The right parts, poor packaging.  The adhesive exploded and now I'm mulling over just using RTV for the tub seal.

For the bearing installation a large (5/8?) bolt and some washers/nut from the hardware store cost a few dollars but installed the new bearings just fine.  No need for the expensive tool, though it would probably be easier to use and be nice and snug around the edges.  Also might help with the tub seal, but right now I'm just cursing bad packaging.
