were bbs coming out of it when he tried to fire it?

you did adjust the motor hieght?

Sha Do · January 12th, 2010, 22:53

No BBs.....and I assume that you can still hear the gears cycling, but there is not the accompanying thud at the end of the cycle??
Odds are that you have probably stripped the piston, or the bevel (or pinion) gear.

Make sure he's doing it right if he doesn't know much because if the motor is not fully engaging the gears, it would sound like that.

I was hoping if he didn't shoot too much that may not happen.

poor lil piston.

the AEG was brand new too.

LOL..."odds are", but not necessarily is the problem.....it could be a couple or any number of things.
Mack has been around for a couple of years, and I'd assume that he (or his friend), would know how to adjust motor height....though if he's never had to do it before...

As for the gun being new, anything is still possible. Odds are highly against it, but there is no such thing as flawless quality just because it's new.

I hear ya man, I fixed my share of BNIB AEG's over the years.

If the "ceased firing" can interpreted as it stopped firing BBs but the mech box continues to cycle - or - as the mech box has seized. Hopefully the mech box is not seized, as this could mean any number of internal problems ranging from a stripped piston to broken teeth on gears. It's the drilling sound he mentions that leads me to believe that the piston is the problem.

Best of luck,

alrighty... thanks for the repost mack... but this is the situation:

Brand new gun - fired off a few hundred rounds... just playing around... gun stopped firing but continued to make the noise of a dry fire... so no ammo (you probably knew that but w.e im new).... so i figured its just the mag to wind up... did that nothing.. still a dry fire; pulled the trigger to try it after winding the bottom of the mag... the dry fire continued for 4 pulses... then nothing but a drilling noise.

Now; as for the bottom of the grip as to where the motor should be adjusted according for height.. the allen key spot.. does not exist.. there are 4 wholes.. 3 of which are filled in with 2 small screws.. and 1 larger screw... the 4th whole is the designated whole for the allen key i would assume... if thats the case i have cycled through several different sizes for the keys... all of which have not been able to bite the sides of where to turn/grip.

If you need any more info please lemme know.... Thanks guys; appreciate the help

Moose29 · January 13th, 2010, 13:24

UPDATE: so my scope has come in today.... thankfully it has the proper allen key to fit into the botton of grip where people have been telling me to raise the motor... heres what happens:

I start to tighten the motor.. assuming its being raised, and the drilling noise becomes more of a high pitch sound... i lower it back down to the original standing and its the moderate drilling noise... i lower the motor some more... and it becomes a more harsh sounding drill.. like its catching some sides.. but the gun still does not give me the same dry fire sound as it used to... any ideas now?

Thanks, still appreciating the help.

are you sure you're turning enough? The motor height adjustment screw is about 8 or 9 threads long, which means you'll have about 4 or 5 full 360 degree rotations from max to min. height. So if the motor is at min, a quarter or half turn isn't going to do anything.

if the motor is hitting a high pitched noise... too far?

chaosnemesis · January 13th, 2010, 16:10

so it sounds like you've stripped a piston.
When the motor is off of the bevel gear, you'll hear a quiet "whir" because there is no load and only the motor is spinning.
As you tighten the adjustment screw the pinion gear will start to make contact and a more audible grinding noise will happen but it's not enough contact to start cycling the piston.
Tighten further and the rest of the gears (spur and sector) will spin cycling the piston, tappet etc.
Tighten even furthur and you'll have jammed the motor too far up and it won't spin at all giving you a high pitched squeel.

It sounds like the gears are spinning but, because there are no teeth on the piston (or one of the gears but it's more likely the piston)all you hear is the "whir" and no cycling. Don't be too bummed out it'll happen to the best of them and the part is only about 15 bucks.

I'd highly recommend taking her to a gun doc or if you are inclinned to diy then check out mechbox.com

Sounds like a stripped piston or bevel gear slipping.

Kos-Mos · January 13th, 2010, 19:07

Here is my diag:

You got a bad jam in auto.

The piston failed to return fully forward before the gears catch it again (thus the "poshhhh" sounds.

This damaged both the piston and gears, and probably the hop-up rubber and "maybe" tappet plate.

No magic trick, you have to open her up.

Allen key size for motor adjustment is 1.5mm metric. a 1/16" is too large and won't fit in the grub screw. In G36s, you can't back the motor far back enough to completely free it from the gears because of the motor cage.
