here is the first pic i have seen of the new D11T i have herd that they will present it next year........

Looks like a big, mean machine! A real winner.

[Dozerboy]

I want one:bouncegri

[9420pullpan]

i would like to know the new specs. i know that they put a new engine in it.. i wonder if it has more power...... i agree with dozerboy i want one!!

[Tigerotor77W]

I was under the impression that the D11T was going to be postponed...

the first-run literature that I picked up still says the D11T retains the 3508B engine, though, again, I'm not sure if this to change.

I heard that the 11T was gonna be postphoned as well until they could get the new Teir III engine for it... something like a C17:confused: ... I really don't know my engines, so I'm not sure.

I'll take 2

[D10N]

We were told that the 11T is a no go until the Tier III Acert engine comes online as well. Luckily we just scored a couple of new 11R's.

[bozoloaderman]

We have a new D11 arriving in the next week or so. I was under the impression it was going to be the "R" series, but the Finning mechanic that was called out to work on our 994F the other night said the new machine will be the "T" series. Makes me wonder if we are getting another field follow machine, like the 994F. We had that before it was officially launched as well. There was all sorts of Finning and Caterpillar personnel on site for the first couple months monitoring it. I will post some pictures when the new machine arrives, we have the blade sitting in the yard already and expect the new 16H and dozer soon.

Some wags at a mine I visited had added an 'I' to the logo of their new D10T...

Haha, what was that all about? (Not liking the machine?)

[Wulf]

Haha, what was that all about? (Not liking the machine?)

No I don't think so... I just think they saw the opportunity for a bit of humor

[Deas Plant]

Hi, Folks.
Actually, that ID 10 T has a valid application, especially in computing but also in many other fields. Many mistakes are "ID10T" mistakes.

You all have a wonderful day. Best wishes. Deas Plant.

[9420pullpan]

i love it!!

[Dozerboy]

Quit post pics of all of this nice equipment, or I'm going to have to quit my job and go work else where.

[royce]

I have had some literature for about a year now on the D11T. As far as I know this model was never put in production, it has the 3508B engine and is more or less a D11R with new operator controls. The recently announced D11T is powered by the Cat C32 V12 ACERT , however it is also rated at the same 850 horsepower as the 3508B The latest information that I have shows that the T weighs the same as the R and Max Drawbar pull is 340.000 pounds , same as the R. The C32 V12 ACERT weighs about 5000 pounds less than the 3508B so there must have been many changes to keep the weight the same. just curious, comments please.

Welcome to Heavy Equipment Forums royce! :drinkup

[EZ TRBO]

I haven't heard much on the new machines comming out but do know that CAT is having a very hard time with the new emmission engines. Guy that has hauled some of our big equipment in the past just got a new Pete(tri-axle tractor, C15, the whole ball of wax) and I asked how he liked it. "Not very well. I wouldn't complain that it doesn't have much power but the fuel milage is awful." He went on to tell me that when he called JXE the service man told him to "get in line". I don't know where this would relate to heavy equipment but thats what I have heard. Dad was saying that any of the new single axel and tandem's they are buying for the highway dept are being ordered without CAT's, due to the truck compaines recomendations. Otherwise great looking machine, should move some dirt. I know some of the older IH guys will love the DUAL STACKS. LOL

-Jim

On the older engines such as a 3508, the first two numbers signifies the displacement in liters (35) and the last two digits represent the number of cylinders (8). The Acert engines just tell the displacement witch happens to be 3 less liters on the new power-plant for the D-11T witch uses the C32 engine. Here is the link to the model on the Cat websitehttp://www.cat.com/cda/layout?m=37840&x=7

[Per Eriksson]

Not correct.

[farm_boy]

On the older engines such as a 3508, the first two numbers signifies the displacement in liters (35) and the last two digits represent the number of cylinders (8).

I beg to differ here.....This line of thinking might hold true for the 3508. It is in fact a 35L (actually 34.5L) and is an 8 cylinder, but this is not true for other Cat engines. If this was the case 3406 and 3408 would both be a 34L engines? The 3406 is a 14.6L I6 and the 3408 is an 18L V8.

[N.CarolinaDozer]

NICE Dozer! :notworthy I wish our company bought some, but the biggest dozers they buy are D9's. It's my dream to run a D11 some day.:(

[Lashlander]

The 3500 is the series. 3508 is a 3500 series engine with 8 cylinders. 3512= 12 cylinders. 3406 is 3400 series with 6 cylinders on and on.

[RollOver Pete]

Hmmmm..:confused:
So a 1693 or a D342 would mean what?
:cool:

[farm_boy]

Was there ever a rhyme or reason for the nominclature of the engines? What did the 3400, 3500 series engines stand for....anything?:beatsme Just currious.

[bigpete]

I agree Dozerboy, a job change or maybe i will start hideing the old 155AX behind a stockpile down the back of the job someplace.Dont they look grand new,

[Lashlander]

Hmmmm..:confused:

:cool:

Hmmm, Don't know. The number system has changed though the years. A 399 was a 300 series engine with 16 cylinders. A 398 had 12 and a 379 had 8. I think all the parts interchanged except the cam, crank and block. The heads covered two cylinders so on the bigger engines there was just more of them. Wheres Tiger or Surfer Joe?

