but i will prevail


i never said anything about getting your friend to do her... lol. in that case spit roast!

but uh no, i lack experience with bad gun noises. i don't even know what that screw on the bottom does.

but by the sounds of your problem your mech box probably has to come out anyway. that's the easy part. you may be able to see whats up if you take it out and look in it without taking it apart.

Okay im really studying how mechboxes work, im actually getting a hardon for this stuff. This is an idea i had while chattign with my doc

Amazing KG3 says:
DOOD
Amazing KG3 says:
Gear Axel
Tristan says:
ya that could be fucked
Amazing KG3 says:
i think by pushing the motor to deep into the mechbox its offest the gears so that either the axel snapped or bushing came out and is obstructing the selctor
Tristan says:
exactl
Tristan says:
y
Amazing KG3 says:
also explains why it would whir, and no why it is jammed
Tristan says:
now you are thnking
Amazing KG3 says:
: D
Amazing KG3 says:
w00t
Tristan says:
but it could just be bent
Amazing KG3 says:
ill still replace it
Tristan says:
in any case new gears is the most likely part you will need
Tristan says:
well ya


Worse case scenario, cracked mechbox, but i highly doubt that.

that sick "whirrrrr" you described sounds to me like the motor is installed too deep. when you put the motor in did you run both red and black wires up the back of the motor, or one on each side? I did this once and the same thing happened (whoops, live and learn!) the wires need to both be run up the back of the pistol grip.
what kind of spring do you have installed?
what brand of gears?
check your air nozzle and see if it looks like its been hacked up

its all stock. And i do think the motor is up there to tight. I can see it being jammed but i know something busted in there. I heard a nasty noise.

Damage report is in, this is what i need

-New gear set
-New Spring (upgrade, not necessary)
-New 7mm busings
-New Bearings (Are these 7mm bushings?)
-New mechbox body pin
-Shims

Do i need CA specific parts? Any guidance would be appreciated.

official report:

1x shattered bushing
1x damaged bushing
1x bent mechbox pin
broken teeth on gears

what a mess, the gears were totally siezed. thats what caused the whir sound.... sounded like a duck actually. anyways, any parts should do. only thing that needs to be CA is the mechbox pin.

Any gearset from any company would do Depending on if u want to upgrade or not, now would be a good time
And your 7mm bushings/bearings are the same thing i believe since they should be steel, relatively inexpensive
New gearsets sometimes come with shims if not then buy a set which is about 10$

The gears would be the most expensive replacement, everything else should be about 20-30$ unless u get a very expensive spring
But i have no idea where u would get a CA pin, if any M4 pins work just get some KA ones off ehobby they work

ive got everything except for that friggin mechbox pin. I am told that CA needs a bigger pin as TM and ICS have smaller diameters. This is oversized, anyone kow if it will fit?

I recommend buying mostly systema, and replace your tappet plate while your in there, the CA ones are extremely prone to failure lately.
7mm bearings are good, 7mm bushings would also work as an alternative, its 6mm bearings you need to stay away from.
