Review on 8MILELAKE 50mm Hex Crankshaft Crank Damper Pulley Holding Wrench Socket Tool - Ideal for Honda Acura Cars by Mack Cruz

If you use some tape to make it a little thicker, it will fit better in the hex hole in the pulley. If using a 1/2" square hole for the ratchet, push the ratchet handle back through the hex. This will prevent it from binding and shifting and then detaching or falling out. PB Whip this shit a day before you get to work, supposedly they don't get stuck like that sometimes but I had to take the bumper off and set it on fire for a minute and make sure you have a cheat bar over 3ft long have and a break bar . It happens to be 19mm, so will fit with a tire tool or four-sided tool. Much luck!?
