My G3 keeps failing me

s7chaos · 01-10-2010, 06:14 PM

I have been having an issue with my G3 for a while now.

Conditions:
Fresh battery, everything greased properly, new reg parts from DP installed, 7th element board, stock bolt, LP 4500 tank. Gun is first generation G3

Symptoms:
At first, the gun would leak and not cycle. This happened at the beginning of the day and would clear itself up after 5 or so dry shots.

Then the gun began to not cycle at all. The solenoid would not budge if the gun was gassed up. I removed it, regreased it, tried again. Nothing. I put oil into my ASA and a half drop directly into the solenoid.

It now cycles, I can hear it clearly. What it does not do is shoot. There is gas behind the bolt and in the gun (indicated by degassing through the reg afterwords). But there is no bolt movement. I have upped and downed the dwell between 9 and 14 and still no change.

Any ideas guys?

check your breech oring or sail oring one of the orings is making the bolt to stick and dont over lube.

check how much lube is on the back cap bumper where the bolt rests.

I agree with the above. I suspect you are having a sail o-ring issue which is very common on these markers.

Hmm, so the sail oring is the one the bolt rests on at the back cap? It seems a little dry, I will re lube it. Same amount as the rest of them?

1) check the sail oring (#3 from the front of the bolt)

2) If you don't hear your noid clicking, change to a new battery

3) remove all the grease and relube only the minimum amount needed for the bolt to slide. LESS IS BETTER... I am assuming you are playing in colder than normal conditions since it's winter. Apply lube only prior to playing.

4) Close your reg all the way and slowly increase the pressure

New noid.

Bolt sail o-ring.

Brian Rodela · 01-11-2010, 06:33 AM

S7, no the reason I asked is because some make the mistake of lubing that bumper on the back cap and it causes bolt stick. Sorry for not clarifying it.

s7chaos · 01-11-2010, 10:24 AM

Ah, ok. The sail o ring has been properly lubed, the backcap oring is still unlubed. The gun still does not fire even though the solenoid is moving. Could it still be a noid issue even if I hear it cycling?

mik2ball · 01-11-2010, 02:25 PM

take the backcap off and push the bolt to the forward position. Put the back cap on and air your marker, does the bolt move back? It is does, then you have good lube on the bolt, but need to thin coat the backup plunger oring.

If you have PMD check your pressure. Might need to be turned up or your dwell needs to be up to 14-16ms.

Remember guys, this is a colder than usual winter for most folks, things change due to the weather and it's not the fault of the marker. It has to do lubes and orings most of the time.

rottensquad07 · 01-11-2010, 03:11 PM

My bet is still on the sail o-ring being worn down enough to the point that it cannot seal consistantly. I would replace that o-ring with a spare o-ring in the correct size and then try again. I would say that about 90% of the bolt not cycling problems can be traced to this one o-ring.

+1...I am just assuming he went through the previous checklist I posted. Can we sticky something for cold weather play?? Seems like very common problem that keep reoccurring and we don't need new post everytime

I can personally say this marker is not the best for cold weather play. Most spoolies tend to have issues in cold weather. The only exception I've seen is with the SP1 and Vibes, for some reason they don't seem have issues in cold weather.

my G3 dont have issues with cold weather.

rottensquad07 · 01-13-2010, 07:35 PM

My Threshold and REV-i have no issues in cold weather. It really just depends on the type of lube and how much is used.

nymisfit · 01-13-2010, 07:50 PM

When our group was playing in 32 degree weather even the guys sporting DM8s had issues with bolt stick as did 3 G3s and 1 Rev-i. We used every lube in our arsenal to no avail.
