Wanted: D17 diesel oval body Nelson Muffler

Looking for a nice oval Nelson muffler for my D17D series 3. NOS or very nice used. Part No. 237290 and a series 4 would be the same.
Thanks!

The muffler is great I bought one for my D17 series 3 gas could not believe the difference been a long time since I had the original Nelson on it

I'd like one for my series 4 diesel as well, but I'm guessing he needs a minimum order amount to proceed with getting them made.  They are going to be expensive because of the smaller demand, but will be worth it in the long run, so perhaps anyone that is at all interested in one for the diesels should let him know, maybe we can still get some made up.  I've gotten 3 mufflers from him for my D15, D14 and 170 gas, and they are all good quality and am pleased with all of them, but it's got to be practical for Alex as well, he's been good to me when I've gotten other parts from him,  

Maybe Alex can 'step up' to making mufflers too? and make them out of stainless steel or other kind of suitable metal that won't rust or deteriorate over time.  

I have. Simply cost prohibitive to build them at the moment. The diesel production numbers are so much lower than the gas, which doesn’t help either.

I’m fine with a nice used one though.

Is there any reason you couldn't use a 180/185 muffler, which Alex has in stock. The agco book shows the same number for the inlet clamp on d17 diesel and 180/185 so the inlet end of the 185 muffler would be the same as d17 diesel. The muffler body may be longer(not sure) and the outlet pipe little bigger and maybe longer but I would think it would work just fine.A little more open and breath better.

Thanks gentlemen - I wasn’t aware of that as an option - that may definitely be the way to go here!

Dr is correct on the 185 muffler dimensions. But seems to me I had DCAC measure his hole in the hood for a D17d muffler last year and the 185 muffler won't fit through the hood. The D17d/15d muffler has 3"x7" oval body dimensions. So for those who don't mind cutting the hole larger in the hood, it would work as I can confirm the inlet is the same. The 185 muffler may look overly big, so depending on how it looks, maybe cut down the outlet pipe height.

OK. The 185 muffler does fit a gas series 3 and 4  D-17, and also pretty sure the D-19 gassers are the same too.  I'm surprised that it fits the gas models and the diesel is a smaller body.

Not a wrong key. I use the 180/185 mufflers on D-17 3 & 4 and 170 gas tractors. First one was my Dad's series 4 back in 1969 or 1970. I have to use a piece of pipe to adapt the larger inlet to the gas manifold pipe. They sound better, exhaust up higher and surely (in the mind of a 16 yr old ) had more POWER !!  I also had engine speed/governor action so full load was 1900 RPM instead of 1650 RPM, so the larger outlet had to help reduce exhaust temps when working it hard.

To update everyone on the D15/D17 diesel oval muffler, according to Nelson there is no 3"x7" oval body muffler in production or in their current catalog. So there will be no alternative Nelson available as ordering new ones is insanely cost prohibitive. Only option is to cut hole in hood larger or to space the 4.25x9" oval above the hood.
