Well, the only thing I would worry about is whether there's something different about the Clevelands that would absolutely require preload. Both the different wheels I've worked with have snap rings to hold the bearings in place, so I suppose if the Clevelands didn't have such a ring they'd probably need some sort of preload. However, looking at the exploded diagrams in my ACS catalog, they *do* have snap rings. The only other possibility, then, is that the preload is required so that the brake/disk relationship can't change. But I've never noticed any real side-to-side play in my wheels, and can't believe the Clevelands would be that intolerant. I'll ask my local EAA Tech Counselor to see if he has any insight on it....
