NaokiS Posted October 17, 2012 Posted October 17, 2012 Ok, so I bought 2 rifles second hand of someone local for a good price, but one was dissambeled. Anyway, I know how the dissambeled one goes back together and reassembled it, but I left the gearbox out since I knew it was faulty. After diagnosis I realized a gear was worn down too much and so I tried to find a replacement or ways of fixing it, in the end I gave up and tried to find the gearbox unit to see if it was worth replacing or buying a new gun. The gun in question is a JG-139, and while I believe it to be made by Jing Gong, I can't find much, if any, reference to it. I found the gearbox here, but for $35 dollars I can't say it's worth it, especially since it needs importing. But now I'm at a loss, I can't figure out who makes this gear box, what model it is or where to buy one. If anyone can help this newb, I'd really appreciate it, since I have to call it quits after search for a good few hours without any clue. I have these photos if they help. Thanks, Naoki
RR01 Posted October 17, 2012 Posted October 17, 2012 I'm afraid that's one of the problems of buying the cheap Two Tones. I've never seen spares for those on any of the usual Airsoft retailer websites, either here or overseas. You would be better chucking those away and waiting to buy either a higher spec two tone with a proper metal gearbox, or getting your skirmish site membership sorted (if you're over 18) and getting a proper RIF.
Grounded_Pilot Posted October 17, 2012 Posted October 17, 2012 Looks very similar to an AEP gearbox. Or that used in an Uzi... Personally, I think it is a custom made gearbox for the gun.

Hmm, shame since I don't want to throw it away seeing as it has its box and ain't in bad con, but then it'd be worthwhile getting a new one I guess. Any recommendations, preferably same design and auto?
Johnno Posted October 17, 2012 Posted October 17, 2012 G & Gs aren't too bad for very little money, you can get a 2 tone with metal V2 Gearbox and blowback action for £160 ish new or £100 2nd hand.Very easy to customise/upgrade as most TM etc pasrt fit straight on :-) I have to agree that the plastic Gearbox you appear to have was designed to last about 5 minutes and even a new one would only be fit for the Bin :-(

Sacarathe Posted January 30, 2016 Posted January 30, 2016 Ya I know.just wanted help NaokiS Member Since 17 Oct 2012Offline Last Active Oct 18 2012 12:54 PM Well, next time check if the person you're asking the question of has been here recently, and then if the thread is a year old, pm them.
Supporters Samurai Posted February 1, 2016 Supporters Posted February 1, 2016 But the answer is the same. Throw this away, get an AEG. LPEGs are not suitable for airsoft.
Root Admin proffrink Posted February 1, 2016 Root Admin Posted February 1, 2016 Also man, if you just bought that gun and it's not working then send it back. Don't disassemble it and void the warranty.
Mmma Posted February 1, 2016 Posted February 1, 2016 I just bought it and it is working Only wanted to know how to fix it because a worn plastic gear is a common problem It the best gun I can get in Egypt till now There is no airsoft dealers in Egypt proffrink 1

Use it while it still works, then import a proper AEG if you can.
