And when you apply all the pressure you can to it (and this one was 15 ton, you "Might" get by with a 5 ton, not sure), it still may not "pop" off. DO NOT STAND DIRECTLY IN FRONT OF IT AS IT WILL HIT YOU HARD WHEN IT DOES LET LOOSE! apply as much pressure as you can by hand, then stand off to the side and hit the hub with a heavy hammer. it WILL throw the jack across the floor when it goes, so be ready and not in the way. I think they use sleeve retainer on those hubs, just my thoughts. Anyway, make sure nothing you value is to the side of the Roxor when you try this, you may regret it. the jack flies about 4 feet. Ask me how I know...
