Recommended Posts

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

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

Should be by where oil filter housing bolts to block

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?

Water manifolds are interchangeable. When the 2 port one is used, there are 2 delete plates bolted to the side of the head at the rear.

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.

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?

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?

Scrape the crap off of it to reveal the “2” in “239dt”

Guess I never read block numbers, but is 239DT a turbo block or was that such a thing on those?

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.

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".

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

574s were all D239, that is likely what he meant. The 474 was D206. 584 was D206 and 484 D179.

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.
