1) When opening the gearbox, flip the gearbox so that you see the 3 bearings clearly. You want the mode selector on the table, and not facing up. It will also be easier to put the case back together with the side with the selector switch down on the table.
2) a little dab of crazy glue on the trigger spring (where the spring slots into the hole on the trigger, can make it easier to NOT lose that spring).
3) a little dab of crazy clue on the anti reversal latch spring - will really, really make it much easier to get that latch and spring positioned. to make sure you do not glue this item in place - first remove it from the gearbox, and set aside. Put a dab onto it, and then let it dry thoroughly. As Specialist rightly points out - you do NOT want to glue your ARL to the gun itself.
4) When putting the backlash catch in, remove the main gear first. Once the backlash catch is in place - you can put the main gear back in.
5) when closing the case - make sure that the register marks on the piston cylinder are seated into the slots on the case. they will also slot into the slots on the other half of the case. If you find that when you are trying to put the case back together, and it rocks back and forth, and won't shut - this is your problem.
6) at the front of the cylinder - there is a little nozzle (air nozzle) with a plastic tube on it that slides back and forth. This needs to fit onto the pull back arm (tappet plate). if not - you will find that when you attempt to fire your gun, you will dry fire, and then double fire two bb's.
I hope this helps others - as I learned the "hard" way during re-assembly and dissassembly of my gearboxes many times in the last several days.
