[QUOTE]How did you go about removing the copper cylinders from inside the aluminum? I have seen these before and the only way I could seperate them was with a lot of heat (a MAP gas torch) and then hammering on the copper?[QUOTE]







If you have a worn out but correct diameter socket, a hammer and either a oversize socket to set it on or a vise to hold it you're in business. Of course, a hydraulic press trumps that method. However, I like the ones such as the far left, bottom row, example in the photo. They are either held on by 4 tiny screws or some of the Aluminum heat sink is pushed through the holes forming a rivet type fastner. Either way, easy money.
