M4A1 gearbox trouble

[MayhemXXXFrosty (AndrewMp5k)]

Ok, i have a problem here. I recieved my TM M4A1 this morning (around 12ish) and as soon as I got it, i started disassembling it so i could start upgrading the gearbox with with my upgraded Prometheus parts and put it in my Metal body (Parts MS120, hard piston, metal axel holl, and double torque gears). So i get down to the bottom reciever, stock pipe, grip, motor, gearbox. I can't seem to get the darn gearbox out though! I am pretty sure that I unscrewed and took out every allen wrench there was, but it won't budge! Any ideas?

And i cant seem to fit the battery I bought from Hadoken into my front assembly (9.6 1100MaH Ni-cad).

what you have to do, is there is a little pin abouve the trigger on the body, you have to push that out with a small allen wrench. you also have to take out the Mag release if you havn't allready. I dont know if you did or not but you have to take of the handle to. Unscrew all the screws on the bottom of the handle and pull of the bottom plate. Its really stiff and stuck in there so you have to almost pry it out. Then you unhook the motor wires by simply pulling them out. Take out the motor and if you look real close, you can see 2 screws inside the handle, you have to remove those and pull the handle off. After that, just wiggle the mechbox around and it will come out. I had the same problem as you did 2 nights ago

- trigger pin
- magazine catch

Both of those also need to be tacken out. Make sore you DO NOT I REPEAT DO NOT strip that magazine catch allen screw. You should also have taken off the lower hop up assembly.

Do you have the complete grip off?
- You need to unscrew the grip from the gearbox ;D

You allready said you have the stock pipe off and body bolts off correct?

You should be able to take out the gearbox now.

As for the battery
- You have the RIS unit correct? If so then that is going to be a really really tight fit. You will need to fiddle around with it a a lot, to get it in. Its probly going to be real tight, i'm just warning you on that.You may want to try sideways, turning the battery sidways, long ways, that might work.

- good luck, i know how big of a pain in the ass that whole process if and i wish you luck. ;D

- Oh one last thing, make sure the gun is shimmed properly. Take a hr shimming it if need be. If its not shimmed correctly you will have a never ending list of problem (fortunatly for me i don't know this from expierience). Make sure when you shim the gun you put the gearbox completly together(screw wise). Don't just trust your shimming w/o the gearbox screwed togther, not a good idea.

- one last thing- the hurricane metal body is not a quick tear down model. You need to mount the gearbox in the upper reciever along with the hop up unit. Thier is no way to field strip the gun. Yes, its a pain. ;D- just so you don't come back with a i broke my taps/cracked my body thread.

oh and about the game...
Yeah i wouldn't of come either. ;D
- thiers going to be another one next week sometime, i'll post in the shelby twp game thread - sorry for going off topic mods.

I didn't read tz's huge post so if he already said this pardon me. you said you had the "stock pipe" still on? that needs to come off too. as well as the mag release, pistol grip, and dont forget any pins or the feed nozzle.

[MayhemXXXFrosty (AndrewMp5k)]

stock pipes still on, do i need the gearbox out first, before that can be taken off? I did take the bottom off of the grip, but i didnt take the motor out yet. I didn't think the mag release needed to be taken out, even though I wouldhave to eventually take it out and into the metal body (Not a hurricane, its a G&P metal body. Only one that i liked they had in stock ). So now I'm going to try all of your guys suggestions and see what happens. If i successfully take out the gearbox and upgrade it I'll start taking pictures jsut in case I need some help alogn the way.

Also about the battery issue its the REGULAR front assembly, not an RIS kit or the SPR kit. Just the stock front assembly. I thought one of them went in the bottom and one in the top, but the top grip won't fit back on right. Then i tried fittling with both in the bottom, not good because the only way I can is to jam them in and jam it back on, but it looks and FEELs like the bottom grip will break right in half.

On a side note, I read someone posted WITH the stock plastic body, there was some if not a lot of barrel wobble, there is none on mine, maybe i got lucky ;D.

The battery is going to have a very tight fit, you will need to knock out the fuse assembly, if you have an m4 varient other then i belive a xm or m733. If you have a xm or m733 then you need to unlock the fuse holder from the rod. The battery is going to have a very very very tight fit. A suggestion is to take the wires from the battery and put them through the barrel and over the sights. So your battery can be hung from barrel, just saying this so you get an idea what i am talking about. Your upper battery will need to be the farthest away from the front sight end as possible. The fit is going to be very tight. Make sure all the wires are clear, when assembling the forgrip after you get this together. The forgrip is going to feel somewhat tight. I would suggest a quick wrap around of electrical type, if you are so worried. ;D

What does the fuse control do, I mean DO i need it or what?

<edit> Also you do mean the big black kinda thin square in teh front assembly right? Plus how would I connect the battery if I took it out.... I don't really see how unless i totally redo the wiring on it... <edit>

[tZ]

wow that sucks

You will need to rewire it if you have a fuse assembly, like the one on show here:



Rewiring isn't to hard, the hard part is finding a fuse holder. ;D

[MayhemXXXFrosty (AndrewMp5k)]

Wow, i gotta rewire this son of a b!tch! darn it, jsut my luck. Anyone wanna trade me batteries ?!

[tZ]

Just knocking out the fuse would be easy, if you don't care i your fuse is gone or not. You would just need to cut and sodder. ;D

- this is the reason i bought a m733 when making my gun. I knew that the fuse assmebly wasn't the same and hence easier to manipulate into using a nunchuck battery. ;D

[MayhemXXXFrosty (AndrewMp5k)]

This gun is throwing out more probs then I can handle for now, For now I'm trying to put it back into stock. Didnt touch the gearbox yet but the damn motor wont go all the way in. This project will have to wait for now... I'll resurface when I think I have EVERYTHING and I mean everything figured out.

[Gestapo]

email the mirracle worker, bill, from 21CA, he would deffinitly take a look at it and either tell you how to fix it, or do it yourself.

[MayhemXXXFrosty (AndrewMp5k)]

Ok, I've done it. I sucessfully put everything back together EXCEPT the motor ! I keep putting it in,but I kno that if I don't put it in right the motor will turn the gears backwards (causing jams) and if not far enough in then it won't work the gears. I push it in till it wont budge, and I mean WONT. But then i press the trigger and i just hear the motor, not any shooting. HELP?!

[tZ]

I push it in till it wont budge, and I mean WONT

This is NOT a good thing. You want the motor to be able to move freely upside down. You may need to fool around with the wires some. You motor needs to be able to move freely vertically.

Now this can be your problem or what i'm about to say now could be.
- motor adjustment vertical (allen screw)
- motor is backwards (red should be closest to trigger(+) side

First tho realign the motor. It is more then likly your main problem. The motor needs to be able to move up and down easily. ;D

Not to burst your bubble or kill your hopes any but i seriously doubt your going to be able to pull of a full gearbox, body and front set conversion, by yourself. If i were you(with your knowledge) i would STOP now. The last thing you want to do is break something.

- especially the gearbox. If you don't feel confident and know what you are doing/never done it before you going to end up screwing yourself and your gun.
- just ask gastopo(sp).

[MayhemXXXFrosty (AndrewMp5k)]

Well thats what I was going to do, i dont have enoguh experience t odo it myself but me and a friend were gonna work ong it together LATER. I fixed the motor before you posted ;D, luck was on my side. I'm about as sharp as a baseball. That's why I used stupid text speak. anyways and i need a second hand with the gearbox anyways. Plus his is upgraded already and he did it himself 2.
