Does anyone know what specific manufacturing changes were made that are reflected in the master parts list between '04/'05 & '06/07 for the following parts for the M112 (EGX) engine ? FLYWHEEL, CRANKSHAFT for the (DED, DGJ, DGU) transmission... There are very specific bolt pattern differences on the crankshaft between the NAG1 fitted engines and the 6spd manual which prevent mating of the manual transmission to the (EGZ) engine without utilizing another flywheel from a very specific MB model. I am thinking that the crankshaft bolt pattern was changed for some reason during the production run... any ideas ? And yes, the crankshaft from a '05 (EGX) NAG1 has the exact bolt pattern as the '05 (EGZ)... I haven't had the opportunity to view all the different model years, only the '04 (EGX) with the (DED) and the '05 EGZ with the (DGJ) I'm not sure of the (DGU W5A330) Any ideas will help this forum achieve the (EGZ) engine swap with the (DED) transmission without having to track down a MB flywheel / pressure plate from another model...
