John Deere Engine Serial Numbers Detailed

John Deere, like other engine manufacturers, uses its terminology and arrangements, to mark its products, and also to assign part numbers. Understanding this marking categorization and system is important to part number identification, that is then accustomed to select rebuild kits, components, and maintenance parts.

A normal engine serial number appears like TO4045T123456. To raised understand this number, it’ll be put into several parts. The first segment will be the two initial letters “TO.” These initial letters indicates two things:- one, which country maybe it was produced in, and secondly, if it’s Powertech or non-Powertech.

All John Deere engines stated in Dubuque, Iowa, USA, are preceded through the letters “TO,” all engines preceded by “CD” are made in Saran, a factory located in the Loiret area of France, and all engines stated in Torreon, Mexico, are preceded with the letters “PE.”

The following set of numbers inside the John Deere engine serial number are four (4) or (5) numbers and letters. Within our example, this identifies “4045T.” This is often further sub-divided into the “4045” and the “T”. The 4045 revealed that this can be 4045 model. The initial “4” suggests that its build with four (4) cylinders. The “T’ that’s comes after the engine model number tells that this engine carries a turbocharger attached onto it, and thus it is a turbocharged engine. This factor is significant as turbocharged engines are made differently from non-turbocharged engines. Most significantly, parts is probably not interchanged between both of these sorts of engines.

The final group of six (6) numbers is the sequential quantity of the engines as it is removed the assembly line. If the number is 123456, then your next serial number of the following engine about the same assembly line will probably be 123457. This will continue until John Deere decides its time to upgrade in order to build another model.

There are many variations of the above serial number. The model 4045T may be marked 4045D. Here the “D” symbolizes the engine is a diesel engine (some early John Deere’s were manufactured to use on gas), and that’s it’s naturally aspirated, i.e., it is not turbocharged. Thus, this serial number has been TO4045D123456 which would have been totally different from the TO4045T123456.

The 4045 in ghd 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 can be as well as a “D”, a “T” or even a “H.”

The issue of precisely how to recognize which engines are PowerTech and who are not non-PowerTech often arises. This is solved by further dissecting the John Deere serial number.

For that engines stated in Dubuque, Iowa, USA,(TO Engines) all engines using a sequence number over 700,000 are typical Powertech engines.

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

On the other hand, however, all John Deere engines stated in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number began with 1,000 (1000). Thus, all PE PowerTech engines will have a sequence serial number of 1000 (1000) or higher.
