I just got done with swapping on a 2.76 pulley and got to use my new Billetflow puller/installer for the first time. Honestly I can not explain how well this tool works. I have heard about and seen many many problems with pulley installations and was expecting at least some grief, but let me tell you this was cake. I did the swap by myself in less than 15 minutes, that is how easy the pulley came off and the new one went on. I had read that this was the best tool, yada, yada, yada...., but after using it, No Sh!t this is the only tool to use period. You have to use one to believe how good this thing works, money well spent! Thanks Doug.
