CA M15A4 not firing

[nwahs]

Hello, hope someone can help.I tried to remove the pistol grip by unscrewing the 2 little screws and the big button screw in the middle, under the pistol grip. Out comes the bottom cover. Upon seeing that I cannot remove the entire pistol grip, I try to screw everything back together only to find out now that the AEG cannot fire...i use a large battery and it works fine...when i squeeze the trigger nothing happens at all.....
Hope someone has any ideas on what might happen.
Just wondering is there a way the whole wiring can blow out or something like that? Like a fuse for a lamp or something? Can that happen in an AEG?
Thanks

The centre screw on the motor plate is not meant to be tightened all the way. You should NEVER touch that unless you have a motor height issue, which it sounds like you have now...

Basically, you've more than likely jammed the motor way to high into the mechbox and it's now jammed. try loosening that screw until it fires and turns smoothly..

Also make sure the metal disc is present if it has one (allen key screw) or it may not have one and just be a flathead screw.

CA Armalites don't have a metal disc for motor height adjustment. They have the large flat screw rather than the small TM-style allen screw + disc.

How can't you remove the pistol grip?

There are another 2 screws inside the pistol grip that are screwed into your mechbox.

Use a flashlight if you cannot see.. lol

As said, you set your motor height too high when you put it back on.

To take the grip off (i.e. if you want to change the grip to a different style):
1. Remove the two screws (not the center one) and remove the motor plate/heatsink/grip cap.
2. Gently remove the motor leads (usually red first then black)
3. Remove the motor (it should pull straight out...it might be a bit stuck, use pliers or and allen key to pop it out)
4. Remove the 2-4 screws at the bottom of the grip that screw it onto the mechbox.
5. The grip should pull straight down and off...don't yank it off or your motor connectors will catch and you'll break them.

To reassemble do the opposite.

Any time you change the gears, mechbox, grip or motor, you should readjust the motor height.

1. Screw the motor in all the way with the center screw/allen key (some are little allen screws, others are a bit screw)...just in, don't need to crush it in there (you've already done this).
2. Back the screw off a full turn.
3. Try a shot. (if it's still too tight and you hold the trigger down, you'll pop your fuse)
4. If it doesn't shoot go to 2, if it does continue
5. If it shoots but sounds "squealy"/harsh, continue backing off the screw 1/2 a turn. If it makes it worse, screw it in half a turn and continue.
6. Once it's shooting, continue adjusting the screw in smaller increments (i.e. 1/4 turn, and then just a little) until you get the quietest/deadest sound you can.
7. Fire the rifle on full auto for a short burst, then on semi for 3-4 shots (that will reset the piston)

* put a tiny drop of nail polish on the screw to hold it in place. It's common for a loose screw to back off and then you risk stripping your gears.

Best of luck,

Tys

wow thanks for all the help....yeah heard its something to do with the center screw being too tight or something like that...but Ill try to figure it out later...oh yeah one other thing.....this thing that is happening...its not like something really serious right? Its not necessary to get a replacement for anything? Just an adjustment of the screw?

[Styrak]

Sounds like it. Not a big issue. It was working before right?
