Did I screw up?

84 1.6 N/A. I was putting in my IM shaft bearings today and on my first go with the rear bearing I didn't get the oil hole lined up quite right, so I pulled it back out and re-installed with the oil hole lined up correctly. I was wondering if it will hurt anything having installed this bearing twice. It did seem to slide in easier on the second go round, and I'm wondering if these are a one time use thing like so many other VW parts are. Will it be susceptible to spinning having been run through twice like that?

Unfortunately it is quite possible that it could spin... Typically bearings similar to these are only good to be pressed in once....

 8)There's one trick you could try, if your supplier is out of reach:
Pull bearing and using a spring punch make a series of punch marks all round the outer surface of the bearing. This will create mini mountains that will increase the diameter of the bearing, tightening it up. Same trick for the taper bearing stub axles....

I kinda figured I'd need to replace it but I wasn't sure so thought I'd ask.
Andrew I followed your how-to step by step but I made one mistake. I didn't make my bearing installation tool long enough. I just stuck a tape measure down in that cavity to give myself a ballpark figure on how long it should be and settled on 1 1/4 inches. When I put my blue tape on there to mark the hole I had to leave my tape hanging over the the end of the installation tool far enough so that I could see it through the hole in the block. When I went to press the bearing the tape got all crinkled up and that's what led to my mis-alignment. I was off by about half the width of the hole. On the second go around I reached in from the front side and made sure the tape was pressed up tight against the outside of the bearing cavity, it worked great that time.... Hole perfectly aligned. Have to chalk that one up to experience. At least it wasn't a hugely expensive mistake.
