5.1.12 Installing Angular Contact Bearings
(See Figure 16)
1.
On the inner race of the angular contact bearings, the thin walls face each other.
2.
When tightening the clamp nut, first engage a few threads. Then lightly tighten
the locking screw slowly, so that when you slowly thread the lock nut inwards
you can feel some contact between the two threads.
3.
Once the clamp nut is completely threaded inwards you will need to use a torque
wrench to apply 68 N-m. of torque, properly seating the bearings.
4.
Completely thread in the locking screw to prevent the lock nut from unthreading.
