What is a Re-manufactured Engine
A remanufactured engine is exactly that – an engine which
has been returned to the manufacturer’s specification to provide levels of
performance, reliability and life similar to that of the original engine.
It is not a "replacement", "exchange" or "rebuilt" engine.
The British Standard Automobile Series Code of Practice
BSI AU 257:2002 fully details how for spark and compression ignition
(diesel) engines, components shall be inspected and checked against
manufacturers tolerances. Key components including piston assemblies, big
and small end bearings / bushes, gaskets, seals , timing chains and drive
belts are renewed whilst items such as tensioners and dampers are checked
and replaced where necessary.
Important additional operations such as crack testing
machined components or deburring reworked oilways ensure original
performance is achieved with reliability.
As well as having all key clearances, tolerances and end
floats checked after assembly complete engines are also required to be
checked for oil pressure and compression.
Finally, remanufactured engines offer the additional
advantage of having their own unique serial number stated in the
accompanying documentation which details renewed components, completion
date, test records and relevant instructions.
