This may be why your motors have been burning out.

Holy crap, systema. Nice one.

it even says in the instruction, that the part is for gen 3 not current max models, and is not neccissary. i was pretty adiment bout installing it, but got lazy and didnt install it in the end thanks to my bud swatt 6-4's convincing, phew lol.

HA!

I had this exact same problem when I first built my chalange kit, mad max tought that might of benn the problem and sure enough that was it.

I'm just happy stokes told me about it before I squeezed a few off.

Scary little thing , that bearing is.

I am so smart SMRT lol.

The stupid thing is they are still installing it on factory QC'D guns... freaking dumbasses. I wonder what they will do to burnt out motors that was caused by the small piece of crap bearing.

both the pre-built 08's I got in had the ball installed from the factory

My 07 had it after 6 months of playing,Yikes! But never had any problems yet though.

Link doesnt work...

Fuck you videotron for this shitty internet that cost me almost $200 a month.

I think the PTW forums might be the problem. The link is not working for me either but I cant get onto the PTW forums at all.

K thanks.

Bah! That forum hasn't been working all afternoon for me.

I saw the article earlier.
It basically issued out a warning about the ball bearing that pushes against the motors armature, which leads to burned out motors. If your gun comes with a non-adjustable motor, you're NOT suppose to use the ball bearing, even though it still comes with SCKs.

There is an on-going issue because some Systema factory assembled guns came with the bearing installed and caused some motors to fry prematurely. Systema USA is awaiting response from Systema Japan as to WHY the bearings are still being installed, and whether users with prematurely damaged motors will be compensated.

I received my factory assembled M4A1 MAX July of 2007 on a preorder from 007airsoft. How do I know if the motor it came with is adjustable or not? It came with the ball bearing installed. Since day one, I have found the action to be a bit on the noisy/"grindy" side. I never minded it too much, since the action is so fast that it doesn't really drag on. To me, it always sounded like how a regular AEG sounds with the motor adjusted on the "too tight" side.
Thankfully, I've put less than 2000 rounds in the gun so far - in the event my ball bearing is incorrectly installed, damage is minimal.

Not just the ball bearing. I wouldnt install the set screw either. Whats the point. I noticed from the power of the magnets in the motor, when I fired the gun the set screw would spin and tighten in the grip. If you plan on installing the set screw I would use red locktight and give it time to dry.

PTW forums are up and running now and the link is working.
