The identification of John Deere Parts occasionally, are not as simple 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 method is not as simple was many, including myself, would prefer it to be.
To start with, lets begin with Truck Manual water pumps. Utilizing a 4045 John Deere engine as an example, perusing the parts manuals would reveal many different water pumps that may fit a 4045 engine. Taking into account that we now have 4045, 4045D, and 4045T engines, the quantity of water pumps available increases. In some instances, the application form (e.g Ag,or Construction) will assist in zoning in to the correct pump. However, in almost many cases, the mixtures of pumps would require further information. In this case, the number which is casted on the old water pump is needed. This is known as a “Casting Number.” On the housing from the pump, a number will be embossed.
Typically, this begins 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, without any turbocharger, will have a water pump part number of RE21177. The part number of the housing is AR80109. John Deere will list these two numbers as possessing a casting quantity of R59049.
The turbocharged John Deere Manual PDF could 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 for your aftermarket parts dealers when requesting a whole new water pump, or a water pump overhaul kit.
This casting number phenomenon will not be confined to water pumps only. When ordering an engine overhaul kit, the piston number, as well as the connecting rod casting numbers are often needed to identify which components are compatible.
Marine engines, when compared with construction engines, will have slightly varying components. An engine block for your marine engine for your 4045 engine can be slightly distinctive from the engine block for any 4045 tractor engine. Both of them are created for different applications, and will be different. Marine engines are engineered for continuous operations.
To reply to the question as to whether an engine block from your marine may be interchanged to have an engine block from the generator, for instance, two things has to be done.
One, compare the casting numbers on both blocks. This really is embossed on the side from the cylinder block. If the two numbers are identical, then this interchangeability can be done.
Two, compare the SAE housings of these two engines. It’s no use switching engine blocks around, to find out at late that this SAE housings are different, and thus, the transmission can 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. A simple as it may sound; the actual style of the device is needed. A 310 euyzoy will not be exactly like a 310G backhoe. The serial number of the device is additionally needed. A serial number includes the engine model, and the machine type. John Deere’s online system offers a free service whereby the serial variety of the equipment is inputted, and JD’s information is provided.
