It really is confusing!

 

The 678 had a turbo'd IH DT239 3.9L producing 62kW@2400rpm and 285 Nm torque at 1600rpm thus 83 horsepower. Compression ratio 12:1

 

Now tractordata says the 84 hydro engine (IH D246 4.0L) produces 65 hp but other info from this unopenable link (https://www.google.co.uk/search?q=Bruunett+Mini+578+F+forwarder.+Dimensions+and+ergonomics+%28Bruun+System+AB,+Filipstad,+Sweden%29:+The+forwarder+is+powered+by+a+4-cyl.+4030+cm3,+56+kW+engine+and+is+fitted+with+500+-+22.5+tyres+all+round.+The+cab+dimensions,+seat+and+controls+characteristics,&ie=utf-8&oe=utf-8&gws_rd=cr&ei=0tvQVcC7Oomta8TelsAF)

 

says it produces 56kW thus 75 horsepower!

 

I'm guessing the atmo D239s and D246s came in various power outputs. The Bruunett 578 had the skid unit from the 84 hydro but that link throws doubt on it...

Parts sorry; JASPW has a few, not needed any others!

 

If I had nothing better to do I'd do a nut and bolt restoration but can't see that ever happening; heater and cab comfort parts probably a non starter. IH parts dead easy. Base unit transmission - clock ticking no doubt; have to have them made I guess.

I see. Remember them from the 80's, seemed to have few transmission problems from what i remember,.

Apparently so but I have had no issues with mine with the exception of bogie gear repairs from the ol failed bearing; I check those bearings very regularly.

Fair play to you for keeping the old girl going, and still able to do a days work, the beauty of being a owner driver!!,, most new machines are hammered in their early life by the drivers that bragg about putting a thousand tonne a week on roadside that ends up sitting there for months drying out.,

Thanks. Saw a load of that driving through the borders. FC sites maybe? It was all over the place.

My 578 has a dt239 engine with the turbo removed.

TDC I never taken any notice of this before but just seen in the brochure it has a d239 engine which im assuming is the nuess d239?

Same engine as in my 684 tractor. They are quite respected for the hydraulic side given the age etc. How do you find the hydraulic system?

The turbo version was mainly used in the crawlers. Uses a slightly different diesel pump to also compensate.

I really should read thru all the post....

The d246 is used in the 784/785 855 etc tractors.

 

If your unsure what engine it is you have it is stamped in raised letters on the side of the engine block quite visibly if you look.
