    I have acquired this Aladdin 1A, which the first and only Aladdin I have. Most of the other numerous lanterns are Coleman and Tilleys. This is in such nice condition that I am afraid of damaging it but would really love to see this running. I have pretty much got the hang of fixing Colemans and Tilleys (which are really easy). So this lantern has a good clean generator with working cleaner tip and the rest of it looks ready to roll. However it would appear that the NRV is completely blocked as I can't get a bar of pressure in the tank, I guess it will have to be removed cleaned in Carb cleaner etc. How the hell do I get this sucker out without wrecking it. At the moment I have carb cleaner soaking in the pump tube but as of today doesn't seem to have made a jot of difference. HELP! Aladdin 1A.JPG

    Welcome to CPL @David Cully

    That Aladdin is in excellent condition congratulations

    This post should help you. The NRV removal tool can be made from a large bolt or steel bar with a 5mm wide x 5mm beep cut in the end.

    Thank you so much. The NRV set up looks similar to the Tilley with the spring and pip arrangement. If I can get it out this should be a goer.

    Yes cost NZ$30.00 which I thought was a really good price. Of course it has had a clean and polish. Unfortunately came without a globe or bail. Bail I can make but I hear that the globes are very hard to come by.

    OK. Made an Aladdin NRV removal tool using the 5mm x 5mm formula which worked like a charm. The tube containing the spring etc. was blocked solid so have cleaned and polished. The "pip" had disintegrated and as I do not have one tried a substitute by cutting down a Tilley one also pulled out the spring a little. Screwed it all back up tight (but not too tight) and all the air that was going in came straight back up the pump tube. I can't see a washer in the bottom of the pump tube. Should there be one? I am used to Colemans and generally they don't need one. I have water tested to make sure any air that is going in is not leaking out somewhere else. It isn't. Maybe my makeshift "pip" is a dud or maybe the whole thing insn't sealed into the pump tube. Any suggestions would be most welcome. Aladdin NRV.JPG

    You can check the sealing efficacy of the complete NRV by blowing or passing air through it in reverse direction. Do it with with a low pressure compressed air line or simply by lung pressure :).
    Preferably the latter:p:- to better simulate that it should not require high fount pressure to ensure the pip seating and sealing.
    It should not pass air in the reverse direction. If it does, then either the pip is not properly seating, material too hard or the spring-loaded pip holder being stucked in the NRV tube.

    Good idea, I will try that tomorrow. I have spent most of the day trying to fix this and have now stopped as when I get tired I tend to rush and wreck which I do not want to do with this one.

    There is usually some sort of seal between the NRV's and the bottom of the pump tube, often it's a lead washer but rubber also works.

    David, Henry is right, there is usually a seal and lead was the most common material. However many members cut their own out of second hand bottles made from HDPE plastic.
