I made a mess when I was 8, soldering for the first time, and no adult help.
Still not nearly as bad as that.

I remember when I had my first M4 GBBR last year. I was trying to install my new Magpul trigger guard. Started punching out one of the pins out ... CLINK !

The lower body right underneath the trigger chipped off with the pin still in it. That's when I realised the pins were one-way pins.

OH GOD WHY ...

Do you have a desoldering pump or silimar tools? If not then getting the solder out would be a pain...

ok this is a new one to me..
we have all seen various axle damage, but how about this
note the "difference" in the axle Width
http://i152.photobucket.com/albums/s...ps1ccdba0e.jpg

note the NUMBER of missing teeth
http://i152.photobucket.com/albums/s...ps2a1e899a.jpg

note the AMOUNT of material on the shell
http://i152.photobucket.com/albums/s...ps684a2309.jpg

Note the UNUSUAL shape of the bevel and spur gear lower bearings
http://i152.photobucket.com/albums/s...ps95098224.jpg

note the LACK of the molded rings on the shell that is supposed to be around the spur and bevel gear bushings
http://i152.photobucket.com/albums/s...ps0a25e10e.jpg

Note the ONLY tooth i found in the box (its above the piston rails)
and the factory seal was intact..

aperantly it was dry fired ALOT, but that much damage??
Discuss.

Are those grooved steel bushings?

ScooterVauto March 5th, 2013 04:37

they look alot like modify dual oil channel bushings.

HKGhost March 5th, 2013 06:35

That's caused by bad shimming and having to turning up the motor height to compensate for it. Basically the bevel gear sat too high and so the motor had to be turned all the way up to engage the teeth, but it also pushed the gear up and out of place. Over time like this, the side pressure not only chewed up the axle but elongated the bushings. That's why you can see that the elongated bushings is inline where the motor is going up. I always tell people that you need to check the shimming when a new motor is installed, as not every motor are the same dimension. Everyone needs to recheck their shimming every time you change the pistol grip or motor cage, motor, gears, bushings/bearings and gearbox shell.

i have a set of new SRC bushings and they do have grooved oil channels.
so they are stock.

dry firing does nothing.
