JG Generation 4 Gearbox info

[Jason Bourne]

I have a JG Generation 4 Gearbox. When I pull the trigger, nothing happens. I have taken the whole gearbox apart, and cannot find anything terribly wrong. The only thing that I can see that is completely off, is that there is some black where the metal part pushed by the trigger slides into some time of coper pincers.

Is this what is causing my issues?

Try a different battery, inspect every bit of the wiring for flaws/lack of a connection, try a different motor, clean the trigger contacts, and make sure your trigger post isn't broken.

Remove the motor and connect it outside the gun, see if it spins.

If so, motor is either not strong enough or something is wrong in the mec box.

If not, get your multimeter out and find where the issue is. Start with the motor to see if you get a voltage differential there, move to the battery, then check the resistance on the wires between the battery/trigger/motor.

I just talked to the guys at AONW and figured out at least part of the problem...Thanks though. I had already tried all of the easy issues.

The guys at AONW and I figured it had to be the trigger post.... It is a $75 minimum fix....including shipping...

$75 for a trigger post fix -_-.. Did you mean $7.50? I could do a gearbox overhaul for $75 Not to put down AONW but damn.

Please post a picture of your gearbox if you can. It'd help a lot

I'll put up a pic in a few hours, I have a class starting soon.

It is $15 for shipping it there... not on the way back.
$40 for making the gun work on auto only
$20 for re-shimming it.

holy smokes, just buy a new trigger set, put it in yourself, buy a set of shims, and try it till it works. Spend some time on youtube watching how to video's, it's not that hard to fix. Then take the extra $50 you saved and buy more airsoft gear.

I am not sure, but I don't know that a trigger set will fix it..??

The trigger post is part of the gearbox shell, that's all that needs to be replaced... I guess the shell plus labor fees is decently reasonable at $75 considering it's probably the most time consuming part to replace because you have to really redo everything.

I don't know how to post pictures...

I just found a small square metal thing... I guess that is the trigger post. [/img]

They are already in the gearbox so all they'd have to do is remove the cutoff lever..

And easy fix to post: Drill where post was. Insert set screw.

I don't have any of those... But I put it on the COA website.

Thanks for all your help guys...It was the trigger post.

[Jason Bourne]

I got it fixed..., I drilled through the gearbox, but not all the way through the plastic plate on the other side.

I then took a nail and cut it to the right length and inserted it into the hole. I first secured it with glue, but that didn't hold very well, and it was a little wiggly, so I took it out and then used a cement putty....which I am not sure will hold it or not. I tried to push in as much as possible and build up around the peg as much as possible. I then put the whole thing back together and it is firing right now.... I just don't know if the peg will hold....
