Crossman Nitro Venom Gas Ram Fail

[ryaldinhio 4,738]

I came into possesion of a nitro venom through a trade for some ferreting kit i no longer used. I wasnt convinced of the power so put it on a chrono. 4-6ftlb, something was wrong! having replaced seals now it cant even push a pellet out so i have come to the conclusion its a gas ram fail.

 

does anyone know anywhere i can get a new one of these fitted as i am struglin to source.

 

I found one place, asi crossman, very helpful guy but hes out of stock.

 

cant get one imported and fit myself as the american rams are 23ftlb and i dont have a fac.

 

any suggestions would be aporeciated lads.

 

cheers.

Had this issue in the past with a theobon gas ram i used a pump designed for these gas rams job done back to 11.5 and remained there not sure which gas ram system this model uses you may also be able to get a pump. Just an idea.

how does that work jim? i had assumed once a gas ram loses pressure it would need refurbing to hold it again? otherwise the original reason for the pressure loss would still be there???

Yeah that's a good point shouldn't of lost pressure in the first place however it may have taken years for it to drop pressure and they sell gas ram pumps at Blackpool air rifles

when I look at the pictures of the gas ram in your gun its similar to the ones that drop into bsa lightnings ,webley omegas and gammos ect .sold by theoben .awt . you may find you can put a spring into your gun you may be better of.

i have never taken anything like that on, would it be a simple enough task or is it a job for a gunsmith?

I've just taken a FAC HW97K apart, it was scary the first time, because I didn't know what to expect, but now it's routine. Just arrange all the parts that come off the rifle on your bench from left to right, then put them back on from right to left, and make sure you don't have any bits left over.

 

You don't need a spring compressor, just a bit of muscle to keep the guts inside the rifle while you unscrew the last few turns of the end cap. Put the rifle's fore-end into a padded vice and lean into it, and it won't explode all over the room. To get the guts back in, put the muzzle onto a pad on the ground, lean on it and slowly screw the end cap back in.

 

Taking it apart will also give you the chance to clean any factory gunk out with petrol, and re-lube in the appropriate places. I had a FAC Nitro Venom for a while, and modded the trigger until it broke like glass. Transformed the rifle into a very nice shooter -- pity the weaver rail was welded on at an angle to the barrel by the Chinese factory!

 

Your biggest problem will probably be finding the right guts. Email Sandwell Fieldsports with what you need, they'll reply pretty quickly by email in my experience, and tell you what they can offer. They do mail order for tuning kits etc., and if they can't help, I'm sure they can point you in the right direction. Email: sandwellfs@yahoo.co.uk

already done that, spoke to tony, no joy.

Suggest you wait until the guy you found has new stock delivered, then. Like I said, finding the parts for a Crosman over here in Europe will be the trickiest bit.

yeah im guna try him again in a month or so. i have also emailed a guy in america who was recommended on another forum. apparantley he can adjust them before he exports but i am waiting for a reply.
