John Deere Engine Parts For Vintage Tractor Restoration

John Deere, like other engine manufacturers, uses it is distinguishable terminology and arrangements, to mark it is products, and to assign percentage numbers. Understanding this marking categorization and scheme is primary to share number identification, which is then used to select rebuild kits, components, and maintenance parts.

A typical engine serial number looks like TO4045T123456. To better understand this number, it will be split into assorted parts. The introductory segment is the two firstborn letters “TO.” These two original letters gives evidence of two things:- one, which country was it fictitious in, and secondly, if it is Powertech or non-Powertech.

All John Deere engines fabricated in Dubuque, Iowa, USA, are preceded by the letters “TO,” all engines preceded by “CD” are fabricated in Saran, a factory located in the Loiret area of France, and all engines fictitious in Torreon, Mexico, are preceded by the letters “PE.”

The next set of numbers in the John Deere engine serial number are four (4) or (5) numbers and letters. In our example, this refers to “4045T.” This may be further sub-divided into the “4045″ and the “T”. The 4045 indicated that this is 4045 model. The firstborn “4″ gives evidence of that it is build with four (4) cylinders. The “T’ that’s comes after the engine model number tells that the engine has a turbocharger attached onto it, and therefore this is a turbocharged engine. This element is significant as turbocharged engines are designed differently from non-turbocharged engines. Most importantly, parts may not be counterchanged amidst these two kinds of engines.

The last set of six (6) numbers is the sequential number of the engines as it comes off the assemblage line. If this number is 123456, then the next serial number of the next engine on the same assemblage line will be 123457. This will proceed until John Deere decides it is time to upgrade or to build another model.

There are a heap of variations of the above serial number. The model 4045T may be marked 4045D. Here the “D” symbolizes that the engine is a diesel engine (some early John Deere’s were fabricated to operate on gas), and that’s it’s naturally aspirated, i.e., it’s not turbocharged. Thus, this serial number could have been TO4045D123456 and this would have been altogether dissimilar from the TO4045T123456.

The 4045 in serial numbers may likewise 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 a “H.”

The issue of how to tell apart which engines are PowerTech and which are not non-PowerTech oftentimes arises. This may be solved by further dissecting the John Deere serial number.

For the engines made in Dubuque, Iowa, USA,(TO Engines) all engines with a sequence number more than 700,000 are all Powertech engines.

For the engines made in Sarran, France,(CD engines) all engines with sequence serial number more than 500,000 are all Powertech engines.

On the contrary, however,, all John Deere engines made in Torreon, Mexico, (PE engines) are PowerTech engines. This sequence serial number begun with one thousand (1000). Thus, all PE PowerTech engines will have a sequence serial number of one thousand (1000) and up.
