Imp Noob needs help

[rmarion]

OK here is the story. I bought and imp today. It has a max flo regulator and I believe that is its only upgrade. When I attach the HPA tank it hemorrhages air from the regulator. I believe this is a model that is a little older as it looks nothing like the one on the web site. if anyone has any ideas let me know.

It sounds like it is coming out of your PRV. Decrease your output pressure (turn the adjustment cap counter-clockwise). Under 200-220 psi the PRV should stop venting.

[speedy2k4]

yup try turning the big cap on the regulator counter clockwise, see if it stops. if it doesn't, post a picture telling us exactly where the leak is coming from.

and for the record, all impulses come stock with a max flo reg, but there are several different versions of the reg, gun mount, old vert style and new vert style, they don't all look alike.

*edit* alright, the shocktech superfly impulse came with a shocktech reg. every other impulse comes with a max flo

[rmarion]

By counter clockwise what do you mean. I know that sounds dumb.. wait a minute it is.. but I still dont understand. Imagine I am looking at the gun down the barrel. Would going clockwise that way lower the pressure.. So the looser the spring cap is the higher the pressure.

I know that is a lot of nonsense but I would appreciate the help.

[Team Chokepoint]

Rotate the cap away from the rest of the reg to lower the pressure. Turn it to the left.

[Bokuwakakera]

I am thinking you have the same prob I had. (look at the picture)


If that is where its leeking from, then your pressure is WAY to high.

[rmarion]

I cant tell if that is it as my reg looks completely different than that. My imp is a pre release model so the parts are a little older. Do any of you operate a repair shop that could fix it , or am I better off send it to the factory to be rebuilt.

[Team Chokepoint]

You probably have a vertical max flow (the reg is like a fore grip). The PRV is that brass hexagonal prism sticking out of the side of the ASA (the part that your reg screws into). Is it or is it not leaking out of here? If so, decrease your pressure like we said above. If not, then we'll need some pictures to pinpoint the problem.

[ase]

there should be an o-ring above the threading on the reg that screws into the asa. make sure thats intact.

wrong attitude. you can fix it yourself, impulses are incredibly simple, even the max flo. maybe post a pic of your max flo, and highlight or describe where the leak is coming from?

[rmarion]

I'll take that!!! So here are some pics

This is the reg, obviously. I dont think it is leaking from the brass piece on bottome but I really can't tell where its leaking from.

In this one I want to know how to disconnect my macroline.

[speedy2k4]

very early model gun mount max flo. if it isn't the prv, check to see if it is coming from the guage or macroline fitting. is it just a little hiss, or a big hiss? you might need to change your o-rings/clean and re-grease the reg.

also, that macro fitting on the foregrip, looks like one of the communist variety, very hard to get the hose out but same deal as any other. just push back very hard on the metal ring on the end of the fitting, right around the hose, hold it back and tug on the hose itself. it may take some elbow grease on that one.

[rmarion]

yeah it is a pre release impulse. i got it at a flea market. Good deal for a poor spyder user! I cleaned everything and relubed the Orings with DOW 33(which grainger has on sale now for $11.00 if you are running low.) and reassembled. I have no air to test it until tomorrow.

[speedy2k4]

alright, sounds good. and before you air it up, turn out the adjusting cap on the reg all the way, and then slowly screw it in. it is possible the guage is a little off, and if the pressure gets turned too high, it would leak.

also, do us all a favor- save up $30 and put a nice triger on there :)

[Team Chokepoint]

Whoah, old school.

[rmarion]

yeah . I was tempted ot send to the plant and have them rebuild the gun. The rep I spoke said they would do that for $75 but I have to hassle with the shipping and waiting. Maybe in the winter!!!!

[rmarion]

Ok Genteleman. Thanks to your help my reg has quit leaking. I am now losing air from around the bolt. It is also moving the bolt forward when I attch the air. Any thoughts.

[speedy2k4]

hammer assembly or solenoid. try cleaning the hammer first, check the o-rings. or is it leaking from the front of the bolt, down the barrel? in that case, tru cleaning the valve/replacing valve o-rings.

[rmarion]

any reason why that would move the bolt

[speedy2k4]

does it just move the bolt all the way back to the rear position?

[rmarion]

OK I cleaned the valve and the such. Still leaking. Imoves the bolt from the rear position to halfway.

[speedy2k4]

alright, well then we have some work to do. you will have to go inside the ram assembly to change o-rings, which means taking off the back cap, removing the hammer (which may require heating) and then removing the ram to change the o-ring on the ram, and the o-ring at the front of the ram housing.

if that doesn't work, you have some issues with your solenoid, and i don't think just a gasket problem. so you will most likely need a replacement, assuming the ram isn't the problem.

[rmarion]

I just called tech support for about the 8th time. They say when the bolt does that it means the Solenoid end cap is on upside down. So I am going to try that. Plus changing the Orings again.

[speedy2k4]

the end cap upside down...i guess that might do it. let me go check, i've never turned my endcap upside down before :crazy:

[Team Chokepoint]

I did that accidentally once...I thought my gun was totally f*'d up when I tried to cycle it :crazy:

[speedy2k4]

well i tried it, and it leaked. it didn't move my bolt at all, not even when i tried to fire it. but try to reverse yours, it should do the trick.

[Team Chokepoint]

I don't remember what mine did, all I know is I almost crapped myself. The board seemed very confused as to whether or not it was operating a closed- or open- bolt gun.

[speedy2k4]

yeah it is never good when your board gets confused. nothing good can come from a confused circuit board :laugh:

[rmarion]

is there a way to tell if it is Upside down.

[speedy2k4]

not without taking it off. you might as well just flip it and see if that fixes the problem

Actually, you can tell. There is a raised nub on one side of the solenoid end cap that should be facing the body. If you can see it when you take the tray off, then you need to reverse it.

[speedy2k4]

:confused: my nub doesn't seem to exist? maybe it got worn off, along with all the stickers. meh, listen to TC, sometimes my parts are a little "off" :laugh:

[rmarion]

well I started replacing part with NDZ parts and whn I replaced the hamer and ram my leak went away. The interior part of that device had been worn by the previous owner. So I ant to say I appreciate everyones help. Also per your suggestion I replaced the trigger with the magnetic blade trigger.

[speedy2k4]

so it was the ram? yippy! i was right for once (kinda) :P

and yeah, ndz=king of the impulse world. you can't really go wrong :tup:
