The key to making a good seal on the (nightmare) # 8 bearing project is cleanliness.
You really have to get a clean surface for the glue to bond to.
What glue did you use?
It a nice product but one problem we found with the Amon solution was a gap that can form when you tighten the set screws. The set screws in effect push the collar away from the bearing creating a passageway for the oil to leak.
Our solution was to fit each collar to the individual bearing perimeter and press/sweat it on.
This in combination with the Hysol 9340 seems to create a rigid /pressure resistant seal.
