Remanufactured Industrial Engines

The Difference Between a Rebuilt Engine and a Remanufactured Engine
This is probably the most confused term that is used in the engine replacement market today. A rebuilt engine is NOT the same as a new remanufactured engine. We have already shown that a new remanufactured engine is actually better than a new engine. A rebuilt engine is significantly different than a new remanufactured engine. A rebuilt engine is an engine that is just fixed, some parts replaced, and shipped to you with a limited and fine print warranty. What exactly does this mean?
Cheap Rebuilt Engines
An example of this would be if the engine failed due to the main bearings going bad, then a rebuilt engine will have the lower end parts that failed replaced. The upper part of the engine with the old parts would not be replaced; they would just be cleaned up. An example would be leaving the old cam, cam bearings, valves, springs, etc. still in the engine and not being replaced while the lower end got new bearings.
The advantage of a rebuilt engine would appear to be the lower price. The problem with this is that the quality of the engine along with the longevity of it is drastically reduced. Most rebuilt engines typically last maybe one year or less and the warranty has to be looked at very closely to find out what loopholes’ there may be. If you want to replace the engine of your vehicle so you can turn around and get rid of it, then a rebuilt might be an okay option. If you are looking for reliability, high quality, a true warranty, hassle free operation, and longevity then a new remanufactured engine from is going to be your best option.
