Speed Queen Gas Valve Stuck

[fordiesel69]

Video here:


Gas valves are supposed to be dual redundant, so when they fail, they fail closed. Is there a reason why this valve still works fine but leaks? Inlet gas pressure is 7" WC, and all electrical sources have been removed to rule out a problem there.

A new one is over $150

I wonder if this can be warrnaty even though it is an 07 model. This is not a normal failure mode, and can be extremely dangerous.

Just the nature of gas.

That is the number one reason all gas equipment fails more often than electric.

Moisture and junk in the gas.

Both of the valves have been erroded over time with the moisture that's in gas.
I suppose that would be the reason gas is scented,...

And you know what they say.

If you are going to play the game, (collecting or similair);
You will have to buy the tools (parts in our case).

Quit beating on that thing, and get it fixed,...
We want you around a little longer, young one!

Good Luck,

Not the popular choice, but at $194 for a new valve, I tore this down and found the stems to have a rubber pad on the bottom, it looked good. The aluminum sealing surface machined into the valve was corroded, so I cleaned it with 600 grit, and some bar keepers friend on a scotch bright. I then cleaned it with 91% alcohol, and blew the port out in case any material got in there. It seems ok. Will be shutting the gas supply off until I can absolutly verify it is fixed. I will say the internal build of this valve is complete junk and speed queen could do better. very crappy design inside.

You are spot on...Needle and Seat.

That's always most common; The needle material is designed to "squish" into any cavities that the seat may have acquired over time, and aslo the material is suppose to absorb any small particles that a perfect seat would not allow to seal with compression.

I have tore many apart, too, but you know, in this country, I can't exactly tell you Rip open the gas valve and plunder around...ya' know??

Same exact thing with GM's Rochester Quadrajet...In the early days the needle was brass...later changed to Viton, and helped with the horrendous reputation of that carb. But's its still my favorite carb for hot rodding and modin'.

Good Luck Man,

Post Script:
My first tractor was a 69 Ford 3000 diesel...about 40 horse. Still have till this day.
Your name brought back Mammories, I mean Memories...:_)

Is this a vintage machine with the gas works on top under a small door?

LaVidaBoem,

My username was developed because my first vehicle was a 1986 Ford-F250 with a 6.9L Diesel. Forddiesel69 was taken on the forum I tried to join, so I combined the "d" and it worked.

In terms of what you can suggest online, absolutly you can even if it is dangerous. A disclaimer would also work, Basically unless you kill someone and post admit it online, the feds will not pull your IP address.

I have not allowed enought time to go by to see if this is fixed, but so far so good.

alr2903,

This is not a vintage dryer, I was recording it from the top when I had the entire unit apart to de-lint the interior. It was a blessing I found this problem during the de-linting, or this could have been a disaster.

OK...

Thanks man for the heads-up...

I almost knew the 69 was a Ford...you are too young to have been around in '69...

I think I will refrain from the dangerous stuff for a while, but maybe I will pop down and tell you "here" what I have done.

That bearing in your drum with the enlongated hole...no prob.

Cause I don't think you are going to get them to give you a drum, unless they follow this forum and think it would be "good for biz".

With the tranny assembled to the drum ON THE BENCH, Mark where the bearing flange rest and against the housing.

Take apart, and lay one of the flanges back into your scribe marks, and braze, not weld,...will outlast the rest of the screaming queen.
The other night when you posted, a man had 2 bearings on EPray from Ripon for this, the other one for the milkstool...only 10 bucks each...not bad.

Thanks, and Good Luck,
LaVidaBoem

It helped but did not fix the problem. Another cleaning and more importantly I tightened the springs on the plungers. I listened to my other speed queen and the plungers really made a nice harsh noise on power off. This did not. A quick stretch of the springs and now all is good. I put the cover back on and this morning not even a wiff of gas anywhere.
