Tip
When replacing the rollers, clean the cage and check it for damage, e.g. run-in marks, rough spots etc.; replace components if necessary. Worn cages or tapers can considerably reduce the service life of the rollers.
Taper
Unscrew the clamping screw (8) and pull the taper out of the sleeve. Remove the dowel pin (7). Pull the mount out of the taper. Remove the cup-spring assembly. Grease the cup springs and the mount during assembly.
