By the way, the manual states, in Step 38: "Using assembly lube, lubricate IMS Solution bearing and install IMS Solution flange into bearing by hand. Then using a soft face hammer, lightly tap the IMS Solution flange until is is flush with crank case."

Right. But when getting it the last quarter-inch or so to make it flush, I forgot about "lightly tapping." Making it absolutely flush required a couple dozen mighty blows with my 45-oz rubber hammer. After driving in the bearing and now the flange, my right arm is beginning to look like Popeye's.

I did everything I could to facilitate an "interference fit," as my friend the metal fabricator calls it. I kept the flange in the freezer overnight. The place I'm working in is unheated, but I placed a heater to direct heat at the opening for a couple hours, until the crankcase felt warm to the touch. I coated the appropriate surfaces on the flange liberally with assembly grease. I don't know what else I could have done. I think I was bitten by the machining-variance situation.
