+1 on that one as well, I would like to know how this would be possible. :confused:

There are some springs with rounded bottoms instead of flat ones. (Stock CA springs for example). I have seen springs from PDI and KA that have rounded ends. If the spring guide is not of good quality(eg. plastic ones with a washer), the pressure of the piston being pulled back can actually cause the springs end to slip off the area with the ball bearings on the guide (dont know how this happens, but its possible from pressure). When this happens the piston cannot be fully pulled back and thus the sector gear cannot complete its cycle becuase the pistons last tooth or the teeth near it are holding the sector gear from moving.

The way i fixed it was I just put a spring with a flat end in the gun and it started to work without any jams.

I hope that helps. Weird things hapeen to AEG's like the back of a gearbox blowing off or a spring guide cracking, etc.

And illusion your right about the shim job. I forgot even at 50% or 99% resistance they can still move:P I just had times where 1x0.15shim actually made the gears not move at all.

and when are those phoenix gears going to be in stock at WGC, I wanna purchase a set just to see how they perform.

Okay, that makes sense. I thought you meant the spring slipped off the entire spring guide.

As for the Phoenix gears, I'll be butching a gearbox that has phoenix gears in it. I'll sell them for a pretty cheap price because one of the teeth on the spur gear magically disappeared. :P What sucks is that I've hardly ever used those gears and I've never heard it jam.

I wil losen the screws on the gear box and see what happens.
I have the TM parts still,and will use the softer spring.

lets do business when they are ready illusion:P

Well guys,I loosened the screws and tried to fire it,same thing.
The wiring got warm as bye passed the fuse.Do you think the
motor is messed up and drawing to much current but lacking
power operate under load.I am not up on electrical things.
I was wondering should I replace the motor ,or is there some-
thing else should check first?.

Anyone know where I can find a hi-torque motor for my tm?.
I went through the list of retailers above using their search
and found nothing on motors.:(

sytema makes one, try airsoftparts.ca

have you tried turning the gears just byitself without the spirng and guts..or tested the motor byitself to see if it turns or notice any weird sounds?

I'll try that,what I had done was loosen the screws and got the same thing.
I helped the tube to the rear to fire then felt the wires and very hot.

Well I put a lighter spring in,I still get the same resualts.
Everything moves smoothly without the spring.I am going
to see if I can get over to schwags and learn more about
this aeg

The wires get really hot under normal conditions too.

Yes,I kept blowing fuses,so I held the two brass clips together and
it got hot quickly,I think the motor may have a short and can't
handle a load.But I am only guessing now..

Well good news,I found the problem with my gun,ME. When I
put the two mech box halfs together,I failed to notice that the
plastic tube with the gear teeth on it sliped out of the groove
for it.How it did this before I took it apart to fix it is still a unknown.
I must have stared at it to hard the first time to see it.

I have a new question.If the gun fires nice without rounds,then sounds semi
rough with rounds and not fire the rounds all the time,would this mean something didn't get hooked up right?.I did a motor height check,that seems
good.The gun works great as long as there are no rounds in it.
