At 18,560 Miles on my 09 400, I plan to remove the covers and check my Belt for wear. clean, Etc. before Spring arrives. I plan to order a new belt just in case it is needed but I wonder if the Rollers could need to be replaced also. How do I determine if they are worn? I cant find any dimensional reference to them as a checking point. The OEM Rollers are 19 G But I read several posts that indicate lowering to 18G is advisable to reduce RPM. Any advice and comments is appreciated.
