Okay it took a while for the bits and pieces to come in but I think we have what would we need to fix these punks. Lets go through our list.
1.Torx bit screw driver
2. small philips screw driver.
3. hammer and rod (knocking loose the pin)
4. nine ball bushings.
5. nine ball piston.
6. Dremel
7. Michael Jackson Bad album vinyl LP. ( Billy Joel will work to)
Now lets start. First get that hammer or smashy thingy and rod to knock the pin out of the body. This will be about the only thing holding the upper receiver to the lower receiver.
You should be able to slide the upper receiver forward with nothing attached. The fire selector will fall right off so be careful to not loose it. because I did.
Now there unscrew the the plastic what you ma call it covering the novel from the receiver.There should only be on screw holding it in.
Once you got that piece off you can slide the gear box out and disconnect the wires from the handle.
There we go that was easy. Now lets get frustrated as hell and open up the gearbox. There will be only 4 screws holding the puppy together. This is where the torx bit comes in handy.
Be sure to member where everything went or else your gonna have a frustrating time. One thing you might noticed is that these AEP boxes have 4 gears rather than 3. So don't forget that 4th gear lol. cause I did. Now after investigating every piece I found the problem.
The piston broke off a piece holding the shiny metal bit in. Luckily replacing this requires no cutting or shaving. Simply unscrew the head and screw it into the new piston. Also if you haven't flipped the record now will be a good time to do so.
About the bushings I will I could say the same, so I hope you got your dremel charged.
Get out a dremel bit that can fit in the bushing hole and began shaving it down by running the bit around the hole in a steady motion going round and round. After a few seconds of shaving try fitting the bushing. If you are able to add all 8 bushings that congrats you have 8x more patience then I do.
Putting this back together should be easier than a normal gearbox since the spring has a lot less tension then an aeg. GL to yah and dont wreck your gun in the proccess. This has been another half assed repair guide. (now 25% less ass!!)
