What is different about rebuilding and remanufacturing?
Typically a rebuilt engine or transmission will have a much shorter life than a remanufactured unit because the process is much less precise and, therefore, less predictable. Here are a few key differences: Rebuilding is done mostly in local shops. Each job is handled differently and depends upon the judgement and skill of the individual mechanic. Parts believed to be serviceable are cleaned and reused to the maximum extent possible. Only worn or broken parts are actually replaced. If reused components subsequently fail or break, diagnosis and repair can be very costly. Remanufacturing is a factory process. It starts with a sound, undamaged engine or transmission core that is carefully cleaned, conditioned and machined to OEM (original equipment manufacturer) tolerance specifications. All wearable components are systematically replaced with new parts including pistons, piston rings, valves, lifters, or in the case of transmissions, torque convertors, clutches, etc. Remanufacturing is s
