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 in the parts catalogue. Experience has proven that this strategy is not as straight forward was many, including myself, would prefer it to be.
In the first place, lets begin with Truck Manual water pumps. Using a 4045 John Deere engine for example, perusing the various components 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 amount of water pumps available will increase. Occasionally, the application form (e.g Ag,or Construction) will help in zoning in to the correct pump. However, in almost most cases, the combinations of pumps would require further information. In this instance, the number that is certainly casted on the old water pump is necessary. This is regarded as a “Casting Number.” On the housing from the pump, a number will likely 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 produced in Dubuque, with no turbocharger, will have a water pump part quantity of RE21177. The part number of the housing is AR80109. John Deere will list both of these numbers as possessing a casting quantity of R59049.
The turbocharged John Deere Technical Manual could have a water pump part variety 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 new water pump, or perhaps a water pump overhaul kit.
This casting number phenomenon will not be limited to water pumps only. When ordering an engine overhaul kit, the piston number, as well as the connecting rod casting numbers are sometimes needed to identify which components are compatible.
Marine engines, as compared to construction engines, could have slightly varying components. An engine block for your marine engine for your 4045 engine could be slightly distinct from the engine block to get a 4045 tractor engine. Both are created for different applications, and may differ. Marine engines are engineered for continuous operations.
To respond to the question whether an engine block through the marine may be interchanged for the engine block coming from a generator, as an example, 2 things should be done.
One, compare the casting numbers for both blocks. This really is embossed on the side in the cylinder block. In the event the two numbers are identical, then this interchangeability is possible.
Two, compare the SAE housings of the two engines. It’s no use switching engine blocks around, to discover at late 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 details are invaluable in identifying correct parts and part numbers. An easy as it can certainly sound; the exact type of the machine is necessary. A 310 euyzoy is not really the same as a 310G backhoe. The serial variety of the device can also be needed. A serial number includes the engine model, and the machine type. John Deere’s online system provides a free service whereby the serial quantity of the equipment is inputted, and JD’s data is provided.
