ULT = sear not catching

[need4reebs]

Yeah me too. Now I need to see what the tank is putting out. But that's enough troubleshooting for this thread.

what kind of tank do you have?

Pretty much

I appreciate all the knowledge floating around. There wasn't an Internet the last time I was troubleshooting a mag. I'll be referring to this link in the future if something goes wrong.

Thanks again

just tin cans and string to communicate back then huh....haha

dood its actually a real good thing that it took awhile to think of it...in fact the mag was diagnosed and fixed pretty quick...considering the mag is not in your hands. seriously this was like a Mag 101 class with a lot of knowledge taught as well as learned! too bad not all the trouble shooting threads are like this. usually someone will post, get a few tips on fixing their mag, and then they just disappear...no thank you, no telling what the fix was for the next person that has the same issue.

this thread was Sa WeeT Dood...haha!!!

It makes the air enter the dump chamber via its extended path - through the on/off. Since the seal was bad, the air could enter the dump chamber backwards - through the hole in the center of the reg pin assembly. In essence, with the bad seal, your marker could not turn air flow off to the dump chamber.

Sorry it took so long for me to think of it. I actually just recently told someone else to replace that, and it solved part of his problem. My bad.

Well go figure. I followed step 1 and air up before step 2 and were a single shot again. No more automatic.

No that we fixed it, can you explain what that little seal does so I can give it a stern talking to later?

Wow thanks Nak, and the rest.

If it's happening when you're holding the trigger back, the problem is behind the Level 10.

1. Regardless of what it looks like, try replacing the small oring on the aft side of the reg seat holder.

2. Regardless of what they look like, replace the small oring that sits in the counterbore of the ULT and the oring that snaps around the top brass piece of the ULT (piece with the aforementioned counterbore.

3. Replace the sear as need4reebs suggested. Although I don't think the latch is the issue, if the on/off pin engagement hump on the back of the sear is worn or was ground down by the previous owner, that could cause this issue.

The movement you describe in the sear pin is normal to a point. Can you quantify the movement you're seeing. Remember, it will be constrained by the body when assembled.

Is there supposed to be any movement in the pin that holds the sear in place? Not based up, I can see some movement in the pin; up and down. Movement in that could throw off the geometry of the sear to on/off relationship, no?

Reg pin

Anything in the lvl 10 that could cause this?

[Mic0157]

Looked exactly like the diagram. Split ring and all. Nothing was changed on it and its clean. Hmm... Air restriction up stream??? Checking on the now

[nak81783]

Oh, sure. Listen to athomas but not me. He did put it a little more eloquently though, didn't he?

Enough of my hijack. Let's get the OP's Mag working!

How's that reg pin assembly looking?


-Nathan

[Mic0157]

Okay I tore it all apart and I reassembled it correctly. Exactly like the blown up diagram. I cannot see why the sear isn't catching. So, I'll be going to the store tomorrow to see about a HP reg or simply having the, fix it. It's killing me right now.

It worked fine, I replaced old seals and dropped in a ULT which after further review, I may have already had in it. So now were looking into tanks and output. Grumble.

Unless there are any other ideas?
