I think my MP5 Is Screwed
 

Right now im pulling the trigger...it does it on both single shot and automatic..the gun is just like " screming" it wont shoot any pellets or anythign. whats wrong, could the gun be needed a battery charge?

maybe the motor? sounds like something may be broken/worn out... try taking it apart for inspection?

Its like the motore is whining...i took about 10 rounds this morning then it just started doing it

I just bought it and the guy said it was just upgraded and shit

that, is not always good, your battery may have been too powerful for your motor.. and that may or may not have caused internal damage... where did you say you got it from and what model and how much did you pay?

600 bucks for a brand new universal smart charger..battery..the the CA mp5a4 or something, i just asked him he sais the motor might not be makeing gontact with the gears so i have to re alighn in...im lookin at the motor right now in the hand grip i dont know how to move it up and down though .

nor do i, but in any electric powered weapon, the gears and internals are in constant motion, so you gotta be careful to never do anyhthing that may cause unneeded stress/strain on those parts, such as adding a over powered battery... as per your little gear re-aligning problem, i trust your gun came with a manual... being that classic army is a quality brand.. but nothing is perfect, least of all any airsoft mp5

im moving the two screws that cover the motor and its changeing noises everytime i tighten/loosen them

dude, i seriously hope you arent taking it apart and holding the trigger, thats a very good way to break it...

i figured it out..i have to realign the motor height cause when i pushed it up..it started shooting again but now i have to figure out how to keep it there

there is a screw in the botom of the grip plate, tighten that and shoot semi till the gun is shooting as quiet as possible again.

There should be a hex head set screw in ther center of the motor plate (on the bottom of the grip) and a flat round disc on the inside that sits between the bottom of the motor and the plate. If that screw is missing, you need to find a replacement as that is the only adjustment for the motor height,and if the disc is missing,you need to replace that as well as the set screw will sit on the main shaft of the motor and eventually damage it. Don't keep pulling the trigger while it's sitting too low as you are grinding the motor and bevel gear into dust.

The motor wont turn the gear now, could this be because my battery is to low, or because the motor is to high? Im charging the batter to full now..The battery was low i think when i got it cause it was brand new and he just put charge in it so i could fire a couple shots.

I had an issue similar to this, just make sure that screw on the bottom of the grip plate isnt to tight or to lose, theres some form of happy medium there. When I hate it to tight it wouldnt fire and just wine, when it was to loose it wouldnt do a thing.

The gun still wont work....i press the trigger it goes click and then when i let go of the trigger it clicks again...im gettin pissed i just bought this it shouldnt be doing this.

Iv had the battery charging for like 45 minutes now im sure its got atleast enough juice to turn the gears for about 30 seconds..something isnt right

just bought? as in, still eligible for refund?

Just making sure, what brand of BBs have you been using? You haven't somehow developed a jam, have you?

I dont think there is a jam, im useing metal tech .20 bb's..where would there be a jam?

when i pull the trigger, it goes "click" and when i let go of the trigger it will click...its either that, or i loosen the screw on the bottom by the motor and then the motor is to low and it will spin and like grind against stuff. Make the whining noise.

Stop messing with your motor height adjustment before you break something else. Sounds like your mechbox has seized up, but a number of things could cause that.

Try setting your hopup to zero and running the unjamming rod to check for barrel obstruction.

theres nothign in the barrel iv just checked it all. Im gonan talk to the guy tonight and see if he can get it all running for me.

The arrow indicates which direction to turn to add more hopup, turning in the opposite direction would decrease the hopup.

Just put the hop up to zero and nothign is in the barrel. Could the battery have anythign to do with this? not haveing enough power yet to turn the gears. but yet it turns the motor.

What size of battery...

The clicking could mean the motor is up to far, just back it out slowly shooting one semi shot at a time untill it fires, if it wails, tighten it up a bit more, if u cant get it to shoot, ur gears are jammed inside, or ur shimming is shit.

As I said, it sounds like your mechbox has seized up. If you haven't been able to resolve the problem by switching between semi and auto, you might need to have your mechbox opened to fix the problem.

I highly recommend against you doing it yourself.

Yea im not gonna do anythign inside myself...im going to charge the batter up full...try what renegade said and if that dont work im gonna take it somewhere. Are there any places in the durham region that i could take it to? Or somewhere close to get it fixed?.

and renegade i think he told me it was a 8.somethign volt battery. large battery.

8.4v, all airsoft batteries are a multiple of 1.2v, 7 cells makes 8.4v.

Yea thats it. but iv been taking it on and off of its charge over the hour so maybe i shoudl let it charge fully then try

The gears shouldnt be broken already. it doesnt look like its been through alot of use..he said hes never really used it and it was working perfectly yesturday and early today. the battery is new so do you think it will take more then an hour to charge?

I got this from a site sellin the same gun i have

Battery Charging Time: Charging time may vary because most of the batteries were tested. If the battery is strong, 1-2 hours. Weak, 3-4 hours. If the battery is dead, the initial charge is 12 hrs but do not exceed.

The sector gear i believe is probably broken, due to you fiddling.
Take it back to the guy or get a knowledgable guy to help you out before you do more damage.

