10. Clean shaft and apply small
amount of Loctite on shaft at 1/2
inch from the tapered end. 11. Place small amount of Loctite on
exterior bearing race.
13. NOTE: If you are installing the
nut instead of the snap ring, nut
should only bottom out against
shaft shoulder. Do not tighten nut
so that it preloads the bearings.
Spin the disk and if disk slows
rapidly when tightening nut, back off
so that disk spins freely instead.
Any bearing preload due to the nut
will shorten bearing life. Loctite will
hold disk in place.

health effects, use Loctite in
