The identification of John Deere Parts sometimes, 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 technique is not as easy was many, including myself, would prefer it to be.
To start with, lets start with Truck Manual water pumps. Employing a 4045 John Deere engine as an example, perusing the various components manuals would reveal a variety of water pumps that could fit a 4045 engine. Considering that we now have 4045, 4045D, and 4045T engines, the quantity of water pumps available improves. In some circumstances, the applying (e.g Ag,or Construction) will assist in zoning into the correct pump. However, in almost most cases, the mixtures of pumps would require more information. In cases like this, the number that is certainly casted on the old water pump is required. This is regarded as a “Casting Number.” On the housing in 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 produced in Dubuque, without any turbocharger, could have a water pump part number of RE21177. The part number of the housing is AR80109. John Deere will list these two numbers as having a casting variety of R59049.
The turbocharged John Deere Service Manual 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 to your aftermarket parts dealers when requesting a new water pump, or perhaps 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 needed to identify which components are compatible.
Marine engines, in comparison with construction engines, may have slightly varying components. An engine block for that marine engine for your 4045 engine may be slightly distinctive from the engine block to get a 4045 tractor engine. Both of them are created for different applications, and can differ. Marine engines are specially designed for continuous operations.
To respond to the question as to whether an engine block from your marine can be interchanged for an engine block coming from a generator, for instance, a couple of things should be done.
One, compare the casting numbers on both blocks. This really is embossed on the side in the cylinder block. If the two numbers are identical, then the 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 are not the same, and therefore, the transmission can not be bolted on.
While writing on the issue of Takeuchi Tl140 Service Manual casting numbers, other relatively simple information is invaluable in identifying correct parts and part numbers. A basic as it can certainly sound; the precise type of the device is required. A 310 euyzoy will not be just like a 310G backhoe. The serial variety of the machine is also needed. A serial number includes the engine model, and the machine type. John Deere’s online system provides a free service whereby the serial number of the equipment is inputted, and JD’s details are provided.
