Bearing cones and cups are designed to work together.
It is important to position them so bearing cone taper
mates with cup taper.
1. Lubricate new cups with a light oil. Place them in
spindle housing so they will mate with bearing
cones. Cups and cones are a press fit to minimize
wear.
2. Seat cups securely with a press or place a large
drift in the flat lip and drive them into housing until
cup seats against machined shoulder of housing.
3. Place bottom bearing cone into spindle with taper
positioned to mate with cup.
4. Identify the open side of the seal containing the
spring.
