John Deere, like other engine manufacturers, uses its terminology and arrangements, to mark its products, and to assign part numbers. Understanding this marking categorization and strategy is essential to part number identification, which is then utilized to select rebuild kits, components, and maintenance parts.
An average engine serial number seems like TO4045T123456. To improve understand this number, it will be separated into several parts. The 1st segment may be the two initial letters “TO.” Both of these initial letters indicates two things:Body, which country was it created in, and secondly, when it is Powertech or non-Powertech.
All John Deere engines created in Dubuque, Iowa, USA, are preceded from the letters “TO,” all engines preceded by “CD” are produced in Saran, a factory found in the Loiret part of France, and engines produced in Torreon, Mexico, are preceded through the letters “PE.”
The next group of numbers in the John Deere engine serial number are four (4) or (5) numbers and letters. Within our example, this refers to “4045T.” This could be further sub-divided to the “4045” and the “T”. The 4045 indicated that this can be 4045 model. The original “4” points too its build with four (4) cylinders. The “T’ that’s uses the engine model no . tells that the engine carries a turbocharger attached into it, and thus this is the turbocharged engine. This factor is important as turbocharged engines are made differently from non-turbocharged engines. Most importantly, parts will not be interchanged between these two forms of engines.
The last list of six (6) numbers may be the sequential number of the engines mainly because it comes off the assembly line. If the number is 123456, then a next serial amount of the following engine on the same assembly line will probably be 123457. This will continue until John Deere decides its time to upgrade or to build another model.
There are numerous variations of the aforementioned serial number. The model 4045T can be marked 4045D. Here the “D” symbolizes that this engine is often a diesel engine (some early John Deere’s were manufactured to work on gas), which is it’s naturally aspirated, i.e., it isn’t really turbocharged. Thus, this serial number may have been TO4045D123456 and this would have been completely 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 may be as well as a “D”, a “T” or possibly a “H.”
The situation of methods 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.
To the engines stated in Dubuque, Iowa, USA,(TO Engines) all engines using a sequence number a lot more than 700,000 are all Powertech engines.
To the engines stated in Sarran, France,(CD engines) all engines with sequence serial number over 500,000 are typical Powertech engines.
On the contrary, however, all John Deere engines manufactured in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number began with 1,000 (1000). Thus, all PE PowerTech engines have a sequence serial amount of one thousand (1000) and up.
