  I was about to start my new engine today and when I filled the
radiator the water pump sprung a leak so what better time to fix the
pulley.
  The sleeve is .250 wall and has a slight interference fit so I had
to heat it and then it slid on with a couple taps with a mallet, also
I put epoxy on the pulley before I slid it on.
  I found that the pulley was .004 out of round and I measured two
other pulleys and found that there was up to .030 difference between
them so it would be best to these custom fit for each pulley.