The recently announced D11T is not the one in these pictures. These are of a D11T that I have had literature for over a year but was it never built. The recently announced D11T has a C32 Acert 12 cylinder 31.5 liter engine , replacing the 3508 8 cylinder 34 liter engine used in all previous D11s. There is more black on the recently announced D11T and the Cat and D11T decals have switched their positions on the side of the tractor. The information that I have shows that the weight of the recently announced D11T is the same as the D11R, but the C32 engine is about 5000 pounds lighter than the 3508, so there must be a beefing up of many other components in the recently announced D11T?

I do not agree that Caterpillar is having a hard time with the new emission engines. The new 2007 Cat Acert engines have been an real success story. Unlike the other makes of engines that use cooled EGR that pollutes the engine oil and causes high underhood temperatures, the cat 2007 Acert engines have been virtually trouble free. The large fleets that started using the 2007 Cat Acert engines have also reported better mileage than comparable engines from the other manufacturers. Unlike the cooled EGR systen add on ,used by the other manufacturers , the Cat engines are emgineered correctly for reduced emissions .
To the best of my knowledge, All D11 tractors have always had dual stacks, but you are correct about the IH guys, I remember the IH TD18 and 24's having them, always thought it was a nice feature,of course they were inline stacks being powered by inline 6 cylinder engines with a dual exhaust manifolds.

[royce]

Yes, the numbers that Cat has used for it's many series of engines over the years keeps changing. Now it seems that the "C " prefex is being used .
Examples :

C6.6 C7, C9 ,C11 , c13 , c15, c18 (6 cylinder engines) c27 , c32 (12 cylinder engines) the number is roughly the size of the engines in liters.

The C175 and C280 is the bore size in millimeters , these numbers are followed by another number designating the number of cylinders. example
C175-12 has 12 cylinders. C280-16 has 16 cylinders .

However , in the past Caterpillar used such numbers as: D13000 and D17000 .
The D probably stands for Diesel, the 13000 and 17000, I have no idea what those mean. The D13000 was used in D8 tractors before being replaced by the D342. The D17000 is an interesting engine because it was the first Cat diesel engine that was not designed for and used in any Caterpillar machine.
It was Caterpillar's first V8 engine. It had a 5.75 inch bore and a 8 inch stroke, had individual cylinder heads for each cylinder and developed 160-200 horsepower at 800-1000 RPM.

[RollOver Pete]

Something like this V8 Cat?
:cool:

[dieseldave]

The 17000, 13000, 8800, etc #'s are the hp followed by 00. Ie, the 17000 = 170hp, 13000= 130hp, 8800= 88hp, etc

[royce]

Hi RollOverPete,
Yes, that is a D17000, thanks for the picture.

Hi Dieseldave,
I would say that you are correct that the horsepower with OO added, is how Caterpillar named these engines, probably the horsepower rating of the early production engines, later versions had higher ratings. Learn something every day. Thanks for that infomation.

[RollOver Pete]

Many years ago as a teenager, I got hooked up with a contractor who was the one responsible for bringing me into this business.
He gave a kid a chance and I ran with it.
He did mostly demo jobs and had a 977L, two 980's, 988, 46A and the infamous 2U.
While in Jr. High, I worked with him after school, weekends, basically any chance I could.
This old man also helped me get my CDL in 1983.
I was 16 at the time and was making $15.00 hr.
One of the 980's I ran back then had a 3306 and rippers.
The other 980 which I assumed was the older of the two had a turbo charged Caterpillar V8.
I remember the valve covers seemed huge...almost sticking out past the panels.
I've never seen or heard another Cat 980 like this one.
It had a sound unique to the V8 Cat motor.
Almost a kind of whine which was much different than a turbo sound or the sound of the 3408T.
Would anyone here know or be familiar with the V8 that might have been in that 980?
I never knew where that old 980 went or what happened to it.
I'd like to know more about the V8 that powered it.

A bit off topic now.....bare with me....

I was pretty lucky as a kid.
Guess I was at the right place at the right time.
There were still good people around who would take the time to teach a kid the ropes.
Today, something like this would be unheard of.
Law suits were the last thing on anyones mind back then.
Today, they are a every day occurrence.

Those two old timers from Illinois have since passed long ago.
I still think about them and what they taught me just about every day.
Like I said, they brought me into this business.
They taught me how to do demo and move dirt.
They showed me how to care for your equipment and turn wrenches.
They are the reason I became an Operating Engineer.

