Hi All, Just got this lantern from someone who has kept this lantern in her basement for the 20 years. Sadly there was fuel in it. So not surprisingly it doesn't work. I emptied the old gas and replaced with fresh coleman fuel. When I pump it up, I can't get any pressure. I'm doing at least 50 pumps. Any thoughts? Thank you, Chris
Hello Chris and welcome. It sounds like either the pump is not working or the rubber seal in the filler cap is not working or possibly a combination of the two. Take out the pump and inspect the pump cup, it's some sort of synthetic material but it could be split or torn and will need replacing. If the filler cap seal has gone hard, it won't seal properly and air will escape as fast as you can pump it in. If you have difficulty locating spare parts locally, oldcolemanparts.com could have what you need.
One thing to note regarding those 222a other than the pump problem you got, careful of the fluro something o-rings as they will leak over time given how long it was stored or used before storage.
These lanterns always worry me. I have three of them and they are neat looking things that look great and work well but I don't like the valve gland O ring seals. Unlike most lamps we play with the gland seal can't be tightened if it leaks. They rely on a ratchet type clip to retain the O ring so the integrity of that O ring is vital. I would strongly suggest replacing the O ring and a pressure test if the lamp has been stored for any length of time. ::Neil::
This is great!! Thank you for the responses. I guess I will start with the easiest and check the leather.
Hi All, Following up from my July post. So this fix was intended to be winter project. Which I attempted this weekend. Went from easiest to more involved and cost. Replaced the filler cap rubber; still no pressure. Replaced the pump (the parts today are so flimsy compared to originals) and leather. Was able to build pressure. Which was nice; so not the check valve!! But, still not able to light it. I could hear and smell the gas escaping, but wouldn't light. So I'm assuming it's the 0-rings in the valve stem that Mackburner was suggesting, that need to be replaced? Going winter camping in a few weeks, so would like to get this working by then. Thanks, Chris
Not likely to be the valve stem seals. Failure there is just a fire hazzard if raw fuel leaks but that wouldn't stop the lamp working. These are an "Instant" lighting lamp and have a fuel/air pick up in the tank and air discharge without fuel probably means the tubes are clogged so I suspect you will need to unscrew the valve from the tank and clean the fuel feed tubes. ::Neil::
Neil, would you have a link or a suggestion to a video that I can watch to disassemble a 222a. Or would any video I find disassembling a coleman lantern work? I found one fellow putting a 222a Peak lantern back together, but he sped through the process and was unable to understand the process. Thank you, Chris
OK I have taken apart the valve and the generator. It doesn't appear that I can disconnect the fuel tube from the valve body. It looks like its' soldered. The fuel tube is very different from a video I watched () The notch in my lantern is at the top of the fuel tube, unlike what is in the video. Can anyone suggest a solution to soak everything in a attempt to clean the valve and the tubes? thank you
Thank you for the post. The fuel tube looks different. Ive included a picture of mine. Would a cleaning solution of vinegar and water, work to remove carbon buildup?
Hi Chris. You may need to use a blowtorch to heat up the connection between the aluminum valve body and the brass FA tube to make it easier to unscrew. You don't need to give it much heat. When reinstalling I usually use a little bit of blue thread sealer on the FA tube threads that screw into the aluminum valbe body. I don't know if that's actually necessary. I usually spray a bit of carburetor cleaner spray down the FA tube. If I see the carb cleaner drip out of the bottom I know it's good. I usually use Simple Green cleaner with super fine 0000 steel wool to clean gunk and buildup off brass parts.
Hi Folks, I'm somewhat defeated right now. I was able to take everything apart. Thank you Newfie, I used a heat gun and that did the trick. I separated all the parts, cleaned them with brake cleaner and a pipe cleaner and then used fine steel wool to polish everything. Replaced the o-rings. Put everything back together, new mantle, fueled up, pressurized and then nothing. I could hear and smell the gas escape, but no ignition.
Silly question, but does the generator of 222a lantern have a hole at the end of it? If it does, I can't find it. I cleaned the generator parts in boiling vinegar, as per this fellow's suggestion: . Put it all back together again and again nothing. The other thing I noticed, the tank depressurizes rather quickly, with the knob in the off position. Is that normal?
The gas tip on the end of the generator will have a hole in it but it is very small and not easy to see with the naked eye. If everthing is in good order, your lantern should not be losing pressure. Empty out the fuel and replace the filler cap. Remove the handle, top cap, glass and burner. Pump in plenty of air and hold the tank, valve and generator under water, air bubbles will show you where the leak is. Operate the valve/needle control, air should escape from the gas tip when "LIGHT" and "RUN" are selected, if it doesn't, the gas tip is blocked and the needle will be either bent or broken.
… and here it is magnified by the Eschenbach 5x/20D/140 ! (made in Germany) If I can make or obtain a device to hold it in position then I can split the atom if I can find it !
