I have two 8r's that I am trying to dismanle and clean. I'm afraid I ruined one in my haste to get the job done. As I was trying to unthread the burner assembly from where it enters the fuel tank (which appeared to be threaded) I stripped the head and cracked the tube coming from the tank. Are these pieces soldered in as well as threaded into the tank? If they are, how does one take out the wick? I was wondering if someone could film the disassembly of an 8r and put it on u tube so we could all see Some of the other parts are very stiff to get of off my good one (the jet nipple for instance) and I am wondering if a soak in WD40 would help I would appreciate any advise.

Sometimes the fuel tube's threads get stuck fast in the fuel tank. If it is damaged as you say, I think it needs to be replaced. When the tube is bonded so fast, the torque from a wrench will only round out the faces of the hex nut at the end. If that is the case, then it is better to leave some teeth mark from a ViceGrip than have the hex nut destroyed. I use a ViceGrip and clamp it down on the recalcitrant hex nut, so it would not slip and round out the hex nut, as is often the case with a regular wrench. WD-40 might also work. I was successful with a ViceGrip, and the damage to the hex nut was only the mark of the teeth. The fuel line is always threaded into the fuel tank, and the thread is actually conical, so it tightens itself to seal the joint, as you turn clockwise.
Thank you! Both replies were helpful. The article with step by step pictures was perfect! My burner assembly was absolutely jammed and I could not budge it even with vise grips! It would probably be cheaper just to get another stove off ebay rather than order a new part..if they are available. With my second stove I left the burner assembly/tank connection alone. I cleaned every thing else thoroughly and it burns very well. "If it ain't broke, don't fix it" applies here! Thanks again. I am a new member and this is obviously a great site! Marlowe
Yes, be patient. If the case is solid, there is a good chance you can find anther 8R with good innards and rusted out case. One of the members here even picked up an 8R that had a couple bullet holes but the stove was still good. Also, don't think of the tank and burner as damaged, think of it all as useful spare parts. Stoves missing burner plates or keys etc are pretty common and go for less.
Hi I usually find it easier to clamp the hex in the vice and turn the tank than try and hold the tank and use a spanner.
Now that is the smartest way! Let the Vice do the holding. Grigryi's suggestion would work, too! Also torching the fuel tank around the pipe entry will enlarge the threaded portion, allowing the threaad to loosen up a little, as well.
When heating up the tank connection, remember the tank half of the connection will be soldered in so don't overdo it! Oh, and if you do overdo it, remember that unless you've thoroughly cleaned the tank out first there will be a lot of fumes in there just waiting for a lick of flame, and there will likely be some residual coleman/petrol in the wick that might also want to play........
