And I CANNOT figure out how the stuff goes back in. I have pics of my old setup, but i seems that I cannot get the trigger spring in the FCG right. I know how the parts go in. Anyone have pics on line????

Thanks MUCH - I was missing the disconnector spring!

Problem: The disconnector STAYS ENGAGED when I pull the trigger - so it won't fire. Any suggestions? (Everything looks right).

What kind of FCG are you using and what are you putting it into?

I have a Century Yugo M70. I HAD the old Century kit with knobby disconnector, etc. Century sent me a new G2 Tapco kit. The disconnector keeps the hammer back and won't disengage. If I trip the disconnector by had, the hammer slips on to the trigger group catch and it all works, but I always must do it by hand.

Again Yugo M70 with G2 FCG.

Quoted:

From TAPCO site
G2 Fire Control Group Installation: why is this happening?

Please check your rifle for the following and do not use “live ammunition” until your firearm is functioning properly all of the time. Cycle the rifle without ammunition and check for all engagements.

Make sure that the Disconnector engages the Hammer when the Trigger is held back. Release the Trigger and make sure that it catches and engages the Hammer. Move the Safety up to the safe position and make sure that it properly engages the Trigger and will not allow the release of the Hammer when pulled (there should be virtually no movement of the trigger with the safety on). Now release the Safety and a gentle pull of the Trigger should release the Hammer. Do these steps several times to verify that all parts are installed and working properly.

“Why is this happening?”

Hammer not engaging
Disconnector not engaging
Appearance of “double firing”
Safety not working
Trigger will not go forward without manual assistance

What we have found are some simple things to overlook during installation that have caused these symptoms. These are things that are easy to do and will cause the above experience.

Hammer installed backwards (the hammer will go in backwards on most rifles; proper installation is required)

Hammer Spring legs are not resting properly on the back legs of the Trigger (make sure that each leg of the hammer spring, left & right, is hooked over the appropriate leg of the trigger)

Disconnector Spring damaged or missing (some surplus rifles have springs that are worn or bent; replacement required)

“No Fumble” trigger Sleeve not installed (this is the tube that comes with the G2 parts and assists you during assembly and gives proper spacing of the disconnector and trigger; installation is required. This part goes into the trigger hole and through the disconnector hole. This acts as a subassembly and contains all parts so that you can install the trigger pin after all parts are in the receiver.

Trying to install a “double hook trigger” in a receiver designed for “single hook”; look at your receiver where the trigger drops in, if there is only one slot on the left hand side at the front of the square opening, you should be using a single hook model.

Trigger Pin not seated completely. The hammer and trigger Pins must be seated completely and a retainer must be properly engaged with the groove of the pin.

“Single Hook” Trigger drags or hangs up on the front of the receiver opening. Lately, AK receivers have had a wide variety of tolerances on the trigger opening. Some manufacturers now have a larger opening, some have a radius in the front right corner, others have square cut out. Late model G2 Single Hook Triggers have been designed to accommodate all variances above. This was accomplished by removing material on the front right corner so that it would properly clear the varying openings of the receiver.

Trouble shoot the FCG.

Check to see if the FCG is hitting anywhere on the receiver. The front or rear edge of the trigger may be hitting the trigger cutout on the receiver. If so, use a small file on the receiver or trigger to clean the area up so it does not hit.

Also, what was wrong originally that Century sent you a new FCG?

It is the Tapco G2 FCG - the old one works OK. I had some trigger sticking issues orignally. I guess the Yugo is a little different.

Make sure your not installing the hammer backwards.

make sure you hammer spring is ontop of the legs on the trigger

I had checked everything, and it looked good by all the pics. BUT - the interrupter engaged the hammer when cocked and wouldn't let go when the trigger was pulled.

I reinstalled the OLD FCG, and voila - it works fine. I do know that the Yugo safety lever has the shepard's crrook on it - but that is the only difference I know of on the Yugo AK.
