Hammer spring replacement

Sun Jan 28, 2018 2:23 pm

Hi all
I was adjusting the pressure on my Swedish (logun) axsor gemini sub 12ft/lb, and I think my hammer spring has broken. I was adjusting the pressure on the spring and everything has just gone slack. Cannot feel anything on the adjuste either way I turn it. I can replace the spring no problem, but my question is, is it safe to strip down without emptying the air or should I empty the air before stripping it down.
Normally I would empty it but just wondering if I have to?

I wouldn't have thought so, there is a strip down guide on the airgunforum. Rog

Do you mean you don't think I need to empty the cylinder.
Cheers

Hi Kev, I wouldn't like to say that I'm 100% sure, if it was an AirArms I would be, but normally when dealing with Hammers and Hammer springs I can't see any reason for decompressing, but not having dealt with a Logun, just saying I wouldn't want to be responsible for you damaging yourself, not all that helpful I know, but better safe than sorry.

Thanks rog.
I will be decompressing the cylinder "just in case".
I have just filled the gun and was being lazy. It's just a pain dry firing so many shots.

You stand a real chance of bending the exhaust valve if you shoot the pressure down to empty it. I'm not familiar with the specific model, but assume it's one of the many rebranded FX 2000 family. The exhaust stems are around 3mm to begin with, and this is further grooved for an oring gland. New ones are not too easy to come by here. You can safely work on the hammer area with pressure in the tube. The safer way is to loosen the pressure gauge to bleed down. There used to be a great resource of info in the FX Owners Club forum run by Polarwolf, if that site is still up.
