Mole grips !!! Bloody shell won't that damage the cylinder? I can't think of a reason why it would be so tight, it should just sit on the O ring. I take it the barrel is off? If so I would clamp the action in a soft faced vice, apply a little heat to the cylinder where it meets the block and then u...

Thanks for all the advice guys. A vice & a lot of force got it in the end!

Cheers brooksy I couldn't move it with a pair of 8" mole grips so it's going to need a lot more force than that. Can't believe how easy it looks in that video to unscrew them!

I was dubious about it but willing to try almost anything! I'll try the vice & elbow grease then. Thanks for telling me about that, although you've just done yourself out of a sale for a new gauge block

Thanks for the offer Julian but I'm in West Yorkshire so a bit of a treck! It's been suggested to clamp it in a vice with some wooden blocks & put a spanner over the gauge block for extra leverage so I'll try that in the morning. Just puzzled as to why mine is so difficult to get off as they are...

I'm absolutely certain, dry fired until it dumped the last of the air. Also made sure I could push the valve with the hammer! This seems to have quite a few people stumped!

Arrived this morning, thanks Julian

Hi all, Has anyone has any experience of a really stubborn air cylinder. I've emptied it of air & am trying to remove it to inspect the inside & fit a de-pinger from Julian. I have tried heat & gripping it with a latex glove to give more grip but no joy. All the strip down videos say it'...

Thanks for the quick reply. Payment sent
