Nova freedom ( pump arm locks up like valve lock!)

dan944 · Feb 3, 2019

Hi guys ,

my names Daniel and I’m from the U.K. I have a new nova freedom and havnt had it more than a week, and I’m already having problems with the pump arm locking up on the up stroke

Wondered if anyone could tell me why? It feels as if it’s not releasing sucksion from the valve area and has like a hydraulic lock very frustrating.

Im a tunner/tinkerer which is why I oerchased this rifle as I want to make it my main target rifle as I love pumpers.

i did strip the pump tube thi kingbit could have been bad O-rings but they turn out fine? So thinking it might have something to do with the valve area which takes the air ( which I’ve not had to deal with into yet ?)

please can anyone shed any light here?

many thanks

Is it locking in the closed position?

I had this happen with mine and it turned out to be the button lock. With the slightest of tension towards the lock, the handle will engage and not be allowed to open again. The quick solution to this is to simply put slight tension in the other direction with each stroke. A more permanent solution would be to file back the locks "catch" a little bit.

Hi Tom I wish it was that simple I really do, but it is in the locked position but let’s me relerelease a inch or so but has reverse suckshion like hydraulic lock or sucksion not allowing me to open the arm fully or at the moment even half way the sucksion is soooo strong !

Sound s like the air is not going through the first vale system?maybe smooth end coat hanger down into the pump tube and push through the hole to maybe free up the vale?

Your piston seal is bad and you will have to clean out the hole in the end of the piston rod. You can use a buna #006 duro 70-75 in place of the original seal if a new piston seal can not be had. Use silicone grease or silicone oil lightly when reassembling and you should be good to go.

Small update.......

i managed to strip the gun down tonight and the small oring which you have said on the tiny piston head 006 was toast.

Not yet been able to source another over here in U.K. so quickly made one from rubber washers and punches and 400 grit sand wheel. It’s pumped up to 3000 and and waiting to see if it’s held air in the morning?

if so I will test this week and see if the dreaded pump locks up again but poking good so far , especially for a home made seal , just not sure how long it will last so going to source the 006 for if and when it let’s go?

many many thanks for all your help appreciate it
