Used components are pulled directly from a vehicle – typically a junkyard vehicle – and generally not even so much as surface cleaned. There are no provisions for disassembly, internal cleaning, or inspection with a used component. Used or junkyard components may have high mileage and a poor maintenance history – a failure waiting to happen. Many used or junkyard components come from a vehicle that was involved in an accident and may have unseen damage.
To rebuild is to recondition by cleaning, inspecting and replacing severely worn or broken parts. Serviceable parts are reused within the manufacturer’s acceptable wear limits. The quality of rebuilt components varies widely and many come with only a short term warranty.
To remanufacture is to make as closely to new as possible. All core material – head and block castings, crankshaft, camshaft and rods – are carefully inspected, checked against original equipment measured specifications for correct dimensional tolerances and precisely machined. Replacement parts are new or requalified to meet exacting standards and tolerances. Testing is performed to manufacturer measured specifications and original production standards.Tags:
