MP5 not firing?

I have her opened up in front of me nowSouthern Dandy wrote: »The motor pinion generally keeps the bevel to one side unless it was ridiculously over shimmed I doubt it is the problem. And like you said the aeg was firing fine until lately, and to my knowledge you did not re-shim it yourself no?. The bevel does not require too many shims in my opinion.
If your pinion is worn half way then it stands to reason it was either too high or too low, this can be adjusted via a grub screw normally beneath where the motor sits. But honestly, if you can not figure this I would take it to a store with a good tech and leave them have a nosey.
You are correct in thinking that I haven't messed around with the shimming, so I doubt that they're over shimmed.
I didn't adjust the grub screw either, but I'll get around to that once I put it together
I've already thought about that option, but a) moneys a bit tight at the moment , and b) I'm trying to expand my knowledge on my guns insides, so want to gain a little experience!
Thanks mate for your help

OK so lads, I think I've sourced my problem...
As I'm very new to this, I didn't fully understand how to connect the last gear to the piston, so just left it sitting outside of it!
As I don't know better, maybe that's what you're supposed to do?
Could someone please guide me in how to link the final gear to the piston? (I mean do I have to link the teeth together?)
Thanks in advance
Did you have a look on youtube for a tutorial?,there should be plenty.
Your sector gear (final gear) should be set at the 1 o clock ish position, basically you should see the little part that protrudes from the gear (not sure if it has a name), then you put you tappet plate behind the nob thingy, then insert your your spring and guide, make sure you anti reverse latch is properly set, parts are present etc, sorry for the dumbed down version but am far far too lazy to type a big post.
But have a good look on youtube for a version 2 gearbox disassembly/assembly guide.0 -
Yeah id say have a look on youtube and on other forums. i find that shaving off the first tooth of the piston helps you get a good angle of engagement on the piston. since deburca told me about it i have done some research on it and have done it to all my guns. try and look through the gaps in the gearbox and make sure that the sector gear line up with the teeth of the piston.if the gear engages the piston too far to the left or right try switching some shims around
good luck0 -

Just did, and found out that the anti reversal latch was causing all sorts of problems by popping up all the time, i think I just fixed it...
Now I can't get the upper receiver on :rolleyes:
Anyway, Ill improvise :P

It turned out to be the anti reversal latch!
My hands are killing me from pushing down on the spring :P

Its over... Its finally over!!!
After a trek and a half of messing around inside her, the gun is finally working properly, and by some miracle I managed to fix the semi auto issue it always had!
I'm thrilled with myself (a bit sad, I know :P ) , I did it without spending a single red cent
Thanks all for your help guys, this certainly took a big chunk out of my month 0 -

Once you do it once now you can do it anytime you want now eoghan
That was exactly why i didn't just pay a gun doctor to patch her up the second something went wrong!
I feel like a technological genius lol
(if only
)
I finally understand all these extra parts for sale :P
Thanks again for all your help lads, I really appreciate it 0 -

Or possibly wasn't sitting down on the sector gear properly? Think your onto something man 0 -
