John Deere, like other engine manufacturers, uses its unique terminology and arrangements, to mark its products, also to assign part numbers. Understanding this marking categorization and method is imperative to part number identification, which can be then accustomed to select rebuild kits, components, and maintenance parts.
A standard engine serial number appears like TO4045T123456. To better understand this number, it’s going to be put into several parts. The first segment may be the two initial letters “TO.” Both of these initial letters indicates a couple of things:Body, which country could it have been created in, and secondly, if it’s Powertech or non-Powertech.
All John Deere engines stated in Dubuque, Iowa, USA, are preceded with the letters “TO,” all engines preceded by “CD” are designed in Saran, a factory perfectly located at the Loiret area of France, and all sorts of engines created in Torreon, Mexico, are preceded by the letters “PE.”
The next set 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 further sub-divided into the “4045” and also the “T”. The 4045 indicated that this can be 4045 model. Your initial “4” suggests that its build with four (4) cylinders. The “T’ that’s comes after the engine model number tells that this engine has a turbocharger attached into it, and so this is the turbocharged engine. This factor is significant as turbocharged engines are made differently from non-turbocharged engines. Most significantly, parts may not be interchanged between these two sorts of engines.
The past pair of six (6) numbers may be the sequential amount of the engines since it comes off the assembly line. If the number is 123456, then a next serial number of another engine about the same assembly line will probably be 123457. This may continue until John Deere decides it is time to upgrade or to build another model.
There are several variations of the aforementioned serial number. The model 4045T could 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), that is certainly it’s naturally aspirated, i.e., it is not turbocharged. Thus, this serial number may have been TO4045D123456 and also this would’ve been completely different from the TO4045T123456.
The 4045 in serial numbers can also 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 possibly a “H.”
The situation of the way to spot which engines are PowerTech and which are not non-PowerTech often arises. This could be solved by further dissecting the John Deere serial number.
To the engines made in Dubuque, Iowa, USA,(TO Engines) all engines which has a sequence number a lot more than 700,000 are all Powertech engines.
For that engines manufactured in Sarran, France,(CD engines) all engines with sequence serial number a lot more than 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 one thousand (1000). Thus, all PE PowerTech engines may sequence serial quantity of 1,000 (1000) or more.
