Breathing New Life Into an Aging Engine
Remanufacturing an engine is a way of reviving it. What makes this process different from simply fixing it is the completeness with which it is carried out. In a remanufacture, the whole engine is taken apart, inspected and cleaned. The dilapidated parts are repaired if their condition allows; otherwise they are replaced with new parts. Specialized machining is carried out to make sure that every part works perfectly. Some machining includes reforming the piston-cylinder system, and smoothing and lubricating bearings. The crankshaft can be reground, and all connecting rods are machined and specifically gauged. Once the process has been completed, the engine will work like a new one.
Overhauled engines are different from remanufactured ones because they have very few parts that are replaced and there is hardly ever any machining. That means overhauled engines are not as reliable when it comes to lasting a long time. Rebuilt engines are crafted to meet the latest Original Equipment Manufacturer (OEM) specifications. Since these could have changed since the engine was initially produced, with the improvements the reconstructed one may actually run more smoothly and efficiently than the original. Due to the laborious process with which they are recreated, manufacturers are willing to back them up with warranties. They function like new units, but at a small percentage of the cost. They are tested, inspected and certified to function like new ones.
If the engine of a car or boat is experiencing major problems, then replacing it with a remanufactured one is the most economical way to extend the life of the vehicle. Another reason for replacement with a remanufactured model would be if the original has exceptionally high mileage, often considered more than 100,000 miles.
