CCW= Counter Clock Wise. The can is not threaded, just probably stuck. I said turn the can CCW just so it does not retighten the bolt. The bolt is captive and spring loaded to the can and wants to turn with it due to that. Turning of the can is just to break it loose from anything binding it. Because bolt is spring loaded, (to up) it is somewhat difficult to see that it is loose from the threads in the housing if the can is still holding on to the housing/rubber seal. (Can edge embedded in seal a long time).
