Help! Gearbox won't turn!

Sorry if this is wasting your time, but I did not really see an answer to the correct wiring question. Above, you state that the motor "spun freely" but I never saw you state that you made sure of the polarity of the wiring. I just skimmed the thread, but never noticed this. The motor will spin freely, but backwards if the polarity is reversed. The anti-reversal latch will prevent anything from turning and the gearbox will appear "locked".

Ensure your motor's polarity before you tear down too much.

Yes, I made sure the polarity was correct. Which way should a motor spin normally?

I would question whether your polarity is indeed correct or not. The anti-reversal latch prevents the gears from unwinding in reverse when you take your finger off the trigger and the spring is 1/2 way compressed. IF your polarity is backwards, the motor will not turn since it is trying to turn the gears the wrong way and is thus impeded by the anti-reversal latch.

1. Try reversing the motor leads , "just for fun" and give it a quick test.
   
   Failing that,
   
2. Something is obviously stuck in your gearbox. You may have to take it apart. WARNING! Don’t do this if you are not mechanically minded, or you will end up like NoobLord.
   
3. If you cant do that, enlist the help of someone more knowledgeable. Take it to a more experienced player and see if they can help you
   
4. Final option: Get the help of a professional GunDoctor

Yup, you'll need to disassemble your mechbox. It would assist us if you'd fill in your location information.

Ok, so I can spin the bevel gear now and now the nozzle also moves now. Now I'm charging my battery again and later on I will test it one last time before I open the gearbox. Otherwise, thanks for all the help that I've received!
