Bernie is right on both counts....give him his due...

(The timing belt will slowly loosen up over the next
few hundred miles, and have less tension anyway.)

btw, I had circlips on BOTH sides of the bearing, got everything
out but the bearing itself. The thing is just WELDED in the housing.
The hub is off, and the hub race is off, the circlips are out...
Trip to a good machine shop tomorrow I guess...
