I have one of these and it quit working years ago. I can't seem to be able to take it apart. Anyone ever been able to repair this model or do I recycle it?

I have an old Mt. Zefal pump and to open the piston you just unscrew the it at the top of the pump beneath the handle. What part are you trying to take apart? the piston or head?

This is the full size frame pump. I just managed to pull it apart after unscrewing the barrel. This is the one that pumps on both strokes. To get it to seperate into two pieces takes a fair amount of force.
