I recently needed to remove my RC valve and turned to the forum for advice...there are lots of pages referring to this subject!
I read about claw hammers, acetylene and all sorts of other fairly robust removal methods which worried me a little.
So in my opinion if it is at possible you could try a more gentle approach first.
- try to remove the dust seal, it is a metal reinforced rubber seal so its quite a tough cookie... if it won't come out easily don't worry
- find a spacer or something that sits on the cylinder face flat but does not cover the hole with the dust seal in, I ended up using a 19mm ring spanner
- place a 10mm hole penny washer over the RC valve shaft and sit it onto the ring spanner
- keep placing other 10mm hole washers over the valve shaft until you build a stack up to the threaded area of the RC valve shaft
- locate the retaining nut onto the rc shaft (left hand thread "so lefty tighty, righty loosie") and start to tighten the nut down onto your washer stack
- don't hang on the nut, the thread is not going to take your bodyweight, just apply steady pressure and get the whole lot moving, then back off, then re-apply force etc etc
- when you get to the bottom of the threaded area, add another washer and repeat until the RC Valve is yours and you can raise a glass at your gentle sympathetic engineering skills!! 🍻
HRC would be proud of you
