Recently the spring that returns the sear on my Zero Trigger broke. This caused a small panic of "Oh great, 500+ rounds later and my $200 trigger is done." I decided that since I might have to send it off for repairs why not take a shot myself? To make a long story short I'm glad I decided to try it myself.
First thing you want to do is remove all the hex screws from one side of the plate. Gently and boy do I mean gently separate the two plates. Yous should be left with something similar to this, if the pillars or rings fall off don't worry I'll tell you where to put them back.
Go ahead and remove everything until your trigger looks like mine. Don't worry no small parts will fall out just pillars and rings.
Now slowly pull the sear assembly off the plate and set it right side up. Take a look at the picture and remove the ring and the pillars that are displayed in the picture.
The back section of the assembly should be like this with the pillar removed. Now remove the bottom pin, note that this pin is a different size so you need to keep it separate from the others. When you push this pin out the two plates should fall along with the spring.
Reassembly time. Grab the sear assembly and the first plate along with the special pillar.
Now the spring, then the last plate.
Now grab a ring and put it in between the plates and stick a pillar through them.
Ok before we starting putting things back together we need to add the rings that we can't put on if we assemble others things first.
Here's a key to help understand the picture.
Green = Ring
Red = Pillar
Yellow = The two pillars on the sear and the back of the sear assembly.
Gold = Trigger sear pillar.
Following the guide you should be able to get to this part fairly easily. Please note that when installing the spring guide look which way the notch is facing and that it sits on top of the rings. Also the two rings that are on the sear assembly.
Here you can see a final picture of assembly with all the springs attached to the personal pillars. This part gets pretty tricky since everything is under tension so taking your time is key here to not have everything explode on you. If you can get everything in place without holding it simply put the plate on top put a ton of pressure on it and move the pillars with a small screwdriver to align them to their holes.
If you anyone has any questions or if pictures expire let me know and I'll help and or update the pictures. This link will take you to the album for the guide that includes some more up close pictures for people having issues with the final assembly.
Parts for your LayLax/AA trigger can be purchased here. (Thanks to 1tonne for the link)
