Water in oil/brown smoke

[Greg Smith]

The pilot bearing tool is indeed a set of three
outward facing hooks like a gear puller.  They are J
shaped.  There is a tapered cone on the shaft that
slides against the end of the J hooks and forces them
outward; holding it in postion inside the pilot
bearing.  At the end of the shaft is a 1 or 2 lb
weight on a slide hammer setup.  A few quick smacks
outward and the bearing generally releases intact from
the rear of the crank
