Echo 1 / A&K M249 SAW Gearbox Guide
 
I recently created a site for the Echo 1 and A&K M249 SAW, showing step by step photos regarding the disassembly, maintenance and re-assembly of the the SAW. I did not see any decent guides on the web to help those in need, so I decided to write one myself, taking the pics way back when I bought the gun, then finally getting around to creating a web doc for them and posted it. The link is shown below and it should be a good guide for beginners and veterans alike and I am posting it here for the benefit of our membership. Let me know if you have any questions or comments.

M249 SAW Gearbox Maintenance

+1 I think this should be made into a sticky

Locutus 06-25-2009 12:50 PM

Nice job NW! Stickied.

Vader 06-25-2009 05:52 PM

Excellent guide!

It's so nice to find one that shows the correct way to do things, and not using the jerry-rig method. Well done.

Why not :) ?

Yes it will. That is why the title is "Echo 1/A&K." Incidentally, this also applies to the UK Arms version, as well.

Great thread and great site.

Nice job NightWolf. It should be an instruction manual. Thanks

M249 SAW Gearbox Maintenance

UrbanMarine gave me this link, and with it I went from oh crap, that was $200!, to YES, it WORKS! and I got a 1911 in trade for my M249.

Thank you for creating this, sir.

Great right up, this is very useful.

Just wondering, why do the gears look so rusted?

NightWolf 07-05-2011 07:28 PM

They're not rusted...it's the color of the metal under a bright light, i.e. the camera. They are actually a bronze/steel color with the spur gear being more bronze and the others more steel in color. The gears themselves are a cheaper Chinese made steel.

nightwolf this guide has helped me so many times. thanks a lot for this!

Oh, okay then. That makes more sense. :D

I recently bought the A&K M249 from my friend who thought it was broken. I took it apart (including the gearbox) and realized that the middle gear had sheered its pin between the gear and the gearbox. The other gears are missing a few teeth. I might be able to get a new pin made but I would rather buy a whole new gear set, but I can't find them anywhere.

Does anybody know where I can buy a replacement set of gears for the A&K M249 SAW?
They are the exact same as the gears in the guide above.

(PS, the guide is incredibly helpful, thankyou!)

Darkstar 08-22-2011 03:44 PM

@ Tank - The 249's gearset is compatible with everything else. So any standard ratio gearset for an AEG will (should) work.

Tankperson 08-22-2011 07:56 PM

Would these work?

http://echo1usa.com/English/index.ph...lvi31g5p3tjh84

The only problem i see is that on the left-most gear there are six teeth in the middle section while mine only has five.

Also, I just realized I'm missing the Anti Reversal latch. I assume that interacts with the set of teeth I just mentioned. Will the gun work without the latch? If not, does Echo 1 sell them? (I couldn't seem to find one)

Italian 08-22-2011 08:00 PM

That gearset will work and yes, the ARL does interact with those 6 teeth.

You don't need the ARL for the gun to work, but it is a good idea to have one. Otherwise, your gears will spin backwards when ever you stop shooting and could mess with the motor. They're cheap anyway...

This one will work:

Tankperson 08-22-2011 08:24 PM

Thank you very much Darkstar and Italian, I've been looking forever for those pieces haha

Tankperson 08-22-2011 08:35 PM

One more thing, they sell those gears in a 13:1, 16:1, and 32:1 set. Would I benefit from buying the 32:1 over the 16:1 gear set or does it not matter?

Italian 08-22-2011 08:37 PM

32:1 are hi-torque gears and will give you a lower ROF. 13:1 and 16:1 are higher speed gearsets and will give you a higher ROF. I suggest getting either the 16:1 or 13:1.

Tankperson 08-22-2011 08:39 PM

Whoops, nevermind. The 32:1 is a different gearset and wouldn't work.

EDIT: Good advice too :D
