enen Posted January 11 Share Posted January 11 HI I have a 584 . I assumed it had a D206 engine I bought a new hose that connects the coolant rail on the right side of the engine with the thermostat housing. I got a 2" in 2" out. my engine needs 1.5" x 2" Case dealer said he correct part(1.5" x 2") is for a d239. Im unsure. I cant see any obvious numbers on the block How can I tell a D206 from a D239? Thank you Quote Link to comment Share on other sites More sharing options...
ksfarmdude Posted January 11 Share Posted January 11 those are neuss engines in those My hydro 84 has engine size stamped in the block near the engine serial number But a 584 engine is factory 206 size Quote Link to comment Share on other sites More sharing options...

Farmall Doctor Posted January 11 Share Posted January 11 Case dealers only sell construction equipment… they might have a hard time finding it. What part number did they give you? Quote Link to comment Share on other sites More sharing options...
enen Posted January 11 Author Share Posted January 11 the wrong part was 3144028R1 The part they claim is correct is 3132144R1 I'll check the block for the model number. Thank you Quote Link to comment Share on other sites More sharing options...
Matt Kirsch Posted January 11 Share Posted January 11 If you can't find any numbers, the only other option is to pull the head and measure the bore and stroke. Most of us understood you meant CaseIH when you said Case. Quote Link to comment Share on other sites More sharing options...
ksfarmdude Posted January 11 Share Posted January 11 Since you have a loader on it that will make it harder to see also Quote Link to comment Share on other sites More sharing options...
Farmall Doctor Posted January 11 Share Posted January 11 That engine has the 3055255R1 water manifold on it with 4 head ports, which were used on some D239 engines. D206 engines used a 2 port manifold 3218034R1. Someone may have changed it... Or it's a real 239. Quote Link to comment Share on other sites More sharing options...
oldiron29 Posted January 11 Share Posted January 11 I had thought someone told me 206 and 239 used same head gasket? if so could a 239 head be put on a 206? Or would water tube be interchangeable? Quote Link to comment Share on other sites More sharing options...

When the 2 port one is used, there are 2 delete plates bolted to the side of the head at the rear. 1 Quote Link to comment Share on other sites More sharing options...

Could the engine have been fitted with a different manifold if the tractor was ordered for a specialist application or the engine has been changed for a D206 from a specialist use application? 🤷🏻♂️🤷🏻♂️🤷🏻♂️ Quote Link to comment Share on other sites More sharing options...
enen Posted January 13 Author Share Posted January 13 the loader does make access tough There is a boss on the block to the rear of the oil filter I may have to sand blast it to see it properly but looked like 39DT20105439 No sign of a engine displacement cast into the block Does this fit the pattern of engine serial numbers?

Farmall Doctor Posted January 13 Share Posted January 13 Scrape the crap off of it to reveal the “2” in “239dt” 1 Quote Link to comment Share on other sites More sharing options...

enen Posted January 14 Author Share Posted January 14 yup, 239DT. This is how the serial numbers work on these Nuess engines? I went to the local CaseIH ag dealer and spoke with the old guy working there. He said all the 584's he's seen had 239 engines. This seems to go against everything ive read online. 1 Quote Link to comment Share on other sites More sharing options...

My brother has an IH 474 with D-206 and I was using it yesterday and it has a 4 port manifold, he also has a CIH 3230 with D-206 but it has a loader on it and it was parked in a different shed and I didn't go look at it. I would try to measure the block from the top of the oil pan to the bottom of the head, D-206 block is 16.70" vs D-239 is 18.08". Quote Link to comment Share on other sites More sharing options...

A DT 239 and a DT 246 are the same stroke , 206 is shorter stroke all my tractor data sites say that's what a 584 used for an engine was a 206 Quote Link to comment Share on other sites More sharing options...

enen Posted January 16 Author Share Posted January 16 I measured the block, it is a 239. I guess im lucky? lol Thanks again for all the help! 1 Quote Link to comment Share on other sites More sharing options...
jimb2 Posted January 16 Share Posted January 16 The D-206 is a good engine as well, uses less fuel than D-239 but has less lower end torque than D-239 because of shorter stroke. 1 Quote Link to comment Share on other sites More sharing options...
