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 in the parts catalogue. Experience has proven that this strategy is not as easy was many, including myself, would prefer it to be.
To begin with, lets get started with Truck Manual water pumps. Using a 4045 John Deere engine for instance, perusing the various components manuals would reveal many different water pumps that may fit a 4045 engine. Considering that we now have 4045, 4045D, and 4045T engines, the number of water pumps available improves. In some instances, the application (e.g Ag,or Construction) will help in zoning in to the correct pump. However, in almost many instances, 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 of the pump, a number is going to 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, with no turbocharger, may have a water pump part variety of RE21177. The part number of the housing is AR80109. John Deere will list both these numbers as possessing a casting quantity of R59049.
The turbocharged John Deere Service Manual will 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 brand new water pump, or even a water pump overhaul kit.
This casting number phenomenon is not confined to water pumps only. When ordering an engine overhaul kit, the piston number, as well as the connecting rod casting numbers are occasionally necessary to identify which components are compatible.
Marine engines, as compared to construction engines, will have slightly varying components. An engine block for the marine engine for that 4045 engine may be slightly distinctive from the engine block to get a 4045 tractor engine. Both are created for different applications, and can be different. Marine engines are specially designed for continuous operations.
To answer the question whether an engine block from your marine may be interchanged for an engine block from the generator, for instance, two things must be done.
One, compare the casting numbers on blocks. This really is embossed on the side from the cylinder block. If the two numbers are identical, then the interchangeability can be done.
Two, compare the SAE housings of these two engines. It’s no use switching engine blocks around, to learn at late that the SAE housings will vary, and thus, the transmission should not be bolted on.
While writing on the issue of Takeuchi Tl140 Workshop Manual casting numbers, other relatively simple information is invaluable in identifying correct parts and part numbers. A basic as it may sound; the precise style of the machine is required. A 310 euyzoy is not really exactly like a 310G backhoe. The serial quantity of the machine is additionally needed. A serial number will include the engine model, and also the machine type. John Deere’s online system offers a free service whereby the serial variety of the device is inputted, and JD’s data is provided.
