D34 will not shoot (T06 trigger)

[Skinard88]

My D34 does have a PG2 kit, but I have not done anything to the trigger. when I cock it and pull the trigger, nothing, I decock it and cock it and it will fire. I can shoot for a while and then it will not fire again. I decock it and cock it and sometimes it will fire and sometimes it wont. When it does fire the trigger feels fine and it shoots great. when it doesn't fire, the trigger feels like it would when the gun is not cocked. Thanks

Assuming that you didn't do any trigger work...  You might want to confirm that all of the pins in the trigger housing poke all of the way through each side.  They are not locked in place, and one or more of them could have been pushed into the housing, such that it's tilted and only being held in by one side.  I wouldn't think the trigger assembly would fit in the stock with one of the pins sticking way out, but this is the only thing I can think of.

Before I did this post, I took the action out of the stock and checked the pins, that was my first thought. I like the trigger right out of the box so I haven't done any work on the trigger. I have thought about it just to learn how to work on these triggers. when the spring broke that when I learned how to do a tune so it looks like I'm about to learn T06 triggers. Thanks for your reply.

Did you add preload shims ? ... too many and spring can go coil bound before latch rod hooks up.

You can cock the gun and it may or may not fire.  You can always decock it.  If this is true, how does this work?  I can decock my Diana by holding the barrel then firing the gun.  I can then ease the barrel closed, releasing pressure on the spring.  If that's how your gun is working it seems that when there is pressure on the sear something in the trigger housing is not in alignment.

With the gun uncocked you might try dismantling it again, paying special attention to the trigger package.  Look to see if there is side play on any of the pieces which would allow them to slip off the sear while you're trying to fire the gun.  The addition of a small washer to reduce internal side play may be a means of curing your problem.

This is not necessarily a potential solution - more like food for thought.  It appears that something is almost right, but not quite.

Thanks for the replies,  Motorhead, no I didn't use any preload shims, and I have been shooting this gun for months when it started to act up.   Roadworthy,  when I decock the gun, its the same as yours. but when the trigger fails to fire, I break the barrel and on the way down you get to a point and it lets go, on its own, and I ease the barrel back in place. I cock the gun and it will fire. most of the time. when I had the action out of the stock I checked for any thing loose but didn't see anything. I put the action back in the stock and shot it about 25 rounds and it didn't do it again. Ill shoot it some more today and see. I was thinking of cleaning and relube the trigger. maybe some dirt is the cause?       Thanks

Trigger assemblies have some parts of their design for resetting things, mostly cams and springs come to mind.  More often than not if it is a mechanical failure it will be the weakest link, a holding surface malfunction (chip, burr, wear point, or foreign object), or a spring that broke (work hardened, rusted, or had a defect).  My guess is a broken spring in the trigger group.

Maybe you can see in with a flashlight?

OK guys, I have been shooting my 34 on and off all day. put about a 100 rounds down range, no problems. I guess taking the action out of the stock and blowing on it and putting it back in the stock fixed it. Next time this happens ill spend more time messing with it before I bug Y'all. Sorry for the false alarm, and I THANK EVERYONE for their replies.

I wish I had $100 for every time
I took a part off a malfunctioning motorcycle/car/ reloading press etc
stared at the part-found nothing "BROKEN"
put in back on/in
and the malfunction was GONE

Yeah one of life's mechanical mysteries 
BETTER TO BE LUCKY THAN GOOD!

Maybe screw tension or uneven alignment with final tightening last time?  Glad you got it shooting - I'm certain if you had sent it to Umarex they would have said it was fine and billed you a service charge...

... and sent him the wrong part back!

I don't have the parts diagram in front of me but you have broken one of the trigger springs.  It it the one with the 2 legs.  You broke one of the legs off.  The other one is still good which is why it works most of the time.  I am out of town but I can post the part number next week.  Take the trigger group out, take the trigger apart, and you will see quickly what I am talking about.  Putting the trigger back together is a pain but you can figure it out.  Just some trial and error type stuff.

Brazos is right, I had the SAME issue with my .177 d34. It was the tension spring. Forgot the part number though.

[Skinard88]

Thanks Brazos and Jringe, I know what spring your talking about. Ill take a look tomorrow.  I see little problems like this as opportunities to learn. Thanks.
