Looking for pictures of early 60's Magic Chef oven Pilot assembly

Hello All,

As of this moment, the last component of the last system that needs to
be fixed in our '63 Avion T-20 is the Harper-Wyman model 58 pilot
asembly in the Magic Chef oven.
Ive been hoarding parts for it for the last 15 months, and finaly found
the last piece yesterday, which was a length of 1/8" copper tubing for
the gas feed to constant pilot, at a local Ace Hardware.
If it sounds like Im making a big deal of this, its because ive tried
every source I could think of for 1/8" tubing for the last 6 months.
I dont know how long this piece was sitting there, but it left a
footprint in the dust.

So now that I have all the pieces, I need to know how they go together.
I have a schematic of how it pieces together from the Silver Avion site.
http://silveravion.com/downloads/maintenance/manuals/range_oven/Harper%
20temp%20control.pdf

But have no idea of how it physicaly goes together since the pilot
assembly was missing when I got the trailer.

Is the pilot assembly supported only by the 3 tubes? (2 gas tubes and a
capilary) or is there another bracket just for the pilot assembly that
Im missing.

If anyone has a pic or two of a early 60s Magic Chef with the Harper-
Wyman 58 Series safety controll and would like to share, you would have
the overwhelming gratitude of a man whose inhaled way to much propane
fumes while figuring out the gas system.


Thanks,
Dave '63 T-20

Dave, there should be a bracket to screw the pilot assembly to. There is a hole in the center of the pilot assy. There usually is a screw that goes thru there and attaches to a bracket. I don't have a pic at the moment but I can get one maybe tomorrow.

There does seem to be something missing down there.
I have the burner and bracket, and the plate that appears to go over the burner.
But thiers a lip on the bracket that holds the valve and it has wear marks like something used to be on it, and brackets low on each side of the oven.
If I knew the distance and orientation that the pilot should be from the burner, I could probably fabricate a bracket out of some galvanized sheet metal.
I would assume that if the pilot was to far away, it wouldnt ignite the main burner before the oven filled with gas. If its to close then the main burner would heat the cap tube and would never shut off.

Got a lot to learn still.......

Hey Thanks Chris,
That gets me 3/4 of the way there.
The innards on mine are set up a little differently, with a cast iron burner that goes croswise in the oven. (I.E. parralell with the door).
I havent found any extra holes in the burner or the flame spreader, but this lets me know that there is supposed to be a bracket there and the pilot isnt supposed to be a-swinging in the breeze.

I think I have enough info now to fabricate a bracket and rivet it to the flame spreader.

Thanks!
Dave.

No Problem Dave. I do have another range in the garage. It is tucked away(I have to move a car to get at it). It may have the cast iron burner. The oven is doa(the safety valve in the back is shot) I will get it out and have a look see either tomorrow or on the 4th. I'll get some pics of that for you.

Heres the beastie that Im dealing with, a Magic Chef Model # CF880.
It looks a lot like a picture of a Princess stove from the same year, I dont know if they where re-branded, or if its just a coincidence.
I do have the stove knobs, but keep them off because the oven doesnt have a main valve (yet) and I have a 2 and 4 year old and and we all know how 4 year olds loooooove knobs

So the main mystery is that I havent found any extra holes for a bracket to go into. Theres some discoloration in the rust in the underside of the flame spreader that seem to match up to the dimensions of the pilot assembly, but that orientation doesnt match up to the oreintation provided by the capillary tube.
The cap tube has a strange bend in it, like it was supposed to go around something. Its not pliable at all so Im assuming that that bend was put there on purpose.
This also assumes that this was the origional safety valve for the oven.

Im thinking my best bet is to screw a 1" steel standoff into a new hole in the flame spreader to hold the pilot.

Cheers,
Dave.

Interesting. It makes sense now. You have a much bigger range than I do. Hence the larger burner assembly. I think you are on the right track. I would fabricate a mount. From my pics you can see about how close it needs to be.

I wouldn't bend that cap tube at all if you can help it. They tend to get fragile, don't ask .

It seems strange that there are no holes in the burner bottom or the heat shield. I can see where the pilot was, however.

Good luck. Let us know how it turns out.
