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 essential to part number identification, that’s then accustomed to select rebuild kits, components, and maintenance parts.
A normal engine serial number looks like TO4045T123456. To improve understand why number, it’ll be put into several parts. The very first segment may be the two initial letters “TO.” Both of these initial letters indicates a couple of things:Body, which country is it manufactured in, and secondly, whether it is Powertech or non-Powertech.
All John Deere engines stated in Dubuque, Iowa, USA, are preceded through the letters “TO,” all engines preceded by “CD” are manufactured in Saran, a factory found in the Loiret area of France, and many types of engines produced in Torreon, Mexico, are preceded with the letters “PE.”
The subsequent pair of numbers within the John Deere engine serial number are four (4) or (5) numbers and letters. Within our example, this describes “4045T.” This is further sub-divided into the “4045” and also the “T”. The 4045 revealed that this really is 4045 model. The original “4” indicates that its build with four (4) cylinders. The “T’ that’s employs the engine model number tells how the engine features a turbocharger attached about it, thereby it is a turbocharged engine. This factor is crucial as turbocharged engines are created differently from non-turbocharged engines. Above all, parts might not be interchanged between those two kinds of engines.
The final set of six (6) numbers will be the sequential variety of the engines as it comes off the assembly line. If the number is 123456, then a next serial variety of another engine for a passing fancy assembly line will likely be 123457. This can continue until John Deere decides its time to upgrade or to build another model.
There are several variations of the aforementioned serial number. The model 4045T can be marked 4045D. Here the “D” symbolizes that the engine is a diesel engine (some early John Deere’s were manufactured to operate on gas), which is it’s naturally aspirated, i.e., it isn’t turbocharged. Thus, this serial number could have been TO4045D123456 which could have been distinct 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 accompanied by a “D”, a “T” or even a “H.”
The matter of how to identify which engines are PowerTech and which are not non-PowerTech often arises. This can be solved by further dissecting the John Deere serial number.
To the engines stated in Dubuque, Iowa, USA,(TO Engines) all engines having a sequence number over 700,000 are Powertech engines.
To the engines stated in Sarran, France,(CD engines) all engines with sequence serial number more than 500,000 are 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 1000 (1000). Thus, all PE PowerTech engines will have a sequence serial variety of 1000 (1000) or higher.
