The identification of John Deere Parts occasionally, are not as easy as providing a serial number of a machine, or a serial number of an engine, and then the parts are looked up in the parts catalogue. Experience has proven that this method is not as straight forward was many, including myself, would prefer it to be.
To begin with, lets begin with Truck Manual water pumps. Utilizing a 4045 John Deere engine as an example, perusing the parts manuals would reveal a variety of water pumps which could fit a 4045 engine. Taking into account there are 4045, 4045D, and 4045T engines, the amount of water pumps available will increase. In some instances, the applying (e.g Ag,or Construction) will help in zoning in to the correct pump. However, in almost many cases, the mixtures of pumps would require additional information. In this case, the number which is casted on the old water pump is necessary. This is actually a “Casting Number.” On the housing of the pump, a number will be embossed.
Typically, this starts off with the letter “R” or “T.” Thus, both T29701 and R55971 are John Deere water pump casting numbers.
The 4045 John Deere engines made in Dubuque, with no turbocharger, will have a water pump part number of RE21177. The part number of the housing is AR80109. John Deere will list both of these numbers as possessing a casting variety of R59049.
The turbocharged John Deere Manual PDF may have a water pump part number of AR77142. The housing part number is AR80116. This engine water pump has two different casting numbers, R90784, and R104648. Provide these numbers to your aftermarket parts dealers when requesting a brand new water pump, or even a water pump overhaul kit.
This casting number phenomenon is not really confined to water pumps only. When ordering an engine overhaul kit, the piston number, and the connecting rod casting numbers are often required to identify which components are compatible.
Marine engines, when compared with construction engines, may have slightly varying components. An engine block for that marine engine for the 4045 engine could be slightly different from the engine block for any 4045 tractor engine. Both are made for different applications, and may be different. Marine engines are specially designed for continuous operations.
To respond to the question whether an engine block from your marine may be interchanged to have an engine block from the generator, for example, a couple of things should be done.
One, compare the casting numbers for both blocks. This really is embossed on the side from the cylinder block. In the event the two numbers are identical, then the interchangeability is possible.
Two, compare the SAE housings of these two engines. It’s no use switching engine blocks around, to discover at late that the SAE housings will vary, and therefore, the transmission should not be bolted on.
While writing on the issue of Takeuchi Tl140 Service Manual casting numbers, other relatively simple information and facts are invaluable in identifying correct parts and part numbers. An easy as it may sound; the exact style of the machine is needed. A 310 euyzoy is not exactly like a 310G backhoe. The serial quantity of the equipment is additionally needed. A serial number will incorporate the engine model, as well as the machine type. John Deere’s online system provides a free service whereby the serial quantity of the device is inputted, and JD’s data is provided.
