Does anyone know the answer to this question...

[dwarren]

It's the 3rd time I've ask on this site with no replies..."could someone tell me how to get the Nitro Venom barrel in the decocked position without cocking. Do you just shoot it and then remove the pivot bolt. Want to decompress the gas chamber and check seals, etc. using a strong clamp instead of  spring compressor. Clamp has opprox. 36" opening."

Thanks for any help on this,
Don

Don,
You may not have had many answers because you question is a bit confusing (to me anyhow). I have read it a few times and I now believe I understand what you'd like to do: namely, remove the barrel and then use a big clamp around the compression chamber as a spring compressor. If so, then you can do as you have suggested, ensure the rifle is not cocked (could be by firing it first), then remove the pivot bolt and remove the barrel and cocking arm. You can then secure the forks of the receiver against the fixed jaws of your big clamp and the rear of the compression tube against the movable jaws. Make sure your clamp is up to the job.
Good luck. Duke.

If it's cocked, fire it with a pellet.
Then you should be able to remove the pivot bolt without danger.
I assume you want to remove the barrel before opening it up.
Am I right?

You might not even need to go that far.... the nitro venom only has 5mm preload on it at the most. No need to expect a massive energy release as you would with a springer. If you still feel you need to, break the barrel loose without completely cocking it and remove the pivot bolt as suggested. I apologize for not seeing your question earlier.

Thanks for the quick replies...I want to remove barrel..there's a video on Utube that shows just what I want to do, but I can't get it to post on here..it's been posted on here before so I'm doing something wrong. I've got a clamp like the one in video except it's a screw type handle.

I don't like your clamp.  The screw type handle is good but your wrist may not be strong enough to put enough pressure on the gas spring.  I prefer the clamp with a crank type handle for tightening.  Be sure to secure the gun to the clamp so it doesn't shift.

Before starting, ensure gun is not cocked.  Remove the scope.  Remove the stock - use special care with the screw accessed through the trigger guard.  Many plastic trigger guards are used and they break easily.  Remove the pivot screw.  Remove the barrel.  Some recommend removing the beartrap linkage from the trigger assembly as well.  It is retained with a clip, there is a spring there as well.  Don't lose it.    Be careful not to loose the little plastic piece on the cocking linkage as well.

First off I was concerned about some the clamps of this type's bar strength..the longest part..this one is pretty stout. But, I'm concerned about the holding mechanism and shallow teeth in the bar. Thought about getting it close to where I think most pressure is and clamping down heavy vice grips on the bar to help stop a a full slip at most. But, I think this screw type will give more control than the squeeze type.

Never thought about the strength needed for the twist thing..may have to use some kind of clamp on helper..if room and handle doesn't break.

Once you get the action out of the stock all you have to do is remove the cocking foot from the cocking slot and you can open up the breach all you want without cocking the gun...

I own a venom also. I removed the gas spring by simply placing the main tube minus barrel, onto the rounded side bolt head on a pair of Chanel lock pliers laying on side on floor. Place the little hole on the spring retainer on the pliers bolt. Stand it vertically and place a large hunk of regular lumber stock, I used a 2x6 about 10-15 inches long, on the forked bare less end. Just rest your body weight down onto the  board while being sure to keep it straight so it will not slip and  hit your chest. I found that not a lot of pressure was needed to relax the spring pressure on the retaining pin. You can feel it shift just a bit to tell that enough pressure is added. Use your hands free while your chest rests against the wood/spring tension. I used a very small bolt to push the pin and just 1 or 2 very light taps and it just slid right out. Putting it back was just as simple but be sure to align the pin holes with tube before compressing. Also put the plastic cap on before you put the trigger retaining bolt into the 3rd hole. Another way was to place a large brick or more lumber would work. On the ground near a taller sturdy object for a levering point. I placed a xl1100 .22  assembly in the same way as above but had to resort to a levering approach. I.e. I went outside by my back deck that is raised from ground about 2 feet . placed a large brick on the ground, placed pliers on side on top aligned hole with bolt head, then stuck a 4 foot piece of 1x6 under the edge of the deck but on top of the forked  bareless end. Brick and tube where in front of deck by about 1 foot. It was  very easy to lean body weight down on the levering end of the 1x6 and releave the xl spring tension. Tap the pin out the same way, very easy to do alone. Putting it back is just the opposite of removal, just align holes first. I never used any special device, clamp,bolt mount etc.etc. i can not recomend this approach to all but it has worked for me many times with many nitro rifles. just pliers wood and a small bolt. I am not a light weight either I am about 200 lbs. My little belly may have helped for once lol..... bambam
