John Deere, like other engine manufacturers, uses its unique terminology and arrangements, to mark its products, and also to assign part numbers. Understanding this marking categorization and strategy is crucial to part number identification, that is then employed to select rebuild kits, components, and maintenance parts.
A normal engine serial number appears to be TO4045T123456. To better understand why number, it’s going to be separated into several parts. The very first segment will be the two initial letters “TO.” Those two initial letters indicates certain things:Body, which country maybe it was manufactured in, and secondly, if it’s Powertech or non-Powertech.
All John Deere engines manufactured in Dubuque, Iowa, USA, are preceded through the letters “TO,” all engines preceded by “CD” are produced in Saran, a factory perfectly located at the Loiret division of France, and all sorts of engines manufactured in Torreon, Mexico, are preceded from the letters “PE.”
Another pair of numbers within the John Deere engine serial number are four (4) or (5) numbers and letters. Inside our example, this is the term for “4045T.” This is often further sub-divided into the “4045” along with the “T”. The 4045 indicated that this is 4045 model. The first “4” suggests that its build with four (4) cylinders. The “T’ that’s uses the engine model no . tells how the engine has a turbocharger attached into it, and therefore it is a turbocharged engine. This factor is important as turbocharged engines are made differently from non-turbocharged engines. Most of all, parts may not be interchanged between those two sorts of engines.
The final group of six (6) numbers will be the sequential variety of the engines because it is removed the assembly line. If the number is 123456, then this next serial quantity of the next engine on a single assembly line will probably be 123457. This may continue until John Deere decides its time to upgrade or build another model.
There are lots of variations of the above serial number. The model 4045T can be marked 4045D. Here the “D” symbolizes that this engine is often a diesel engine (some early John Deere’s were manufactured to use on gas), that is certainly it’s naturally aspirated, i.e., it’s not turbocharged. Thus, this serial number may have been TO4045D123456 which would have been totally different from the TO4045T123456.
The 4045 in ghd serial numbers may also be 3152, 3164, 3179, 3029, 4202, 4219, 4239, 4039, 4276, 6303, 6329, 6059, 6414, 6068, 6414, 4270, 6404, 6466, or 6076. They may be accompanied by a “D”, a “T” or possibly a “H.”
The issue of precisely how to spot which engines are PowerTech and which are not non-PowerTech often arises. This could be solved by further dissecting the John Deere serial number.
For that engines produced in Dubuque, Iowa, USA,(TO Engines) all engines using a sequence number over 700,000 are Powertech engines.
To the engines made 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 made in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number began with 1,000 (1000). Thus, all PE PowerTech engines will have a sequence serial amount of one thousand (1000) or higher.
