The new plan was to incorporate some small 1/8" quad rings to act as seals but decided to go with o-rings instead. (less contact area making it easier to turn)
The "inner race ring" will be installed upside down and an o-ring added to seal against the inside face of the shoulder that supports the 100 - 1/4" balls on the stationary outer race. (Sorry the photo shows the quad ring)
A new taller top spacer ring was made with an o-ring installed that will seal up against the ID of the sprocket.
The new top spacer ring also needed to be a bit bigger in diameter to match up with the original ID of the sprocket.....Yikes....just enough clearance for the balls once the angle was cut on the spacer.......fun fun......more obstacles!!
