Echo 1 Gearbox Help

Recommended Posts

hello. I need some help figuring out my echo 1 m4 gearbox. basically I took it apart because the cylinder kept jamming and I couldn't get it unjammed. well now I have it apart and im not quite sure why it was jamming, I was assuming something was stripped or bent but that doesn't seem to be the case. either way im not sure how to reset the gear positions because when I opened up the two halves, the spring unjammed and shot everything out and messed em up. I know the general placement of them but I don't know how to set the half gear and the cylinder back to normal. if anyone could point me to a picture guide or explain in somewhat decent detail, it would be really helpful.

 

[edit] whoops almost forgot... some of the important parts you might need to know:

Systema 6mm metal bushings

 

Systema M120

 

Systema duracon piston head

 

Echo 1 cylinder set with polycarbonate piston

 

Echo 1 spring guide with bearing

 

Tokyo Marui EG1000

 

thanks,

D

This site should have everything you need. If this doesn't answer your question, PM me and I will be glad to help.

EDIT: Whoa sorry, I didn't notice that you said Echo 1 M4. For some reason I was thinking G36. Hmm... Here is the new link

That's the wrong link. M4s have V2 gearboxes. Look for the V2 spring upgrade video.

 

Great site, helped me with my gearbox. (my G36 gearbox was a pain!! I spent like 6-8 hours trying to get it back together. I eventually just took it in. I think my gearbox was just funky. The tappet plate was making the gears imitate the leaning tower of Pisa....)

got it working somehow. just if you go on auto and it doesn't finish a full rotation it will jam and the only way to fix it is to push back the piston with a screwdriver from the side and press the trigger. would that mean the motor is getting worn out and cant 'turn it over'?
