I have yet to hear of someone who had a problem with installing a flywheel on a conversion and later had to remove it to rebalance or had vibration problems. I have read several posts of folks who used gasser flywheels and the like and had good results. This leads me to believe that mercedes flywheels are neutral balanced regardless of their origin. If someone has objective evidence to the contrary please pipe up. I find the speculation confusing. I have built high performance gas engines for over 30 years and usually there is clear direction from the manufacturer as to whether the particular engine requires external balancing or not. Please learn me about mercedes. Cheers Dan
