G&G Mechbox trigger contact spring and other questions
 

Hi guys,

Just wanted to share some gearbox exploration I'm doing and ask a question or two. I've been setting aside some time lately to explore a G&G gearbox to familiarize myself with the internals. It's G&G's GR16 gearbox, and is what is installed in AEGs sold as the "SOCOM Gear PWS Diablo".

Here's a shot of the inside of the mechbox:

A while back I posted about having trouble with the trigger action and it staying in full-auto even after releasing the trigger, sometimes even in semi. I opened the gearbox today and discovered very tiny pieces of a broken spring throughout the gearbox, some lodged into grease near the motor's gear, others closer to the trigger assembly.

When I inspected the spring which keeps the contacts apart, I discovered it was barely holding on by a thread and only had a half-circle of wire remaining (instead of the usual loop):

Anyone know the proper name for a spring like the above? I'd like to pop in a new one and I need to know what to search for.

UPDATE: Here's a package of stuff that appears to have the necessary spring. http://www.airsoftparts.ca/store2/in...roducts_id=966

Here's the stock motor:

I'm not very pleased with the sound of this motor and like the sound of my G&P's motor better. If I was interested in trying out a different motor in this thing for the heck of it, how do I go about selecting one? I've been looking at the range of G&P motors on airsoftparts.ca. Budget-wise, I'm comfortable with whatever, but I'd like to match the appropriate motor to this gear set and spring. I'm not 100% sure which spring is in here, but the gun shoots about 360fps (which I'm happy with) if that helps narrow it down.

Thanks

Most likely it is sold as a gearbox spring set, such as this one :

It is the smallest spring, the other one being for the tappet plate.

It'll be in a systema spring set, and if a spring failed, it's most likely your anti-reversal latch spring
Anything from G&P M120 and above will work for you, the M120 can pull 400fps no problem, but the M140 is higher quality.

Update:

Thanks for your tips guys.

I rebuilt my Diablo today with springs from the above spring set (anti-reversal latch spring, tappet spring, and that pesky trigger spring) and my firing issue seems to be gone now. I also threw in the G&P motor, a fresh piston + head, and a sorbo pad. Cleaned, re-greased, runs very smoothly now.
