    Theoben HE system went BANG on cocking

    AS above went bang on cocking. Stripdown followed, shrader valve out but still under pressure as i was unable to remove the large circlip that holds it all in
    anyway into the lath with a bit of offset apply pressure and remove circlip. Unwind and pop again (so be carefull)all stripped down O rings sourced and time for Re-build
    So wanted advice on lubricant on the gas ras ram (Not piston) I.E silicon or grease or advice taken

    A teaspoon full might be a bit much...…. interesting that the OP still had pressure in the system after unscrewing the Schrader. This is the pressure that has got in behind the (unvented) inertia weight I suppose. Out of sheer nosiness 10/10, did your inertia weight have a small hole drilled through it or not? I remember Rhyslightnin and I having to drill a hole in his in order to relieve pressure and allow us to strip the rest of it all safely.

    Seriously mate, let it go. You got found out, you got banned & your back, dont give yourself a bloody migraine. I only commited on this thread because I was reminiscing of the sinaro at in severnsiders shed when we were drilling a hole in the inertia weight on my gas ram, the hilarious thing about it is we were both slightly worried about what might happen as we knew there was allot of pressure trapped behind it so as severnsider was cowering behind me I tentatively pushed the arm of the pillar drill down. All that happened was this pffffffffffffft! (As I had suspected but your never quite sure ) And it spat oil & swarf all over the drill chuck...,
    You never know I may be able to help you with that nice new SLR you bought
