Morning all,Has anyone had to replace engine mounts on the C12?Engine moves about 3/4” forward when throttling up. Forward mount shows significant flex.As I understand and am subject to correction, Cat has upgraded the new mounts to a 1” stud instead of the 7/8” previously used.This will be a problem to drill out the mounts without lifting the entire engine out.Anyone been able to do this?Also the bottom nut with “set screw” is that to tension the bushing or lock the stud in place from rotating?Looking forward to some feedback
