I used this to remove timing gears off of a 1926 Fordson Tractor engine. I had tried a conventional puller (two jaw) and used heat, penetrating oil, brass hammer, etc. Nothing worked. Once I had this puller assembled and set up, the gears were removed in less than two minutes. I like that the jaws are reversible with hooked and square cut ends as well as the adjustment collar is designed to use two or all three jaws; this is very versitle, especially when space is limited on what you are working on. It is priced right for the home shop, hobby mechanic, etc. I don't know how often I'll use something like this tool, but, it saved me on one job and I am quite satisfied.
