How Reconditioned Engines Are Forged?
If you ever wondered how reconditioned engines are built then go through this quick overview of the whole process.
First and foremost the core unit is stripped and brought into most basic form. All the auxiliary components and attachments are removed to the point that only the engine head and block along with sump assembly are left. After this initial dissection, these three main components are further segregated to gain access to internal-most parts like pistons, crankshafts, connecting rods.
At the end of this first phase, a stripped engine block is left in its most basic form, which is then sent for thorough cleaning. In most cases a specialized hot wash system is used to scour away any grease from the outside or inside. It is only after this phase that the main block is sent for assessment, If engine block is deemed feasible for rebuilt or recondition, only then it is forwarded to the next phase.
In third phase of reconditioning the engine, it is sent to machining department. This department examines the basic unit to the extent that even cylinder’s wall dimensions and oval-ness are measured. This segment is of vital importance as at the end of it engineers and mechanics can approximate, realistically, regarding the amount of work needed to bring engine back to working condition.
In the fourth stage of reconditioning, mechanists start hammering their hammer on disfigured components, metaphorically speaking, in reality high-end machines are used to grind and polish engine block. In pure mechanical and technical terms this means either using bigger, oversized pitons along with similar ring sets or simply improving size of block to create a better fit with cylinder sleeve. Now, opting for the second option is favorable as it aids in bringing engine back to original factory specs; this allows use of more economical and more readily available genuine spare parts for the engine.
Concurrent to this fourth machining phase, other engine components which have been separated a while back are also being subjected to similar scrutiny. Connecting rods and pistons are separated; square-ness along with straightness of connecting rods is closely monitored, whereas piston rings and crankshafts are checked for wear and tear after cleaning. These components are often replaced, if found out of tolerance range or too badly damaged, otherwise they are just polished.
Once these intricately complex phases are completed, actual rebuild of engine starts. Engine block is integrated with all other parts to bring it back to its functional form.

The advantages of reconditioned engines
Throughout your life you will undoubtedly own numerous vehicles. At some point and time you may find yourself in a position where you have to replace the engine in one. When this eventually happens you will have to decide what type of engine you want to replace the original one with. The two main choices available these days are either a second hand unit or a reconditioned unit.
If you are not planning on keeping the car after it is repaired you may elect for the slightly cheaper option of a second hand engine. Bearing in mind you have no way to tell what the actual mileage of the engine is or the driving habits of the last owner, that lends the second hand option better to a repair and sell scenario as most second hand engines come with a short term warranty if any.
If you plan to keep your vehicle you should seriously consider the benefits of replacing the faulty unit with a reconditioned one. In general a reconditioned engine is virtually brand new inside so in effect it has zero miles on it and it will have the potential of having the longest life span if looked after properly.
A standard reconditioned engine has had quite a bit of work done to them in order to be able to offer a longer warranty and is a smart choice for those who take pride in their vehicles and would like to keep them for as long as possible. At a minimum machine work will have been done to the engine block and cylinder head in order to ensure they have flat mating surfaces, cranks are machined, polished or replaced as necessary new bearing sets will have been installed in both the connecting rods and main journals to ensure optimum oil pressure can be achieved, the pistons will have been fitted with new piston rings to create a positive seal in the cylinder chamber, cylinder heads will have been pressure tested to make sure they do not have any internal cracks, New oil seals will have been fitted to make the unit oil tight after all is reassembled the engine should be fit for purpose and provide a dependable replacement for your faulty unit.
All reconditioned engines should be “broken in” gently. This means that you do not want to hop in a vehicle with a reconditioned engine in it and immediately go out and put your foot to the floor on every occasion. The break in period is very important to the longevity of the new engine. At this time all of the new metal components ( rings and bearings) will slowly wear themselves in to their adjoining parts so all surfaces will mate and work optimally in the future. If the break in period is ignored you can actually shorten the life of the replacement engine and cause conditions where the oil pressure will be too low or the piston rings will not seat properly causing the replacement engine to burn oil.
At the end of the day, if you choose a reconditioned engine as a replacement for your original, it can last you the life of the vehicle if it is taken care of properly.
