To Install The Drive-Side Crankarm
When handling the seals, avoid bending them. A bent seal will rub on the bearing, creating
drag.
1.
Apply a light coat of grease to the bearings on the face and the axle contact surface.
2. Apply a light coat of grease to the metal inside of one bearing seal (Figure 14.18).
