R.O.B. the robot repair??

[GreatBazunka]

If any one has any advice please let me know. I just got a ROB and it will go left right and open close but not up and down. I felt adventurous so i opened him up and commenced with surgery. All of the gears fell out and what looked like a sensor that rides along the center column to tell when he has moved one notch. Now after hours of messing around inside i finally got him back together but he still will not go up and down. It sounds like when he is trying to go up and down there is a gear that is clattering around inside. Im pretty sure i got everything back together right. I dont know what i am doing wrong. Maybe i have the motors on the wrong sides. If anyone has any pics or tips on the correct configuration it would be greatly appriciated. Thanks.

Not sure if this will help but I just googled your problem and got this.

Thanks< i have seen that site but it didnt seem to give me enough detail. I just want to be sure that i have everything in the right place. That guy just showed where to glue the gears which i found you shoulldnt do because all you have to do in his situation is removed the gear and locking washer and replace it. I noticed that same problem when i got inside my rob.