How could it be broken though if it was doing it 2 minutes into fireing off a couple rounds..it cant be from me fiddling lol i think the battery if just dead..its a new battery and only got a little charge in it im gonan charge it for couple hours or so and see. That would only make sense

constantly charging from almost full doesn't exactly help your battery. when you were firing while adjusting the motor is what beazer means

playing around with your motor height and firing while your motor height is loose could have caused a number of problems to your gearbox. U could strip a gear in a could seconds let alone 2 minutes :)

Let us know how the charged battery goes, it sounds like your mechbox is seized with the piston fully back and it doesnt have enough juice to finish the cycle

sounds like a dead battery + motor screwed too hard.
45 mn may not be enough depending on what you charge it with.

how many mAh do you have in this battery?
how upgraded is it? (what spring precisely: it's the spring that kills the battery.If your spring is strong, no doubt the battery got tired.)

charge it for 3 hours, NO LESS.
test it.
if it works but screams, un-tighten the motor screw until it's smooth.


edit: the click-click thing I'm almost absoSlutely sure it's a dead battery:
enough power to 'jam' the gearbox, but not enough to crank the spring.

maybe you have a stripped gear, but it's not clear, so just charge and test again.

i think the piston is all the way back cause i was shooting with single shot and i would fire but didnt pull the trigger all the way 1 time. and the battery is low obviously..its still chargig so ill give it about 4 -6 hours

omg just do what people are saying, the piston will pop forward when you follow them

my gun made the same clicking noise... it was my battery. who did you buy it from??? website maby? also i dont think you can return it if it was brand new they shoot it at the store first just to make sure.

If you show up tomorow, I will give you a crash course on what fucks up your guns and how it works. Age verify u as well if u take the time to ask the right questions and listen. I can also take a look at the gun on field and see if I can get it working, or tell you what is fucked.

Theres no fuse between the battery/gun. I charged the battery for 4 hours..i plug it in the motor turns for about 3 seconds....slows down and stops....its supossoly a brand new battery. i dont know whats wrong.

Stop, put it down, refer to someone who knows what they are doing.

So yea i just threw in a batter pack from my rc car and the gun is shooting..its a 7.4 volt though only i beleive but its got the motor running. can i use this battery from now on? or should i get a new battery cause obviously it was just the battery. i think i blew the battery from taking it on and off charge.

Well if it's just the battery then that's fine. You should get an 8.4V battery though.

omg just leave it alone and let someone look at it its probably a below 20 dollar fix

I believe he just said it was the battery.

Get a new battery from one of the people here or one of the fine Canadian Retailers. I suggest 007 or A&A.

Or
http://www.cheapbatterypacks.com

They have awesome prices, and customizable packs.

or completely discharge then recharge it there isn't much u cant screw up if its not working

gun is fixed now..turns out i had to take the battey out of the stock and charge it right from the battery wire..not the wire that connects to the gun.....embarising.

? how could you get a male charger to connect to a male end from your gun?

Let me get this straight...you were detaching the battery and charging THE GUN? OMFG.

LOL, first the gun wasn't broken at all. And if you did had a manual you should have read and study it before messing with your Mp5 :smack:

Must be huge electrical current in the gun lol man, the motor must taking a lot of power juice...

Hehe, I had the same problem with my very first ICS MP5A4.

I shot full auto with a 8.4v 3000mah battery, and I killed all my gears after 10 rounds. At that time, I was still a nub, so I didn't know. I tried moving the motor up, and all it did was click. I moved it down a little, it screams like crazy.

Seriously...WTF.

Im still confused on how he could pull that off because unless the plugs are gay they cant connect

Gay plugs can legally connect in many countries such as Sweden, Canada, etc. and even in some US states. :D

I'm still shaking my head after rading all this. Lol

lmao i dont know what kinda plugs they were..no the battery works fine for the gun the gun is working perfectly to...the wire that connected to the gun..its like a skinny plastic connector..i duno what u call them...like..i would disconnect the stock from the gun..and plug all that right into the charger. but now i just take the battery out of the stock and charge it like that...if someone if still really confused and wants to understand i can take pics hah.

aha, ur telling me, I almost wish I could have heard all this yesterday at FR.. man, woulda been hard to keep a straight face.
aha, please I think we all would like to see..

You were plugging a trickle charger straight into the gun and hoped it would power it?

Honestly... do some more research before using your gun again.

Don't forget to charge your bbs for longer range.

no..you read it wrong..i said i pluged the wire that goes from the battery to the gun and pluged it into the charger...the wire that goes from battery to gun...went into the charge..

The wire that comes right out of my battery...plugs into another wire with a fuse in it..and then goes into the gun

So you unplugged the connector that hooks up to the mechbox, plugged the one going back into the stock into your charger? So yo uremoved the stock instead of the end cap? Even if that's what you did, it should still charge your battery though since it's going through the fuse to the battery.

I am le confused!

ITT tips on how to start an electrical fire in your home

You have 2 plugs in the gun or the battery? What's going on I'm confused..

I'm waiting for the 'reloading a magazine' thread.
