Review on Shankly Harmonic Bearing and Gear Pulley Puller with Dual Jaws for Maximum Efficiency by Hayden Hart

Poorly designed tool. The arms do not have enough lateral support to prevent them from "swaying" during the pull. So the flat teeth on the end will come loose and you will have to reinstall the puller. You can get around this by using a large heatsink style zip tie to hold the clamps closed and tight to the component you are pulling on. In addition, the teeth on the handles and grips are too fine, resulting in a lack of grip. Just another Chinese low-level tool that doesn't work properly without modifications. For a little more money they could build an instrument that works and be paid accordingly, but that would bring a sense of honor and decency long gone by the greedy friends who run the show. Unless you want to modify and/or remodel, stay away. .Master car mechanic and truck 1988-today
