How to loosen an air intake tube

[Redgloves]

Hi,

Working on a 1968 Sears 220F lantern. Found instructions on the old comean parts website how to disassemble the lantern. Have progressed to the part of trying to loosen the air intake tube.

What suggestions are there to loose the tube?

Easier to ask before I ruin something.

I have found soaking the screw and tube with a good penetrating oil helps to make the removal easier. Just let it work for a few hours.
Section 3a and 3b shows the removal. Also the coffee can lid trick sounds like a great idea.

The little screw was extremely easy to remove. Dripped penetrating oil onto the air intake valve and what ever the connection is called.

Now off to the local home improvement store to invest in the remaining tools I don't have.

If you can find one the, 220B950 Coleman wrench is really handy for loosening the nut at the base of the burner assy. Before I got the wrench, I had good luck using a tappet wrench as they are thinner than a typical wrench. The Coleman wrench is the real deal though, has a little angle built into it. Doug

Either I am not explaining completely, or don't understand what Doug is saying.

The problem is the tube will not move. Totally stuck. The photo is from Coleman instructions. The nut on the other short piece is loose and the small crew holding the tube has been removed.

If penetrating oil did not loosen it try heating the casting holding the tube.
It should unscrew using just the force from your hands. It might help to find some way to stop the fount from spinning while you try.

Yup, what he said.

I had the same issue with my Sears 220 lantern. I ended up using a pair of vice grips an grabbing the side of the screw. It came right loose. I tried several screw drivers with no luck.

Leave the piece on top of the intake tube on (the piece that the mantle tubes screw into). Clamp some vise grips down near the bottom of the tube (careful, don't crush the tube) and use the top as added leverage. This'll probably take two people to do. One to hold the tank and the other to unscrew the air tube.

I had this happen with one of my rebuilds, also. Didn't know if the thing was going to come loose or twist the air tube in half. It cracked loose.............. whew!!

Sorry, I thought you couldn't remove the nut. PB blaster is great penetrating oil. I just took apart an absolute rust bucket today using PB with no problems, 'cept the vent stem was really corroded and I twisted it off. It was rusted so bad that no threads were left to screw the vent nut on with. Had to drill and tap it for a new piece. Doug
