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 system is important to part number identification, that’s then utilized to select rebuild kits, components, and maintenance parts.
A standard engine serial number looks like TO4045T123456. To better see why number, it will likely be split into several parts. The initial segment may be the two initial letters “TO.” These initial letters indicates a pair of things:- one, which country maybe it was created in, and secondly, whether it is Powertech or non-Powertech.
All John Deere engines created in Dubuque, Iowa, USA, are preceded by the letters “TO,” all engines preceded by “CD” are produced in Saran, a factory perfectly located at the Loiret section of France, and engines stated in Torreon, Mexico, are preceded with the letters “PE.”
The subsequent group of numbers within the John Deere engine serial number are four (4) or (5) letters and numbers. In your example, this refers to “4045T.” This is further sub-divided to the “4045” and the “T”. The 4045 established that this is 4045 model. The original “4” points too its build with four (4) cylinders. The “T’ that’s practices the engine model no . tells that this engine includes a turbocharger attached about it, and therefore this is the turbocharged engine. This factor is crucial as turbocharged engines were created differently from non-turbocharged engines. Above all, parts may not be interchanged between these two sorts of engines.
The final pair of six (6) numbers is the sequential quantity of the engines since it comes off the assembly line. If it number is 123456, then this next serial variety of another engine for a passing fancy assembly line will probably be 123457. This can continue until John Deere decides it is time to upgrade or build another model.
There are several variations of the above serial number. The model 4045T could be marked 4045D. Here the “D” symbolizes that the engine is really a diesel engine (some early John Deere’s were manufactured to function on gas), and that is it’s naturally aspirated, i.e., it isn’t really turbocharged. Thus, this serial number has been TO4045D123456 and also this would have been completely different from the TO4045T123456.
The 4045 in 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 are often accompanied by a “D”, a “T” or even a “H.”
The problem of methods to distinguish 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 having a sequence number more than 700,000 are typical Powertech engines.
For that engines made in Sarran, France,(CD engines) all engines with sequence serial number over 500,000 are Powertech engines.
On the other hand, however, all John Deere engines made in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number began with a thousand (1000). Thus, all PE PowerTech engines will have a sequence serial number of one thousand (1000) and up.
