an operator extract gears, pulleys or bearings that are impossible to remove using only the force of the hands. When buying an extractor, the size of the part to be extracted must be taken into account, since the tool must be perfectly adjusted to the size of it, so that neither one nor the other is damaged in the extraction process.
A universal puller, the 3-jaw puller has three articulated arms that have internal and external hooks. You can use them to remove gears, pulleys, wheel hubs, all kinds of hard-to-remove parts. They come in various sizes and are inexpensive.
Each garage should have three sizes of 3-jaw mechanical pullers in the drawer. Like tie rod tools, the center stud threads in to get the job done.
