G&G Ver2 gearbox problems

[SQUID_MAN_HAM]

Hi all, Im having some issues with the G&G version 2 gearbox and I have no idea what is wrong with it.

I first try it withought the piston or cylinder inside and run it with just the gears in and it works correctly but when I add the upper gearbox sections it manages to wind the piston back a little way, then just produces a screaming noise.

Any ideas?

What have you done to it previously?

I take it you didn't just remove parts and run it for fun?

No, i was curious as to why the fps was so low at around 250 so i took it apart to find the piston head smashed to pieces. so i cleaned it out and put a new one in and now this has happened. slight update, i think it was the motor height that was causing it to screech but now it just clicks when you pull the trigger.

Stop pulling the trigger, you'll blow a fuse or worse!

Bring the motor height down a few turns, then work your way up half a turn at a time.

It is better to screech a little than be stuck basically.

Make sure the battery is full charged too.

ok tried this, just a high pitched screech and battery has just come of charge

Re: G&G Ver2 gearbox problems

I'd have it apart again, look for wear on the piston teeth or debris from the old piston head rattling around!

Re: G&G Ver2 gearbox problems

if it is screeching then there is deffinatly some dirt or previous broken parts still inside

as jag said , take the gear box apart and clean it ALL remove the grease from all the gears etc check the teeth are all correct on each gear as the sector gears inner set of teeth have a tendansy to break

also check the bearings and bushings to see if they have not imploded ..
if any parts are broke , replace them with the relevant V2 components

Re: G&G Ver2 gearbox problems

Yeah, i have already done this and tested it with just the gears inside and it runs perfectly, its only when i put in the piston and spring parts that it racks back once and then just starts screeching.

Can you get some good pictures uploaded?

Re: G&G Ver2 gearbox problems

have you checked all the teeth on the gears to see if they are all intact ??

and check the pinion gear on the motor to check condition

Re: G&G Ver2 gearbox problems

other things to look at ,

With the shell closed move the piston back and too to make sure its running fine on the guides and not snagged on the rear cut out

Did you replace all of the piston or just the head ? if it was the full piston what make/type was it ?

He replaced the piston head with a JG one , It is still the stock piston
