1. We tear down the used engine assembly completely and always discard pistons, bearings, seals, gaskets, timing gears, chains and many other parts. These discarded component parts are replaced with new, high quality parts when the engine is re-assembled.
2. We thoroughly clean all retainable parts, using the latest cleaning technology.
3. All components are completely inspected for defects. Those not repairable are scrapped.
4. Cylinder blocks are bored to uniform size and tolerance, then precision honed to achieve a superior micro-finish.
5. Cylinders receive new pistons and rings that are select-fitted to achieve exact piston-to-bore clearances.
6. All connecting rods are re-sized. Then they are ground, precision honed, and brought to O.E. tolerance.
7. Each engine is assembled on a progressive assembly line where every operation is monitored for proper assembly, fit.
8. Each camshaft is re-centered and the lobes are re-profiled. After grinding, all journals are polished and the lobes are Parkerized.
9. Each cylinder head is cleaned and inspected for cracks or other defects. All head surfaces are machined to eliminate warpage and nicks and to ensure proper surface smoothness. Valve guides are replaced, if necessary. New re-manufactured valves, springs, and seals are installed, and all valve seats are ground to provide perfect seal.
10. The crankshaft is re-centered, realigned and checked for balance. In addition, the main and rod journals are re-ground and polished to an exact micro-finish standard, and all oil passages are cleaned.
11. Each completed engine is checked by precision spin-test equipment. The valves are rechecked for proper adjustment. Each engine is checked for proper oil pressure, oil flow, turning torque, and compression.
12. Throughout the re-manufacturing process, quality checks and testes are performed by machine operators, assemblers and our quality control department to assure that engineering specifications are maintained.
