And here are some photos of the device I used to pressure test the assembly.

new question - old thread

My stove burner valves on my Tappan Mity Mite LP stove (1963 Airstream) show a very minor detectable leak with one of those very sensitive electronic gas sniffers.

Here is a picture of one of the 4 valves. They look different than the previously posted picture,

My question is how do you disassemble to clean and lubricate with valve grease???

It is probably simple, but it is not obvious to me.

Thanks,

Thanks Gary.

I was hoping to do this myself. Can anyone offer advise on how to disassemble the valve?

Mike

Can you post more and better pictures?

I can't see much.

In general these gas valves are of the tapered plug design. There is a tapered core with a slot or hole in the middle and a handle attached at the top (wide) end. I've seen two designs, one uses a retainer mechanism at the bottom end, either a C clip and spring or a locknut, the other has a retainer mechanism at the top made of a clip that screws into the valve body.

Either way, with the gas supply shut off, you remove the retainer clip or nut (as the case may be), and pull and twist the valve core out by the handle. Clean, grease, reassemble, cook.

Here are better pictures of my stove top gas valves for my 1963 Tappan Mity Mite range.

The is a hole in the collar of the valve nearest the knob. I don't see what its purpose is. I think I should unscrew this collar and the internal valve will just come out. But before I do something that causes unrepairable damage, I need some technical advise on how to dissasemble these valves.

I hope someone can give me a hand.

Thanks,

My newly aquired '63 has a Tappan...I'll try to look. I'm thinkin there is a pin that you push out of that hole when it's turned to the right place - then the spring loaded guts will come out.

Well, I've discovered that the front end of the valve body (the end nearest the burner knob) unscrews. I haven'tcompletely removed one yet until I understand what is going to pop out. Also, the front panel is not removeable because one of the screws that secures it to the range is under the burner valve manifold pipe. It would be a real pain to remove the manifold.

Does anyone know what the small hole in the collar is for? There is not a pin in the hole. Was it just to insert a small rod to tighten the collar on the valve body?

I ran across a DIY website that had a remedy for a leaking stove burner valve. Rather than taking the valve apart this service tech recommended using 3 in 1 oil rather than valve salve. In fact, he strongly discouraged disassembling valves.

Here is what he recommended:
1. Use a 3/8" rubber tube and insert it over the orifice nipple shown on the right of the above photo.
2. close the gas line shut off to the stove.
3. put several drops of light weight oil down the rubber tube.
4. While gently pushing and pulling of the burner knob to unseat the valve, blow (with your breath) through the tube to inject the oil into the valve.
5. Making sure no flames are lit, turn on the gas briefly to expel any excess oil from the line.

I had one valve that had a very minor leak detectable with one of those electronic sniffers. After this procedure....... no more leak.

This was sure easier than taking the stove apart to be able to take the valves apart.

I'll keep you posted whether this fix lasts a week, a month, or a year or more. So far, so good.

I tried Grand Masters' remedy on a sticky burner valve that was blowing gas out the front of the stove. After removing the knob I noticed alot of dried crud on the valve stem. I cleaned it off as best I could with the help of a toothpick and I lubricated the stem with 3-1 oil. The knob now pushes in and out freely with no more flame coming through the front panel.

Great tips here, After looking all over Columbus finally found gas valve core grease. Quite pricey but money well spent. As for any other vintage owners this should really be a preventive maintenence routine. My stove valves and shutoffs were in need of some attention.
Thanks Robert

The 3-in-1 oil fix for leaky stove burner valves is still leak free. Six months.
