OK, I have messed up somehow, I took all the engine tin off, the fan and large fan shroud etc., had stuff powder coated and cleaned. Started putting things back on last night and the fan is not centered in it's hole, it is touching on the alternator side. What has happened?

I thought that if you tighten that bolt beyond spec (probably would have to be way beyond) it would pull the hub further onto the crank, pushing the hub against the first bearing on the crank, which would pull the crank forward, which would pull the flywheel forward against the endplay shims and rear main bearing. Or, maybe just pull the hub forward on the crank enough that the fan bolts are pressing against the crankshaft seal at that end. Looking at this picture, it seems like either one could happen.
Did you forget washers behind the heads of the fan bolts (are there any)? Without those, the bolts could be simply digging into that seal causing your problem. -Chris Attached image(s)
