John Deere, like other engine manufacturers, uses its terminology and arrangements, to mark its products, also to assign part numbers. Understanding this marking categorization and method is important to part number identification, which can be then utilized to select rebuild kits, components, and maintenance parts.
A normal engine serial number appears like TO4045T123456. To higher understand why number, it will likely be split into several parts. The very first segment could be the two initial letters “TO.” These initial letters indicates a pair of things:Body, which country was it produced in, and secondly, whether it is Powertech or non-Powertech.
All John Deere engines stated in Dubuque, Iowa, USA, are preceded by the letters “TO,” all engines preceded by “CD” are manufactured in Saran, a factory found in the Loiret section of France, and all sorts of engines created in Torreon, Mexico, are preceded through the letters “PE.”
The following list of numbers within 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 often further sub-divided into the “4045” along with the “T”. The 4045 established that this really is 4045 model. Your initial “4” points too its build with four (4) cylinders. The “T’ that’s comes after the engine model number tells that this engine carries a turbocharger attached into it, and therefore this is the turbocharged engine. This factor is important as turbocharged engines were created differently from non-turbocharged engines. Most importantly, parts will not be interchanged between those two forms of engines.
The final group of six (6) numbers is the sequential amount of the engines as it comes off the assembly line. If this number is 123456, then the next serial amount of the next engine about the same assembly line will likely be 123457. This will continue until John Deere decides its time to upgrade or to build another model.
There are lots of variations of the above serial number. The model 4045T could be marked 4045D. Here the “D” symbolizes the engine is often a diesel engine (some early John Deere’s were manufactured to function on gas), and that is it’s naturally aspirated, i.e., it is not turbocharged. Thus, this serial number may have been TO4045D123456 which would have been distinct from the TO4045T123456.
The 4045 in ghd 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 then a “D”, a “T” or possibly a “H.”
The issue of methods to spot which engines are PowerTech and that are not non-PowerTech often arises. This is often solved by further dissecting the John Deere serial number.
For your engines made in Dubuque, Iowa, USA,(TO Engines) all engines using a sequence number a lot more than 700,000 are Powertech engines.
To the engines manufactured in Sarran, France,(CD engines) all engines with sequence serial number over 500,000 are common Powertech engines.
On the contrary, however, all John Deere engines produced 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 variety of one thousand (1000) or over.
