John Deere Engine Serial Numbers Defined

John Deere, like other engine manufacturers, uses its terminology and arrangements, to mark its products, and assign part numbers. Understanding this marking categorization and strategy is crucial to part number identification, that’s then utilized to select rebuild kits, components, and maintenance parts.

A standard engine serial number looks like TO4045T123456. To higher understand this number, it’ll be split into several parts. The 1st segment may be the two initial letters “TO.” These two initial letters indicates a couple of things:- one, which country was it created in, and secondly, whether it is Powertech or non-Powertech.

All John Deere engines manufactured in Dubuque, Iowa, USA, are preceded from the letters “TO,” all engines preceded by “CD” are made in Saran, a factory found in the Loiret part of France, and all sorts of engines created in Torreon, Mexico, are preceded through the letters “PE.”

The next list of numbers from the John Deere engine serial number are four (4) or (5) numbers and letters. In our example, this is the term for “4045T.” This is often further sub-divided to the “4045” and also the “T”. The 4045 established that this can be 4045 model. The first “4” indicates that its build with four (4) cylinders. The “T’ that’s practices the engine model number tells that the engine has a turbocharger attached onto it, and therefore this is the turbocharged engine. This factor is significant as turbocharged engines were created differently from non-turbocharged engines. Most importantly, parts is probably not interchanged between these kinds of engines.

The final group of six (6) numbers is the sequential amount of the engines mainly because it comes off the assembly line. If the number is 123456, then a next serial number of another engine for a passing fancy assembly line will be 123457. This will likely continue until John Deere decides its time to upgrade or to build another model.

There are lots of variations of the above serial number. The model 4045T could be marked 4045D. Here the “D” symbolizes that the engine is often a diesel engine (some early John Deere’s were manufactured to work on gas), and that is it’s naturally aspirated, i.e., it isn’t turbocharged. Thus, this serial number has been TO4045D123456 this also could have been distinct from the TO4045T123456.

The 4045 in serial numbers can even be 3152, 3164, 3179, 3029, 4202, 4219, 4239, 4039, 4276, 6303, 6329, 6059, 6414, 6068, 6414, 4270, 6404, 6466, or 6076. They may be followed by a “D”, a “T” or a “H.”

The issue of the way to identify which engines are PowerTech and which are not non-PowerTech often arises. This can be solved by further dissecting the John Deere serial number.

For the engines manufactured in Dubuque, Iowa, USA,(TO Engines) all engines with a sequence number a lot more than 700,000 are all Powertech engines.

For your engines made in Sarran, France,(CD engines) all engines with sequence serial number over 500,000 are Powertech engines.

On the contrary, however, all John Deere engines stated in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number began with 1000 (1000). Thus, all PE PowerTech engines may sequence serial amount of 1,000 (1000) or more.
