D6R Track Wear

[Birken Vogt]

It is an S6T prefix, built Dec. 2013, a third world version..has C9 motor at tier2, so is essentially a 6T vintage tractor without scr/dpf etc.
I haven’t been able to track down a spec sheet for it so if anyone has any info on the series I would be keen to see it.

Where was it originally ordered/delivered seeing as it was a third world version?

What type fuel injection system did they use on a tier 2 motor built in 2013?

Any aftertreatment (DOC) at all or straight out the muffler? EGR?

 

[Nige]

Without a Serial Number my first thought would be that if it was built for export it was likely built in Brazil although the engine could have originally come out of the US, probably the Cat Seguin (TX) plant.

Fuel system appears to be HEUI.
No after-treatment. Exhaust goes straight from the turbo out of the stack.

As I recall Tier 2 did not require any after treatment at all. Many manufacturers claimed special injection functions, electronic controls, and maybe some internal changes to pistons and heads. I don't recall a D6R with anything special either.

I was at a conference in the early 2000s and there were sessions with manufactures reps. I had a client who was bringing in gray market machines to the US who wanted to know if they could be updated for use in the US. Every brand said that would not be possible at all unless the engine already conformed to EPA rules. My next question was "do any of you makers build engines for other countries that do not comply with US EPA rules?" Not a one of them would answer the question. Later on I spoke to an equipment manufacturer rep and I made the comment that the engine people were not at all concerned about emissions. They were only concerned with the money they could make. He told me that was true but since I asked the question in front of everyone in the auditorium, the makers reps would likely never be back to that conference in the same capacity again. I hear that was the case.

Serial no. Is S6T00779, possibly built in Japan but definitely delivered new to Indonesia.
No after treatment and, I’ve been told, a lot less electronics on transmission, etc.

 

[Nige]

Engine was built in Texas, tractor in Brazil. Not unusual for a machine being shipped to an LDC (Less-Developed Country)

 

[John C.]

But does the engine comply with US EPA for that date in time? I believe it will say in SIS.

 

[Nige]

No it will not. It will have a sticker on the valve cover saying something like “Export only. This engine does not comply with US emissions regulations at the time of manufacture. Final destination must be outside the US. This engine may not be re-imported into the US.”

I can tell you that last sentence caused Reman loads of grief about getting cores back to Corinth from overseas. I’m not sure how it was solved TBH, all I know is that it was.

When in Peoria last year on the Cat tours we spent 4 hours in the assembly building for the D6, D7, D9, D10, and D11. The amount of engine pollution trim went from nothing with a simple straight unencumbered exhaust stack to what looked like 100 wires running around the engine and stack. It was explained to us that it all depended on where the machine was headed to around the world. I had thought the D9 was no longer being made but they still make them for export only.

 

[Birken Vogt]

I find it a little strange that they would have HEUI on an export model and not PLN or HPCR or MUI for reduced fragility.

But maybe they figured there is no place to mount an injection pump and no easy way to get a third cam lobe/pushrod/rocker. Or maybe they just don't care about what I presume is small volume for the export market and just kept using what they had used in the past when it was legal in the states to avoid redesigning the thing.

 

[Queenslander]

I’ve seen a number of similar tractors, but with S6X prefix, advertised in Europe.
Seem to share the same instrument panel, tiller and park brake control.
These pics are from a tractor in the Netherlands.

...... Or maybe they just don't care about what I presume is small volume for the export market and just kept using what they had used in the past when it was legal in the states to avoid redesigning the thing.

I think you hit the nail right on the head about not wanting to go to the expense of engine redesign, but don't be under any illusions about the LDC market being "small", it ain't.........

 

[Nige]

Found an engine here on site with an Export sticker on it. Not exactly the one I remember from years ago (haven't looked for one since TBH) but it gives you the idea.

 

[Queenslander]

It’s taken some time but we finally have the tractor set up the way we need it.
Ended up replacing all of the undercarriage, except for plates, and re sleeved and sealed cannons.
Couldn’t stretch the budget far enough for genuine but aftermarket will have the machine earning it’s keep for a while.

 

[Queenslander]

Tractor has been running great.
I haven’t been able to establish whether it is, in fact, the Tier 2 motor at 195 net hp or Tier 3 at 200.
Either way it is plenty for a D6, although with the canopy and heavy rippers it weighs in at 25 tonnes, so most of the power does get to the ground.
Runs very cool, but other day while helping to fight a fire the temp gauge suddenly shot right up to red.
Wasn’t in a position to stop for long except to check that the motor wasn’t hot and kept going.
Now the gauge goes straight to red as soon as key is turned, along with the yellow exclamation warning.
It has the same instrument panel as in the pic above, similar to M series grader.
Not sure if codes can be read from this panel or if it may need ET.
Just wondering if these symptoms sound like a failed temp sender/sensor?

The tiller screams d6h to me.

 

[Cmark]

Here's the emissions data.

 

[DB2]

Did you sort the issue with the temp gauge? That protector over the tractor looks sharp. Like the looks of the rake as well. Much different than we see in North America.

 

[Queenslander]

I would say exactly the same Tyler.
That’s one of the things that I like about the machine... mechanical linkages to the transmission/steering, no electronics.

Here's the emissions data.

Thanks for that information Cmark, I guess it confirms that it is this tractor.

Haven’t sorted the gauge yet, unless someone can suggest a a better idea, I’ll probably try a new sensor first.
Unfortunately, we haven’t been able to use the rake as much as we would like.
Because it is so dry, raking tears out too much valuable pasture grass and starts fires.

 

[Nige]

Can’t remember if you posted the S/N but that would get you the electrical Schematic. It might be advisable to check the wiring first. The clue is in the fact that the gauge pegged and the light came on instantaneously rather than readings going off over a period of time. I’d be thinking cut wire, but I may be wrong.

 

[Queenslander]

Hmmm....that makes sense, I was bouncing through some rock when it happened.
I’ll send you a pm.
