THE AEI REMANUFACTURING PROCESS:

•Quality Control Because your product has to last an intensive process control system is used to monitor all aspects of the remanufacturing process. Components are inspected after each operation and procedure. Only the highest quality parts and machine work are provided.

•Engineering At the engine remanufacturing plant, extensive research goes into casting numbers, machining processes and tolerances, new replacement part vendor selections and product applications. In addition, operators go through training that focuses on unique product features and processes.

•Disassembly Each core is disassembled and inspected. Those components not suitable for further processing are scrapped. All small parts are cleaned and critical tolerances are checked. Worn unusable parts are scrapped and replaced. All major components (crankcases, cylinder heads) are baked in gas-fired ovens to carbonize grease and dirt. Other components are chemically cleaned. Baked Components then go through an abrasive blaster that removes contaminants. Crankcases and cylinder heads are all magnafluxed to check for any cracks not found during visual inspections. Each component then moves to its respective matching area.

•Crankcases All freeze plugs are replaced. All holes are tapped and drilled; oil passages are cleaned and repaired if necessary. All cylinder bores are measured and taken to a uniform dimension. Diamond cutting hones are used for final bore sizing to ensure that surface finish requirements are met. New cam bearings are installed and checked for free cam spin. Crankcases go through a final wash to remove any remaining contaminants from the machining process.

•Crankshafts All crankshafts are checked for straightness before any further processing occurs.
Excessively worn journals are welded, reground and polished to process standards. Reground journals are blended with the fillet radii to remove any stress risers that could result in crankshaft breakage. All oil holes are chamfered at the journal surface to remove all sharp edges that could impede oil flow or damage bearing surfaces. Crankshafts are then re-inspected and belt polished to the proper RA finish of less than 12.

•Connecting Rods Each connecting rod is checked for cracks, damage and straightness. All crankshaft bores (big end) are resized to new specifications Where applicable, piston pin bore bushings(small end)are replaced.
Center-to-center length is then measured to ensure process compliance.

•Camshafts After cleaning all cams are inspected for straightness and lobe conformity. If grinding is required, the cam contour and timing is maintained to original specifications. All lobes are polished to ensure uniform surfaces and smooth performance. All reground cams go thru a “Parkerizing” bath to provide a proper finish for the final step. If non-remanufacturable, new cams are used.

•Cylinder Heads All aluminum cylinder heads are pressure tested to verify water jacket integrity. All cast iron heads are magnafluxed for cracks. All head gasket surfaces are inspected and machined as required to reach required specifications. All valve guides are replaced. Valve seats are re-machined with 3 angle cuts for proper flow. After assembly, each valve is vacuum checked to ensure proper seating and sealing.

•Final Engine Assembly & Testing All engines are hand-assembled by experienced technicians. Engines are live tested for correct oil pressure, oil flow, vacuum pressure and compression to ensure that your newly remanufactured engine will provide years of service.
