I didn't drop the crank, just loosened the main caps. I would remove
one cap, then use a small screwdriver to ~carefully~ start the old
top half out. Then you can shove the new top half in, making very
sure to get the tang properly lined up with the notch in the saddle.
I did my best to mike the crank, it seemed OK, but my bearings didn't
look too bad. One rod journal was a little rough - I could feel a
little material on it as I ran my fingernail across it, but you
couldn't see anything - so I *gasp* smoothed it with a bit of fine
emery cloth tape. Kids, don't try this at home... I went back with
standard bearings, since the crank seemed to be OK.
All things being equal, if I were to do it again, I would pull the
motor just to change the seals and do everything else while I was at
it. At the time, I didn't have access to a crane and engine stand,
but I do now...
