John Deere, like other engine manufacturers, uses its terminology and arrangements, to mark its products, and assign part numbers. Understanding this marking categorization and strategy is important to part number identification, which is then accustomed to select rebuild kits, components, and maintenance parts.
A typical engine serial number looks like TO4045T123456. To higher appreciate this number, it will likely be split into several parts. The first segment could be the two initial letters “TO.” These two initial letters indicates a couple of things:Body, which country could it have been manufactured in, and secondly, if 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 designed in Saran, a factory found in the Loiret division of France, and engines produced in Torreon, Mexico, are preceded through the letters “PE.”
The subsequent list of numbers in the John Deere engine serial number are four (4) or (5) letters and numbers. In our example, this refers to “4045T.” This is further sub-divided in the “4045” and the “T”. The 4045 indicated that this really is 4045 model. Your initial “4” indicates that its build with four (4) cylinders. The “T’ that’s uses the engine model no . tells how the engine features a turbocharger attached in it, and so this can be a turbocharged engine. This factor is critical as turbocharged engines were created differently from non-turbocharged engines. Most of all, parts may not be interchanged between these types of engines.
The very last set of six (6) numbers could be the sequential number of the engines mainly because it comes off the assembly line. If the number is 123456, then the next serial variety of the subsequent engine for a passing fancy assembly line will probably be 123457. This may continue until John Deere decides its a pointer to upgrade or to build another model.
There are many variations of the aforementioned serial number. The model 4045T may be marked 4045D. Here the “D” symbolizes that this engine is 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 really turbocharged. Thus, this serial number has been TO4045D123456 this also would’ve been totally 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 followed by a “D”, a “T” or even a “H.”
The issue of how to identify 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 that engines produced in Dubuque, Iowa, USA,(TO Engines) all engines which has a sequence number greater than 700,000 are typical Powertech engines.
For the engines manufactured in Sarran, France,(CD engines) all engines with sequence serial number greater than 500,000 are all Powertech engines.
On the other hand, 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 may sequence serial number of 1,000 (1000) and up.
