What is the difference between a rebuilt engine and one that has been “remanufactured”?
There are many levels of rebuilding an engine or related component, but basically they all follow the same method. In a rebuild situation, the product is normally disassembled only to the point of the perceived failure. It is then rebuilt, reusing some parts and replacing others with new ones. Generally, parts that are reused are cleaned and visually inspected before they are reinstalled. Remanufacturing is a much more thorough process. The first difference is that the engine or component is completely disassembled. Each piece part is thoroughly cleaned by either a bake or chemical cleaning process. All major engine parts (cylinder heads, blocks, and crankshafts) are inspected for cracks or damage using a Magna-Glo process. The part is then dimensionally compared against the original John Deere specifications for that part. Any part not meeting original factory specifications is either scrapped/recycled or brought back into conformance with spec using a John Deere-approved remanufactur
