Hi.
I've had this happen frequently. Simply cut a shim of "Scotch" adhesive tape and wrap it around the gear shaft for about two layers. Trim flush, and try the tubing again.
It sounds like the keyboard just needs cleaning. It's been described here: take a piece of fine sandpaper or "crocus cloth", cut a thin strip, and while pushing down on the flexible metal to make contact with the circuit board, pull the sandpaper out. Turn it over and repeat. Use a VERY fine sandpaper, and repeat a few times on each key. Should clean the contacts right up.
Let us know if these don't do the trick, and if they do!
Michael
