BlackVCG's ULT Thread

what problems are most likely to occur if the on/off pin is bent?

i may have bent my pin, barely perceptible but i know that in a mag tolerances run tight.

the bolt is not resetting fully, it gets stuck about 1-2mm before it fully resets, could a bent pin be the cause?

also, is gold cup oil better than autolube for the Xvalve?

please help quick, i have a game on sunday!

thanks in advance.

Hey bro, if your on/off pin is bent, I don't think it will cycle at all. I'm having the same problem. I'm thinking about finding a washer that'll fit around the outside of the bolt but not exceed the diameter if the edge and see if that takes care of the re-cocking problem. You could also stretch that medium spring out, buuuut stretch it too far and the gun won't fire

Hey, two shims in the power tube and six on the ULT and my gun sang like a pro today. Only sticks when it's dirty, or low on air so make sure it's clean and gassed. OIL ON THE ON/OFF MAKES IT STICK!!! It causes a vaccuum and it doesn't cycle as easily as it would if it was just clean with a extremely small amount of oil on it.

Can some one make it a little more simple...

OK, I've read through all of the posts and I'm confused as ever...

What is the end effect if I ADD more shims to the ULT? Lighter trigger pull?

When is the end effect if I REMOVE shims in the ULT? Heavier trigger pull?

I've been racking my brain all morning playing with mine. I finally got the Level-10 tuned properly and now moving to ULT.

haha, yea I was confused as hell too. I had to print out the instructions and the diagram and re-read everything like twice. At any rate, more shims on the ULT doesn't mean lighter pull, persay. It means a SHORTER pull. The shims are only what-----a 1/32nd of an inch? But they certainly make a difference. TRUST ME. You're not going to want more than 6 on there. The instructions say if it goes full auto take one out, but i asked another tech and he said that it's ok, as long as the gun stops shooting when you let go of the trigger. Happy trouble shooting !! Hope ya gotta full tank of gas.

Level 10 should be fine, shooting 280 pretty steady, removed one shim because I was having an issue where if you put a little weight on the trigger it would start leaking, and it has no leaking down the barrel. I'm somewhat convinced it has something to do with the on/off or sear as it also shoots often when I gas it up. It sometimes lets the bolt move forward and stay there venting when I gas up and then if I reset it or let it fire, it's fine, I don't have a clue what's up.

if you marker fires when you gas it up your o ring in the center of the valve has came loose split your valve in halve the small white o ring should be seated in the brass piece and not on the pin (i asume this is an x-valve) just lube the pin good, reinstall gas it up, and it should be fixed

What is the output pressure on your tank?

Have you tried adjusting the velocity?

When it quits firing, did you try to push the bolt back with your finger to see if that will "click" the bolt back onto the sear?

Who did you send it to?

Do you have access to calipers and if so, can you measure the length of the pin assembly from the top of the pin to the bottom of the larger support pin?

Ok. I have gone thru and tried everything I know to try which is limited. Now when the gun is gased up, the trigger puts pressure on the trigger but it will not fire. I turn off the air & remove the tank & the gun holds the pressure. It wont release the pressure until I disconnect the macroline and begin to remove the valve from the body and it will fire.

Thanks

Turn up your velocity?

[Ken Majors]

I installed the ULT kit. I cannot put more than 4 shims in the on/off or I cannot get the on/off down far enough into the valve so that I can slide it into the body. It sits up just enough to not allow enough clearance to get the valve back into the gun.
With 5 shims it is a no go...with four it goes in but has very little effect on trigger pull. I must be doing something wrong.
If anyone has any ideas....they would be appreciated.

ult shim help

i have a few issues i would like some help on,i just got the ult pull kit droped it in with 2 shims to start. trigger pull felt good but it was my understanding to add shims until it goes full auto then take one out.so i am now at 5 ult shims and 1 lvl-x shim and it still has not went full auto and i cant fit any more so what should i do also now when i gass the marker i shoots once and i have already checked the o ring in the center of the valve to see if its seated in the brass piece and it is,any ideas? also please tell what more/less shims do in the ult

[nipplez]

when you guys oil the ult, do you take the entire assembly off and oil each oring and the pin?

i got 7 ult shims in mine and it works great.

setup

xvalve
lvlx - no shims
ult - 7 ult shims
crossfire 68-4500 preset 800psi

[two_four_878]

Okay, I can't read this entire thread.

Here it is, I took all the shims out of my ULT and it still goes full auto when I try to fire it. I have no clue what to do.

The problem was the feild strip bolt was not tight enough. The aluminum rails have to be tightened just right. Thanks for the help.

How do I know if I have too many or too little shims in my ult on my hyperframed xvalved mag? I played saturday with a gun that had a slow leak every other shot, capped at five(it would chuff if I went faster). How do I fix this. Yes I sound like a nob, but I dont care. I need this ripping. tornament soon.

[mark_1791]

Is the ULT recommended or not recommended for mags with Hyperframes?
