C00KIE Posted March 21, 2023 Report Share Posted March 21, 2023 I’ve got issues with a project Theoben eliminator. The end of the thread for the filling adapter is ********, the shader valve screws in nice and tight but the remaining threads in the Ali are not man enough to hold the fill adapter in place. I can’t unscrew the retaining grub screw in the Ali block to remove it in order to turn down another the same. All I need is the “filler block” at the rear of the ram with a decent thread on. Failing that, if it’s a whole unit ( can’t remember the last time I took it apart ! ) I need the ram set up. Been going through the cabinets trying to finally sort out my stuff and remember that’s where I got to last time then just shoved back in for another day !!!! Anither day just arrived as I was bored after surgery and wanted something to do ! Failing that does anyone know where I can glean any more info from . Cheers in advance Link to comment Share on other sites More sharing options...
Dasher Posted March 21, 2023 Report Share Posted March 21, 2023 Don't know if it complicates matters but I guess your gun is FAC and subsequently what parts of the pressure system are covered under that ? Link to comment Share on other sites More sharing options...
C00KIE Posted March 21, 2023 Author Report Share Posted March 21, 2023 Yes mate FAC. I need an exploded diagram of the rear of the rifle so I can explore it a bit more but essentially the gas ram itself and valve etc have to be rated quite high. I know the valve is 4000psi or something like that ! Link to comment Share on other sites More sharing options...
Dasher Posted March 21, 2023 Report Share Posted March 21, 2023 I don't know but is it worth looking up HW90 for possible parts and diagrams? https://spares.bagnallandkirkwood.co.uk/weihrauch/weihrauch-hw90-spare-parts-2/ Link to comment Share on other sites More sharing options...
C00KIE Posted March 21, 2023 Author Report Share Posted March 21, 2023 Nice one, that’s the kind of diagram that helps, although if you look at part 2025, mine has a slimmer “tube” but the end piece that the valve screws into is what I’m after. I’m sure it comes off as there’s a grub screw in the bottom of it but it’s seized in there. cheers Ian Link to comment Share on other sites More sharing options...
Dasher Posted March 21, 2023 Report Share Posted March 21, 2023 I no expert nor ever owned a gas ram so hopefully somebody with more knowledge will help. I know the HW90 uses a Theoben gas ram and I just assumed that they were identical. Link to comment Share on other sites More sharing options...
C00KIE Posted March 21, 2023 Author Report Share Posted March 21, 2023 99.9% sure they are the same mate. Done a bit more research about part 2025 and the thinner central tube, as on mine, is the revised HE ram. Exactly the same item just Theoben rebranded it for patent reasons. General opinion is the bigger tube as on the 90’s is better or no different than the HE version. Thats what I read anyway !!!! Link to comment Share on other sites More sharing options...
