Can somebody tell me what the numbers mean for eg. 3408. I would think the no. 8 would indicate how many cylinders. thanks Deano

That is correct. In this engine numbering system, the last two digits are the number of cylinders. The second digit indicates the cylinder size family. Common varriants of the family are the 3406, 3408 and 3412. You may also find a letter after the engine, which indicates a generation family of the engine. These include the un-numbered A and then the Cat numbered B, C and E series. The C family began the emissions systems and the E added electronic engine management.

In 3408 the 3 designates an engine, the 4 designates the engine family by the cylinder displacement (bore and stroke). I can’t remember what the 3rd digit is but it does stand for something. But when you get into 12 cylinder and larger engines the 3rd digit is the first digit for the number of cylinders. The 4th digit is number of engine cylinders. In the older Caterpillar performance handbooks they have a breakdown of the engine numbering code but I don’t have one in front of me at the moment. Then after the 3408 you may have additional letters like T for turbo and TA for turbo charged and after cooled. There are a handful of other letter combinations as well that I cannot think of off the top of my head.

The families are 3100, 3200, 3300, 3400, 3500 & 3600, the last 2 digits represent the number of cylinders ie 3208 = 8 cylinder engine, 3412 = 12 cylinder engine and so on.
There is another series of Cat engines starting with D and in the 300 family ie D342, D348, D353, D379, the last 2 digits in this family have no reference to cylinder numbers and are just in a sequence with no real meaning.

The exceptions to Gavin's statement are the 3116, 3126 and 3176 engines which are all six cylinder engines. The 3116 and 3126 are so closely related that I could argue that the third digit is a generation number. That is not true of the 3176.
The smaller 3000 series engines were succeeded by the "C" series which was the final truck engine generation and continues in the equipment.
They were preceeded by the "D" series in equipment and "1600" series in trucks. I cannot remember the 3208's precedecessor, but the 1673 and 1693 were some of the first Cat class 8 truck engines.

The "D" was not a series but implied that it was a Diesel version of the engine compared to a "G" version which implied Gaseous fueled. When they went to the 3### numbering they dropped the “D” but kept the G to designate gaseous fueled engines since you could get almost any engine in a gaseous fuel version, such as the G3408.

. In addition to the above there is also the 3000 family of engines. DC Craneman wrote:The exceptions to Gavin's statement are the 3116, 3126 and 3176 engines which are all six cylinder engines.

There are many more exceptions concerning the 3rd digit. These would be the 3114 and 3054 (both 4 cylinders) along with the 3216, 3196, 3013, 3456 and many others. The 3196 is the industrial version of the C-12 and the 3456 is a continuation of the 3406 which was available in two displacements (14.6L) and the enlarged version (15.8L). In the current engine line up there is also the V and VM line of engines that are built by MaK plus the turbines which are a whole other animal with the families having names like Titan, Mars, Taurus, Saturn, Mercury and Centaur.

What models are there in the 3000 series? Do you mean the 3456?

1145 & 1160 i think it was, there was also the V636 specifically built for Ford in the Louisville line of trucks. Bet y'all did not know Cat built 3 3206 experimental V6 engines with 1 surviving in a Peoria museum.

The 3000 series is what you would find in little skid steers and mini excavators. The 3054 was in backhoes and right around 100hp or so. Other 3000 series engines would be the 3056, 3054, 3044, 3034, 3024, 3014, 3013, 3011 and the 3003. They are mostly if not all the Perkins built Cats.

Is this the same 3206 that Cat looked at building for Chevy when they were looking for a new engine 14 years ago or so? They looked at Cat and John Deere.

No, this one was being developed many years prior to 14 ago, more around the same time as the 3208 it self or a short time after.

Did Cat not buy out Perkins? maybe as a shrude move to give JCB a headache,as JCB used Perkins in their 3cx's?
Why is "phonetically" spelt with a "ph"? ... It's better to be silent and thought a fool, then to speak up and remove all doubt The complex of Newgrange was originally built between c. 3100 and 2900 BC,[2] meaning that it's aproximately 5,000 years old. According to Carbon-14 dates,[3] it is more than 500 years older than the Great Pyramid of Giza in Egypt, and predates Stonehenge by about 1,000 years.

Yes, I believe that Perkins is owned by Cat. Please don't hold me to this, but it may well be the sources for the 3000 series or 30XX series.
When looking at the Cat engine family, we cannot forget that they now own Electromotive which gives them another family of production engines as well as designs and parts for several others.
Likewise, the forthcoming 15 litre Maxforce engine from International is another evolution of the C15 from the 3406. We shall have to wait and see where the differences are. The changes during the 1990s and 2000s were evolutionary and emissions driven in the 6 to 15 litre sizes of the Cat line.