I owe much of what I know and have become to those old 980's, that awesome 46A, the huge 988 and 977L with a 4 in 1.
But mostly I owe Richard Henderson, Elmer Drapper and that old 2U I ran in Palm Desert back in the summer of 79.
Thanks guys :drinkup
:cool:

[RollOver Pete]

Oh yeah....
Another thing I remember about that 980 was that it had a f-r selector on the steering column like todays machines.
The difference was that you didn't twist it to change gears like on newer loaders.
To change gears 1-3, there was a lever that came up on the left side of the operators seat.
This may have been one of the first 980's made by Cat.
:cool:

[Deas Plant]

Hi, RollOverPete.
2 VERY good posts. Thank you for sharing. Like you, I owe some people in my past a debt - which I hope I am repaying by teaching others my craft and helping others whom I can't meet face to face with information in forums such as this.

My thanks go specifically to George Walmsley who, in Feb., 1965, gave me a start as a learner operator on a 3T D7 with a cable angle blade, Brian Bairstowe for his efforts in teaching me some of the tricks of the trade with that D7, some of which I still use today, and to 'Richard' (The site language censor won't let me post the abreviated form of 'Richard'. It seems to think I am referring crudely to a male genital organ.) Archer for giving me a run on a powershift Cat D9G (God, it was a BIG machine - then.) later in 1965, which stood me in good stead when I applied for the next job after that one, 'cos up till then, I had only run stick-shifts.

That old 980 with the V8 had the same 'donk' as the first 621 elevator scrapers, the J621's. I couldn't tell you the motor series but I'd be surprised if there isn't someone here who can. I ran one for a while in a quarry in Perth, Western Australia. I thought it worked well and gave very little trouble. It certainly had plenty of grunt and it did have its own unique exhaust note. I spent most of my time on it loading 2 x 30 ton Euclid dump trucks at the quarry face. I enjoyed it.

Like you, I also spent a bit of time on those old 46A's and really learned to know them and what they could do. I also spent a bit of time on 66A and 77V D9's and learned to appreciate them too. I've run a couple of 977's, K's and L's, and liked them too. I ran a couple of 988A's before I ran the 980A and a couple after it and I have to say I couldn't choose one over the other as far as operating was concerned. I didn't get to run it but I did work alongside a later 980 with the 3306 'donk' and it seemed to go well too.

Thanks for the memories.

[72V]

R.O.P., that would be the Cat D336 in that old 980, with dual overhead cams. The gear train on that thing must have been impressive. I'd like to hear that sound myself.

I have an old 1968 Kenworth truck with Cat 1767 series engine and was told it was the same as the early 621 scraper v8 engine.The truck has both the turbo and aftercooler,and is rated at 340 hp.Scrapers were just turbo charged.

I remember the early 621 scraper with the v8 they was nose heavy and always wanting to nose in the ground when coming down off a slope.Unlike the old 631,s with the fuel tank mounted on the back they was tail heavy and if not careful could stand it right up on the tank in the rear.

Looking staright up or down was always not that fun:eek: :usa

[GaryKelley]

Yea, I got one, turns out it was underpowered, so I sent it back and got a 4, in my opinion, they are the ONLY tracked machine with the right power-weight ratio...

[royce]

You are correct, it is the Cat D336 V8 engine, as a truck engine it was called the 1676. It was used in the earlier 980's and the early 621's . It seems it was Caterpillar's first attempt at a high performance engine, it featured dual overhead cams and a very compact block. Most models were rated around 300 horsepower, but I saw a yacht with 2 D336 marine engines, each rated at 420 horsepower. Their ones that I heard did have a very high pitched scream at wot.

It is 1676,like posted above, i believe.I was close ,just turned around some.The fuel injection pumps set to the rear of the v8 engine between the heads, and the aftercooler is on the outside of the fuel pump still between the heads,but higher.

[Deas Plant]

Hi, RollOverPete.
I've seen that page at Vanatta and I suspect that the machine in question is a D11, not a D10 - see twin exhaust stacks. Only the early D10's had twin stacks and that AIN'T an early one.

I don't know how true it is but I was told that it happened at a mine near Kalgoorlie in Western Australia. I was also told that it was driven out of there under its own 'steam' but I find that hard to believe. I suspect that the engine sensor system would not allow it to run in that position due to lack of oil for the pumps to pick up. Especially, I doubt that you would be able to re-start the engine once it had been shut down. I also suspect that if you tried to 'lift' the blade so that you could drive it on down the slope, you would be more likely to bring the rear of the machine right over the top of yourself. Now that would make life interesting for a moment or two.

[hvy 1ton]

If i remember correctly they lifted it up and set it on the pile then drove it down the pile. That might be what have been construed into "driving under its own steam. I forgot how they lifted it, but i think they pulled it up with a couple dozers.

The story I read....somewhere....
was that they secured the dozer from the top with some cables/blocks,other dozer's.
Then they ran a cable from the bottom and attached it to the dozer's blade.
Now they could pull or raise up on the blade so they wouldn't dig in and then lower the whole thing down from the top.
After that, it was just a matter of checking and adding fluids, pounding the huge "pinch" mark out of the drivers seat and I'm willing to bet a fresh change of underwear.:oops

I was under the impression that the D11T was going to be postponed...the first-run literature that I picked up still says the D11T retains the 3508B engine, though, again, I'm not sure if this to change.


Last I read, the D11T will have a C32 engine(around 32 liter displacement). A V-12 engine.
