MAK90 / AK-47 Disconnector Issue

[isurvival]

Hello,

I bought a MAK90 and the hammer rides the bolt down after firing so there is no trigger reset. It will fire once and reload but nothing else unless you manually cycle the action.

It appears that the disconnector is not engaging the hammer at all. If I hold the trigger back and push the hammer back it just slides between the disconnector and trigger. Almost like the hammer is too short to fully reach it. If I release the trigger it will catch. I have attached a photo. Any help is appreciated. I am guessing someone in the past has "worked" on it.... new member but long time reader. Great information here!

That's not the original fcg on the Mak.
The disconnector looks like it has shims on both sides and is sitting too far back for the hook to engage. Is the spring in there for the disconnector? Should be a small coil spring in the tail where the steps are. I would replace that fcg with a surplus double hook fcg. Yugoslavian or Bulgarian should work fine

Thank you Nacho Man! I will try to locate the correct parts. So far I only see that the replacement FCG is discontinued.

No problem. You can check by pulling the trigger, ease the hammer down so it doesn't slap the center support bar. Hold the trigger back and push the hammer to cock it to see the disconnector engagement. The disconnector should pivot if it's under spring tension and snap on to the back of the hammer and hold it till you release the trigger.

Tried that. If the trigger is held back the disconnector will not catch the hammer. It barely touches it but not near enough to catch. It just slides between the disconnector and trigger catch

 

[Nacho Man]

Is there enough clearance on the safety bar for the tail of the disconnector. It looks like the disconnector is sitting too far back, some of those US made triggers had a sleeve in the hole. The trigger actually looks original but the disconnector and hammer are definitely not Chinese

Just to be sure, is the disconnector spring present?

The line going through the middle of the disconnecter looks like it's made out of cast metal. I can't find my original Mak trigger parts to compare. But I dont think the disconnecter looked like that. Somebody correct me if I'm wrong.
I would try replacing the entire fire control group

That's definitely not a Chinese fcg.
The hammer should have a purple hue and the disconnector is machined with polished blue flat on the front. The trigger might possibly be original.

Ok. Found my Mak FCG. The disconnecter looks machined to me.

Old rusty tapco disconnecter that shows similar cast lines. I think maybe your disconnecter is a aftermarket replacement. And is messing with the other parts.

The guts on my Mak with an ALG trigger group. Your pic looks like a way bigger gap between disconnecter and hammer then on mine. Hammer looks funny too.

vzenmn, I see see a coil type spring just under the twisted hammer spring? I don't think I have that. Am I missing something? Thank you!

At 6:19 he shows the disconnector, and the fairly >> concealed spring << placed into position etc.
Maybe somebody will benefit from this?

As a sidenote, getting rid of the shepherd's hook and installing a "pin retainer Plate" is ....Also...really easy (this was my first attempt changing any type of internal component--on any gun).
Never again bother with the diabolical "shepherds hook".

This?

No.
That is an ALG trigger group. They have a much shorter and lighter trigger travel then a stock AK trigger. That spring is what they included if you want to increase the trigger pull weight.

I posted that picture to show you the Hammer on your Mak doesn't look close enough to connect with the disconnecter.

Your pic. Notice the gap between hammer and disconnect.

My pic. Notice hammer and disconnect are closer together.View attachment 967753
I may be wrong. And if so somebody correct me. But I would just buy a new trigger group. I think whoever owned it before you just slapped together different FCG parts together that are not compatible. Like said above. The double hook trigger might be original. But that hammer and disconnect look funky.

You can you a single hook trigger in replacement of a double hook trigger.

Also check for the disconnecter spring like said above. That spring might move that disconnecter forward.

Thank you! Ordering disconnector, spring, and hammer now. Will update when they arrive and I get them installed. You guys are awesome! I really appreciate the help.

 

[isurvival]

Parts order. Does this seem like the correct parts for the MAC90? Thanks again!

You can test if you have a disconnecter spring by pushing down on it.View attachment 967767
This is with the screwdriver pushing down on it. You should feel spring pressure. Notice the gap between the hammer and disconnecter.
It should spring back to this when you have a spring.View attachment 967771
If the disconnecter flops around freely that's the problem.

Disconnector spring is in place
