The identification of John Deere Parts at times, 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 within the parts catalogue. Experience has proven that this technique is not as easy was many, including myself, would prefer it to be.
To start with, lets start with Truck Repair Manual water pumps. Utilizing a 4045 John Deere engine for example, perusing the parts manuals would reveal many different water pumps that could fit a 4045 engine. Considering that we now have 4045, 4045D, and 4045T engines, the number of water pumps available improves. Occasionally, the application (e.g Ag,or Construction) will help in zoning into the correct pump. However, in almost most cases, the combinations of pumps would require more information. In this instance, the amount which is casted on the old water pump is required. This is actually a “Casting Number.” On the housing of the pump, a number is going to be embossed.
Typically, this starts with the letter “R” or “T.” Thus, both T29701 and R55971 are John Deere water pump casting numbers.
The 4045 John Deere engines produced in Dubuque, without any turbocharger, may have a water pump part variety of RE21177. The part quantity of the housing is AR80109. John Deere will list both of these numbers as possessing a casting variety of R59049.
The turbocharged John Deere Technical Manual could have a water pump part quantity 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 a water pump overhaul kit.
This casting number phenomenon is not limited to water pumps only. When ordering an engine overhaul kit, the piston number, and also the connecting rod casting numbers are often necessary to identify which components are compatible.
Marine engines, when compared with construction engines, will have slightly varying components. An engine block for that marine engine for that 4045 engine could be slightly distinctive from the engine block for any 4045 tractor engine. They are both made for different applications, and can be different. Marine engines are engineered for continuous operations.
To reply to the question whether an engine block from the marine could be interchanged for an engine block coming from a generator, for instance, two things has to be done.
One, compare the casting numbers on both blocks. This can be embossed on the side in the cylinder block. In the event the two numbers are identical, then this interchangeability can be done.
Two, compare the SAE housings of the two engines. It’s no use switching engine blocks around, to learn at late that this SAE housings will vary, and therefore, the transmission can not be bolted on.
While writing on the issue of Takeuchi Tl140 Workshop Manual casting numbers, other relatively simple information and facts are invaluable in identifying correct parts and part numbers. A simple as it may sound; the actual type of the machine is required. A 310 euyzoy will not be the same as a 310G backhoe. The serial number of the device can also be needed. A serial number includes the engine model, and also the machine type. John Deere’s online system delivers a free service whereby the serial number of the machine is inputted, and JD’s data is provided.
