Changing Belt/
Bearing Service
Removing the belt is a special procedure that should not be rushed. Only replace the belt if it is slipping/damaged or if you need to replace the spindle bearings.
For this procedure you will remove the handwheel and mounting hub, hub adapter, spanner nut, out- board spindle bearing, end plate and speed sen- sor. You will also need to reset the spindle bearing preload and reinstall all of the components. Set aside approximately two hours to perform this procedure.
