From your post I assume this is a used scope. If it was purchased as "new" and had worn gears i would send it back to the vendor immediately for replacement or refund. The worn or damaged gears could have come from using a badly unbalanced scope with the clutches set too loosely, which corresponds a bit with your description. The other possibility is forcing movement by hand with the clutches engaged thereby "stripping" the plastic gears which can easily damage them; a sure sign of mistreating the instrument. To properly fix the issue the gears should be replaced, preferably with brass gears. Since this will be next to impossible by Christmas, the best you will be able to do is to clean up the gears as best you can with something like a fingernail file or emory board, thoroughly clean up everything and relubricate with a small amount of lithium grease. Do not get grease on the clutches! When using the scope make sure the clutches are tight so there is no slippage when the motors are running. also, make sure the scope is properly balanced so there is minimal strain on the gears. Good luck...
