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 crucial to part number identification, that is then accustomed to select rebuild kits, components, and maintenance parts.
An average engine serial number looks like TO4045T123456. To higher understand why number, it’s going to be split into several parts. The 1st segment could be the two initial letters “TO.” Both of these initial letters indicates a pair of things:- one, which country could it have been produced in, and secondly, when it is Powertech or non-Powertech.
All John Deere engines produced in Dubuque, Iowa, USA, are preceded with the letters “TO,” all engines preceded by “CD” are made in Saran, a factory located in the Loiret part of France, and engines manufactured in Torreon, Mexico, are preceded from the letters “PE.”
The next group of numbers from the John Deere engine serial number are four (4) or (5) letters and numbers. In your example, this describes “4045T.” This can be further sub-divided into the “4045” along with the “T”. The 4045 revealed that this is 4045 model. The initial “4” shows that its build with four (4) cylinders. The “T’ that’s uses the engine model number tells that this engine has a turbocharger attached about it, thereby this can be a turbocharged engine. This factor is crucial as turbocharged engines are created differently from non-turbocharged engines. Most importantly, parts may not be interchanged between those two kinds of engines.
The last pair of six (6) numbers may be the sequential quantity of the engines mainly because it is removed the assembly line. If this number is 123456, then a next serial variety of the next engine on a single assembly line will be 123457. This will continue until John Deere decides it is time to upgrade or build another model.
There are lots of variations of the above serial number. The model 4045T might be marked 4045D. Here the “D” symbolizes that this engine is often a diesel engine (some early John Deere’s were manufactured to function on gas), that is certainly it’s naturally aspirated, i.e., it isn’t turbocharged. Thus, this serial number has been TO4045D123456 and also this could have been totally 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 are often then a “D”, a “T” or possibly a “H.”
The problem of the way to distinguish which engines are PowerTech and who 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 common Powertech engines.
To the engines produced in Sarran, France,(CD engines) all engines with sequence serial number greater than 500,000 are all Powertech engines.
However, however, all John Deere engines manufactured in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number began with a thousand (1000). Thus, all PE PowerTech engines have a sequence serial amount of a thousand (1000) or more.
