Hello, I'm in the process of reassembling my svea 123 and 123r after a full breakdown, cleaning, and replacement of old bits (packing, seals, prv pip, wick, etc). One of the stoves shows signs that it had been over tightened at one point as it goes past the "1" all the way to the next window in the windscreen (points to the "w" in Sweden). The threads are clean and feel quite smooth, but the valve rests so low into the tank that it is about 3mm from bottoming out, plus it was a bugger to unscrew. My inclination would be to add a bit of non-locking thread sealant and just dial it down to the "1" position to make sure that the wick doesn't get pinched between the bottom of the valve and the tank. Is this a reasonable idea? If so, any recomendations as to a good product? For my other stove, which does stop nicely at the "1", is there anything I could/should add to the threads just to ensure their longevity? Maybe some graphite lube, or high temperature anti-seize? Thanks,
Hi all, I'll take another stab at this thread to see if anyone will bite since now I have another 123 leaking from where the valve stem screws into the fuel tank. I found Permatex has a High Temperature Thread Sealant, and after some encouraging experiments on brass bolts, I tried it out on the stove. While it sealed the threads, held the valve stem more securely in position, but was unable to withstand the heat of priming the stove. Once I burned a bit of fuel against the threads, the sealant overheated, became brittle and the leak returned. Locktite might achieve the same thing and be more heat resistant, but the idea of it makes me cringe. There is thread locker used in the fuel cap, so maybe it isn't the worst thing in the world, but I'm hoping for a better answer. Is there another solution that I'm missing? I've been searching the board quite a bit and have yet to find a solution to this
@Hazet told me about some nickle compound he used. Maybe he can add a reply. I hope to get some later. Old Sveas are always difficult to get the vaporizer off, in my limited experience.
Like a nickel anti-seize? I could give that a try. Thanks! some penetrating oil and a good strap wrench were my friends in getting the vaporizers off. I cleaned them with a soft brass brush and they are clean and straight to my eye, they just don't quite seal up the way they should.
