Ok, I took a few minutes to pull the side panels off and also was able to pull off a couple of other pieces to access the gear box. I moved the gears and everything seemed to move ok and the cable from the battery box to the motor was not stuck in anything. With it still apart I moved the switch on the battery box and it started to move the gears. Now you would usually move the switch to the far left or right but if you move it slightly back towards the off position it works so I am thinking there is something wrong with the switch in the battery box. So it is working now and if I want to show it to anyone I just have to remember to not move the switch all the way. Thanks to all that had suggestions.

Once I get a few minutes to pull the side panels apart it will give me a better idea as to what is going on. As for the motor, it seems like it is doing nothing. When I turn on the battery box none of the gears in the gearbox rotate. I know is worked before but this is confusing. And if the wire got disconnected from the motor i'd like to know how because it is down in there.

So basically if I pull the side panels off on the side opposite of the operators cab I should be able to see the motor right??

Greetings, I am a "newbie" here so if this is not proper please let me know. I have a 42042 crawler crane and am having trouble with the motor working. The uni sits off of the floor on a shelf about 6 feet high and I don't mess with it much but the other day I took it to a Veterans Day brunch (I replaced the claw with a small US flag) and I could not get the motor to kick over. I know it is buried indite and is really inaccessible so I put in a fresh set of batteries and get a green light on the it but the motor still does not move. I also moved the clutches that operate the different functions to no avail. Also to note : the big gear box does not move at all.I contacted Lego directly to see if they have any ideas before I have to tear it apart. Any one out there have any ideas??
