This has been SUPER useful! Thank you so much!

Helps me a lot while im upgrading my AK first time, thanks :)

i really really appreciate your video, prob the best teching video i e ever seen

Thanks alot for makling this video, it really helped me out alot.

very nice directions!

So helpfull. Everyone else just says take this and that out. Put it back in like it was. They don't tell what the parts are or how they go in.

That was rellly good. Glad you guys did that it helpsa lot.

Excellent video!

Great tutorial !!!

Assemble on a magnet. Once the box is all together and some screws are in to keep it from flying apart you can crack it open and reach in with dental tools and reseat the ARL. You can also reallign the trigger too and push the gears around some.

If your trigger fell apart like mine did theres supposed to be a screw holding it to the gearbox housing that most manufacturers miss

I should've watched you before my spring went complunk and flew everywhere, haha.

Best to use a strong neodymium magnet on the outter shell to hold down all the gears/AR latch

Thank you now i now what I have to do if i am open my gun.

nice

Great video, best ive seen for taking apart the mechbox. A question if I may. I have an ICS SIG 551, which as you may know uses a modified V3 mechbox. The gun is completely stock and has only been skirmished once. After each shot, there is a metallic clunk. I have attempted to research this with little results, however from what I did find, it's to do with the bevel gear and the ARL. From watching other videos of ICS SIG's, its not a common issue. Have you any idea's for a fix?

once you remove the top plate use a vise grip or a clamp to hold the trigger in place coz that part is a pain to install

If the piston head isnt coming loose and you want to get the spring out without cutting the piston, you can pull the old spring out by force, ruining the spring but leaving the piston intact :D at least worked for me

Just one question.. what's the correct position of the antireversal and the sector gear before closing the gearbox? Thanks so much!!!

On the trigger, where does that small curly spring go and what is it's orientation? its the spring that gives resistance to the trigger.

Does anyone know if this works with LCT aks like the LCT AK74M? Oh. And this is so much easier than what I thought. Do I have to mess around with the gears if I’m JUST replacing the spring? Because I’d be doing this on a brand new gun.

when upgrading any AEG can I ONLY upgrade the spring? or will it put to much force on all the other parts?

can this guide be used for changing the spring in the Real Sword type 56-2's gearbox?

ok the top plate on the mechbox the bushings on it dot have shims right?only behind the gears is where shims go?

14:20. Did exactly that and the nozzle broke off and flew across the room. Why is that? Can that happen if the spring is too strong? I put m110 SHS spring in there, but could have sent me the wrong one or something, or I could have installed the nozzle wrong?

I put the anti-reversal latch in correctly but it seems to be jamming the gears when i go to test it, the gears move without it in in the right direction. I just can't seem to figure it out...

Do you need thread lock to put your new spring in? Please answer I really don't want to break my gun Thanks

Could you please tell me, why it is important to align the sector gear using the tapet plate notch on the gear as a reference point? So you can install the piston in freely afterwards? Or does it have more meaning to it? Cheers bro, nice video!

Could you please make a video showing how to change the spring on a umarex g36cv that would be amazing I don't want to damage the gearbox

I think setting the timing of the gears are not needed, as the everything should be auto aligned with one cycle of action of the gearbox.

how do you get the ant-reversal latch to not pop out during installation please respond and thank you

What is a good spring to upgrade with this gearbox? I have an ASG steyr aug and it shoots around 330 fps, just want to bump up around 400

is it possible to just change the spring without messing with the gears?

my tappet plate end is really high and is knocking the bushing off my gear...it isnt laying flat its almost bowed? do you what i should do?...sorry my explanation of the problem isnt to great

Mine sprung out before I had a chance to put the screwdriver in to prevent it so. and the Whole trigger mechanism came out, any suggestions?

What should I do if my v3 gearbox airpiston head is sluggish and doesn't fire 100% of the time?

What the hell is the mm of the bushing. I've been trying to find out for my cyma ak. I can't find it out anywhere. I lost one of mine when trying to put In a new springs and it shot all the gears and stuff around my room. I just couldn't find that one dumb bushing. It was so annoying and I've been trying to fix my ak47 that I've have dumbed so much money on for the last 6 months

Use the screwdriver to put the spring! Be careful man..

my piston head wont come off it just keeps twisting how do i get it off

i have no semi fire what idoin wrong ??:(

You don’t need to put thread lock of every fricking screw

lol sp 130 killing me

It's so easy "not"

No, that will not work. They are only $10
