The stupidity of this design is mind-boggling. Import engines,
especially Toyota, all have slip-on dampeners, with a couple 10's
clearance. There is absolutely no need to have a press fit, except to
demonstrate their inability to machine the crank and dampener to such
close tolerance.

Press fits require pretty much the same tolerances, just on the negative
clearance side. I'd say it has a lot more to do with eliminating the
cost of milling a key slot, broaching a pulley, and providing a key....
But otherwise I totally agree.
