Hello I found this little stove yesterday and think it’s German make Says on tin box original Enders and on the stove it had a copper plate with name and number 9069D . does anyone know how to take out the air tube ? I opened the pump and uncrewed the nut as in pictures . it seems to have a black hard washer or similar stuck to the tube and is not moving . Any suggestions how to safely remove the tube , or do I just leave it as is . I was thinking there is a pressure pip at end of the tube . What kind of washer will be ok to use . there is a washer for the air pressure fitting on the tank as a spare part . I been trying to look up for information but nothing about this model 9069 D model . any help and suggestions on this stove is appreciated . Is it old and is it German ?
Hello Jim, the Air tube is fixed with the NUT SW 24mm, the pump is inside in the smaller one Nut wich is crewed on the big Nut. Try to get the airtube out by destroying the seal seeing ion picture 1296 all the Enders Airtubes are nearly the same: (here a airtube from a Enders Neptun with a other way of valve) If you can use something like this: the second , but danger way would be, to burn the seal away, for this it's necessary to clean the tank absolutely from fuel, better to fill it with water bei open Tank! Good Luck RJ
Thank you for the detailed reply . I will definitely try to carefully remove the seal from the fuel tank so to remove the air tube using tools you shown . And maybe heat the seal a little before . so the air tube is not broken in any way with the nut away from it … the nut actually puts pressure on the seal and lip of air tube when closed . I was thinking they were both soldered together , but seems not . . When I have removed the airtube I will try find a correct seal to replace old and post more pictures and details . Thanks
Thank for all the info Been doing research all day on this stove and saving all details about washers and seals etc etc … Was serching on line for Sefaudi service packs but I thinking he was finished with making and supplying . As I’m unable to find his online link . Regarding the airtube and seal . I have tried picking out seal but rock hard and I’m careful not to damage any of the brass threads in the process . im also thinking if I use a heat torch to soften the seal and remove the airtube I might also soften the threads . any suggestions what would be best to remove the seal . The seal is so tight and hard over the years .
These seals get incredibly hard, think bakelite…. If you are not keen to use heat, the next best option,as has been described, is to use a hard and sharp prick…… Once you get the first few crack in the hardened seal, it gets easier and you can nibble away until all the cracked pieces are removed from the joint and you can get movement between the pump tube and sealing cap. Good Luck, Best Regards, Kerophile.
I finally managed to remove the inner air tube . Soaked it with oil and lubricant overnight Then picked some of the old seal out using a needle . Then heated up the old seal and picked all out as it crumbled away . After that I sprayed more lubricant into where the seal was and some oil . After 2 hours I tied heavy fishing line around the neck of the air tube and wiggled it out . There are some pinholes in the tube so I will either use steel putty or solder the holes . Then I will replace the air pipe pip seal and then try to find a replacement seal for the neck of the air pipe
@Jimmy hayes Hi Jimmy, the pump tube with those nasty pin holes is a point of alert for safety. A return of gasoline into the pump tube is extremely dangerous! The only solution I suggest is to silver solder the pin holes, for the most effective and solid repair, avoid anything else. Please once repaired test the tube for any small leak before to put it back into operation. A friendly suggestion: I would look for a good spare pump tube to replace it completely, I am sure some members here could have one. Nicola
After silver soldering the pin holes the second point of importance is the right NRV pip or seating. There are 2 types of NRV assemblies in Enders pumps. One with a pip that is slightly larger than used in the Swedish camp stoves and the other one doesn't use a pip but a seating. I managed to repair some Enders stoves with these parts from Chaowars Kocherteile Laden. Make sure you use the correct size NRV pip or seating. Since this is the only barrier between you and the highly flammable fuel.
@LoveFire I have noticed the NRV pip is similar to Swedish stoves and I’m on the search for some replacement pips . The old NRV pip is similar also to pressure lanterns so I see also if can find . hopefully someone here in the group may have some spares for sale .
@Nicola Francesco Elia , hello thanks for the message regarding the Air / pump tube . I have tried steel putty to fill the holes seems solid hard and I have smooth holes out . Tomorrow I will test the tube for any leaks . Hopefully it will work . I’m still searching online for spare pump tube but without any luck. im also searching for NRV pip replacements and tube replacement seal . If I am unsuccessful in finding parts I think I sell the stove as it is . I honestly prefer Swedish stoves such as 96 , 97 , 100 , etc etc as easy to pick up parts
