John Deere, like other engine manufacturers, uses its unique terminology and arrangements, to mark its products, and assign part numbers. Understanding this marking categorization and product is essential to part number identification, that is then utilized to select rebuild kits, components, and maintenance parts.
A normal engine serial number looks like TO4045T123456. To better appreciate this number, it will be put into several parts. The very first segment is the two initial letters “TO.” Those two initial letters indicates a pair of things:- one, which country could it have been stated in, and secondly, when it is Powertech or non-Powertech.
All John Deere engines stated in Dubuque, Iowa, USA, are preceded from the letters “TO,” all engines preceded by “CD” are produced in Saran, a factory perfectly located at the Loiret section of France, and many types of engines created in Torreon, Mexico, are preceded with the letters “PE.”
The following list of numbers inside the John Deere engine serial number are four (4) or (5) numbers and letters. In our example, this describes “4045T.” This is further sub-divided to the “4045” and also the “T”. The 4045 indicated that that is 4045 model. Your initial “4” points too its build with four (4) cylinders. The “T’ that’s comes after the engine model no . tells the engine includes a turbocharger attached onto it, and thus this is a turbocharged engine. This factor is important as turbocharged engines are designed differently from non-turbocharged engines. Most importantly, parts might not be interchanged between these two kinds of engines.
The last group of six (6) numbers will be the sequential quantity of the engines mainly because it is removed the assembly line. If the number is 123456, then this next serial quantity of another engine on a single assembly line will be 123457. This will continue until John Deere decides it is time to upgrade in order to build another model.
There are numerous 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), that is certainly it’s naturally aspirated, i.e., it isn’t really turbocharged. Thus, this serial number could have 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 could be accompanied by a “D”, a “T” or perhaps a “H.”
The problem of the way to distinguish which engines are PowerTech and which aren’t non-PowerTech often arises. This could be solved by further dissecting the John Deere serial number.
For your engines produced in Dubuque, Iowa, USA,(TO Engines) all engines having a sequence number a lot more than 700,000 are Powertech engines.
For your engines manufactured in Sarran, France,(CD engines) all engines with sequence serial number more than 500,000 are Powertech engines.
On the contrary, however, all John Deere engines made in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number began with 1000 (1000). Thus, all PE PowerTech engines have a sequence serial quantity of one thousand (1000) or more.
