If you need to put something back together exactly as it came apart, take digital pictures, ALOT of digital pictures.

Also, the drill motors are not that hard to put back together...just set aside about 30 mins per motor and take your time. I had no trouble putting one back together after it rolled off the table once we took it out of our kit. Spur gears were everywhere! Just remember to take you time putting it back together, and test it OFF the robot! Try to backdrive the gearbox, on or off the motor, with the pins removed you should be able to backdrive the gearbox. Be careful the first time you test with power apply power gently. When you test, you wan to have it running at free load. Good luck, if you're in the same neighborhood and need some help look us up, we would be happy to remove the pins and put it back together again.

Good luck
