The identification of John Deere Parts sometimes, 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 simple was many, including myself, would prefer it to be.
To start with, lets begin with Truck Repair Manual water pumps. Using 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. Taking into consideration that we now have 4045, 4045D, and 4045T engines, the amount 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 many instances, the combinations of pumps would require further information. In this instance, the quantity which is casted on the old water pump is necessary. This is regarded 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 produced in Dubuque, without any turbocharger, may have a water pump part number of RE21177. The part variety of the housing is AR80109. John Deere will list both these numbers as using a casting number of R59049.
The turbocharged John Deere Technical Manual will have a water pump part quantity 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 even a water pump overhaul kit.
This casting number phenomenon is not restricted 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, in comparison with construction engines, could have slightly varying components. An engine block for the marine engine for that 4045 engine could be slightly distinct from the engine block to get a 4045 tractor engine. Both are designed for different applications, and can be different. Marine engines are specially designed for continuous operations.
To reply to the question as to if an engine block from your marine can be interchanged for the engine block from the generator, for example, a couple of things should be done.
One, compare the casting numbers on both blocks. This is embossed on the side of the cylinder block. If the two numbers are identical, then this interchangeability is achievable.
Two, compare the SAE housings of the two engines. It’s no use switching engine blocks around, to discover at late that the SAE housings will vary, and therefore, the transmission can not be bolted on.
While writing on the issue of Takeuchi Tl140 Workshop Manual casting numbers, other relatively simple information and facts are invaluable in identifying correct parts and part numbers. A simple as it might sound; the actual style of the equipment is needed. A 310 euyzoy is not the same as a 310G backhoe. The serial number of the equipment is additionally needed. A serial number will incorporate the engine model, and the machine type. John Deere’s online system provides a free service whereby the serial quantity of the machine is inputted, and JD’s details are provided.
