[Bass Killer]

Youtube should have a play by play video

[camoman33935]

already checked there...nothin but I'll try again

[Bass Killer]

I dont think our manuals explain it either, I hope you can put it back together. Last resort, Gunsmith.

[GRIZ22]

This is one of the reasons you only take a gun completely down when it's broken.

[camoman33935]

Yeah I know...I just got in over my head cleanin...lol...I contacted Mossberg about it to see what they could do...

[ArmedLiberal]

AGI Videos are completely informational, everything demonstrated step by step. Bob Dunlap taught gunsmithing at Lassen College for decades and knows how to explain well and simply.

They have a Mossberg 500 DVD for about $40.

Yes....how far did you go and where is it at now?

I took mine all the way down and had to order a complete trigger group on Gunbroker for 35bucks as an example to see how it goes back together. Now i can do myself.The manual even recommends not taking the trigger group apart but its not that hard when you know where everything goes. Getting my NAA mini revolver back together was allot harder.

[lobo9er]

dont feel bad i do this stuff all the time :) hey man your gun its good to get to to know them. i've been there

[camoman33935]

Yes....how far did you go and where is it at now?

well...its completely apart and sittin on top of my gun cabinet

1. Get yourself a brown paper bag.
2. Put all the little parts in it.
3. Take it to a gunsmith and tell him your brother did it.

The money spent will be a good lesson for you to:

4. Don't do that again!

[camoman33935]

lol...i was actually thinkin of doin that

[juk]

we used to call cars that came in that way "basket-cases". The parts usually came in boxes or old clothes baskets. :)

I like that, it will make you feel better and less embarrassed.

[camoman33935]

Here is a better view

[camoman33935]

thanks sammy but I kinda need to know what order they're supposeo be assembled in...i cant really tell that from a schematic

[sammy_adams]

If I take some pics of mine will that help you? Cannot do it till tomorrow though. Are you in a hurry to shoot something, or can you wait? :D:D:D

[camoman33935]

I dont know if it'd help but thanks anyways...I think im gonna just take it to a gunsmith tomorrow or send it off to mossberg(not to sure of the local gunsmiths)...

[AZ_Rebel]

See my PM to you:)

[GRIZ22]

its not that hard when you know where everything goes.

I couldn't agree with you more.

First step is to clean the trigger housing really well. Me, I spray them out with a half a can of WD-40 at this stage and then wipe them down really well. It's probably the only time you'll ever have to really clean the thing. Might as well do so now.

Next, lay the pins out right. In all, there's six. Five stainless parts pins and the blued take down pin. If you lay them out from left to right by size, you'll have the blued take down pin, two stainless that are the same length, one that's slightly shorter and slightly thicker in diam, one that's slightly shorter and slightly thinner than that one, and then the really short one. If you hold your trigger guard in your hand with it facing to the left, going from right to left, it's short pin (go ahead and stick these in so you don't lose them), blued take down pin, slightly shorter than the fat one pin (the trigger pin), one of the two that are the same length, the slightly shorter/fatter one, and then the second of the two that are the same size.

With it still facing left, remove the left most one and lay it back on the table. That's the one you'll do first. It's the rebounding safety catch/sear pin. The really tiny spring with the one 90 degree bent end and the little steel tab (the sear) with the cut out notch go on it. That's parts 53 and 51 on that brownell's schematic.

I'm going to type this as I go and keep posting to it so I don't lose it all like yesterday.

On second thought, I'm not. I can't lead you through that without a ton of pics and I don't have the time to do them.

In sequence, you go rebound safety/sear pin, trigger pin (with the sear disconnector that pins to the trigger top and that connects to the sear), the action lock lever with the two odd-looking springs on the pin (thick spring on the left, thin on the right), the hammer pin (the hammer centers between the action lock lever and the disconnector and the thick spring from the action lock lever centers in the cut out underside of the hammer), and then last, the mainspring guide goes into the hole in the back of the trigger housing, up through the springs etc, and connects to the pin in the hammer (pull the tigger and get the hammer all the way forward when doing this to relieve tension) the mainspring plunger then goes in, then the main spring and the last pin.

Im having it done by somebody...but thanks anyway Rich

[RandKL]

Np, Camo. It's a part that very few folks know how to assemble and yet it's the single most prone to breakage part on the gun. Not that it's prone to breakage on its own, per se. When newbies take the stock off and replace it with a pistol grip stock, they quite often end up breaking the safety connector pin off the trigger. I charge $25 plus parts to fix those. That one tiny part constitutes more repair time on a Mossberg than *all other parts* combined.

A few years back I had designed a Mossy trigger group tool kit that made working on them a lot simpler. Simple system that most smiths are familiar with in one form or another. Problem was, getting good with it was almost as bad as working on them without it. Once mastered, though, it worked wonders. Tried for months to get several companies to manufacter it but it was the same old "too specialized to sell" crap. No biggy. More cash in my pocket.

Take care, sir!

Hi, I have a mossberg and the sear spring is busted, I took out the hammer and hammer rod and sping, no problem. i put it back togeather and took it apart again. How much do I have to tear down to get to the sear sping? I hope not all of it. Did anyone ever get a photo in detail on how to do a project of dissasembly? Thanks for any help. I have a new spring coming soon.

[RandKL]

The sear spring in mounted on the very last pin towards the front of the trigger group....unfortunately, you can't change the sear spring without removing the hammer pin (second pin) and the disconnector pin (third pin) and those are 95% of a stripped trigger group. Both the hammer and the disconnector are linked to the sear and both cover it so you can't work around them.

Send it back to Mossberg. Either that or buy a complete trigger group from gunbroker.com. Your chances of finding a decent smith that can work on that for you are next to nil. Mossberg is pretty cheap. A new group will run you $35 from gunbroker. Your choice.

Peace.

duplicated post. no idea why. mods, feel free to delete this!

I have a spring on order. I am going to try to fix it. I am not a beginner at fixing guns, but not an old pro either. I have already taken out the hammer and hammer rod and hammer spring and replaced it several times and it is a snap. I am just wondering if there is any springs that will go flying in this last operation? for 3$ if it all goes to pot I can sell the parts on gun broker and then buy a new trigger group. If it works I fixed my gun for next to nothing. I should do a video and if it goes good I could sell it over the net for 10$ a pop seeing how no one else has any videos out there on this subject. I have never been intimidated by working on things, when my Chevy ujoint went out in Vicksburg, I changed both out in the parking lot of the casino, and when the dealer wanted 1000 for new wheel bearings in the same truck after a lot of swearing I changed them out in my garage for 219. From looking at this thing is does not look that complicated, I was just wondering if anyone had ever done it and if there were any pit falls I.E. springs that go flying when taking it apart? At first I was nervous that the hammer spring was under a lot of tension, it is not, just push the pin out and remove the spring and the plunger comes out remove the rod and than the pin for the hammer, the only thing to remember is make sure the half moon cut in the rod goes down toward the trigger and the c goes into the rod in the slot of the hammer and there is nothing to that operation.

[edwood]

I got the spring. The sear spring was not that horrible hard to replace, I used a nail cut to hold it in place until I could get it in and push it out of the way. The hard part was the disconector springs. If there were posted photos it would be a snap. My problem was I had no photos to see how the springs went back in. It is not that hard once I found a photo of how the springs go in. This is not the best design. The sear spring could be a strait like the hammer spring, with another pin that holds it in place and you could replace it with our taking any of the others out.
