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 technique is not as easy was many, including myself, would prefer it to be.
To start with, lets get started with Truck Repair Manual water pumps. Employing a 4045 John Deere engine for example, perusing the parts manuals would reveal a variety of water pumps which could fit a 4045 engine. Considering there are 4045, 4045D, and 4045T engines, the amount of water pumps available improves. In some instances, the application form (e.g Ag,or Construction) can assist in zoning in to the correct pump. However, in almost many cases, the combinations of pumps would require additional information. In cases like this, 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 starts 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, 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 using a casting number of R59049.
The turbocharged John Deere Service 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 in your aftermarket parts dealers when requesting a whole new water pump, or a water pump overhaul kit.
This casting number phenomenon will not be restricted to water pumps only. When ordering an engine overhaul kit, the piston number, and the connecting rod casting numbers are occasionally required to identify which components are compatible.
Marine engines, in comparison with construction engines, could have slightly varying components. An engine block for that marine engine for the 4045 engine can be slightly distinctive from the engine block for a 4045 tractor engine. Both of them are created for different applications, and can differ. Marine engines were created for continuous operations.
To reply to the question as to whether an engine block from the marine can be interchanged for the engine block from the generator, for instance, a couple of things has to be done.
One, compare the casting numbers for both blocks. This is embossed on the side from the cylinder block. If the two numbers are identical, then your interchangeability can be done.
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 for that reason, the transmission cannot 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. A basic as it might sound; the exact style of the machine is needed. A 310 euyzoy is not the same as a 310G backhoe. The serial quantity of the equipment is also needed. A serial number will incorporate the engine model, and the machine type. John Deere’s online system delivers a free service whereby the serial number of the equipment is inputted, and JD’s information is provided.
