I'm going to go remeasure. I'm getting almost no diameter difference from bore to shaft. When I put WD-40 on and slide on very carefully I can't feel any radial play sort of like a slip fit. I think this lubrication location is a tough one as the idler doesn't move much just rotates a bit back and forth and there is only the one oil hole in the middle. Also the forces put a constant torque on the two bushings one up and one down.
I also notice that the idler sprocket doesn't seem to be running true with the chain all the wear is on one side....sort of like it is not floating to the middle like it is reported to do per the design.
