Spark Plug for Hunter heater

[mutt_r]

Hi folks,

It is cold outside and I have here a multifuel space heater with a spark plug defect. The heater was made by Hunter, NSN 4520-00-114-1055.

The spark plug must be replaced.

My first thought was, to search for the part number. I tried to find the manual for the heater online by using the NSN and I had no luck.

Who knows the P/N of the spark plug and where I can buy one or two?

Thank you very much in advance.

Richard

Is there a TM listed on the data plate?

I have a tree full of heater TM's.

Ah, the elusive UH68D heater. No wonder you can not find a TM. I cant find it in my heater stuff. There just seems to be not info. The NSN came out in 1968, so its not a new heater. One other thing I might be able to try is, what did it come out of? What equipment did it come out of?

Have found the TM number. Went back into the OL,OLD trailer TM's, because I remember working on these heaters. Its listed in the trailer referance listing as: TM 5-4520-233-14 for the operators TM. The parts TM should be -24P. But find one? Not yet.

Hello Guy,

Good to know it is Winter time and you have the time to enter this thread.

The heater is stand alone. So I assume it lost the relation to any trailer or whatever it was ever mounted.

The -14 & -24P I just found on ebay. But it will take weeks to have them here in my hands. And will the spark plug listed in there be available?

I hope you have the -24P which might shorten the way a lot.

Thanks,
Richard

Richard!

Did not look at the Icon at the top. No, do not have them. I too found them in E-Bay, was just writing to tell you that. I will ask someone who might know. I only found the TM number by looking at every expando van TM in my collection, and looking at the appendix A, References. The reason they are not in my collection is because the are SO OLD. Old as dirt. Is the spark plug missing? Is there no part number on it?

 

[mutt_r]

Guy,

The spark plug is there and the heater is working, but it looks like the spark plug will quit service soon.

There is a number on it, but I am not sure. Something like
S1-140-S0
81-140-80
61-140-60

 

[Guyfang]

I tried all those numbers. No go. You sure there is nothing else?

 

[mutt_r]

Guy,

I'll check. It is dark outside

 

[Guyfang]

How about some pictures? Champion plug?

Yeah, 00:20

Its to late to explain how I got the number. Maybe in the morning!

Guy, the spark plug is marked as Auburn S1-140-SG

 

[Guyfang]

May be not the right one. But maybe it works. The above listed came right out of the TM. I found the TM in Google Books. Did not down load it, as I have no idea how, but did look through the TM until I found this info.

 

[mutt_r]

Guy, that thing on ebay looks like 100% perfect. Thank you very much and enjoy today's coffee break with your family after doing this investigation. Thank you very, very much.

 

[mutt_r]

Hi Guy,

It looked perfect, was ordered, arrived last week. And it does not fit

The length of the spark is too short and the thread does not fit.

Back to the beginning ... Who is Sherlock, who is Watson?

Regards,
Richard

 

[Guyfang]

Look like this?

 

[mutt_r]

Guy, finally it went well with the spark plug I ordered. No idea what caused the problem on my friends side. But it is in now.

Again, thank you very much for your help.

Next time being in Franken, we should have a cup of coffee again (or a glass of wine or a nice Bavarian beer).

 

[Guyfang]

Beer! keeps Covid away!!

 

[mutt_r]

When I am not wrong, Bavarian beer has less alcohol than Bavarian vine Perhaps I should bring some Northern German beer

Okay, this is a forum about the green virus and not about the taste of the world. CU.
