The preferred method of installing bearing cones is to heat them to
approximately 250°F prior to installation. During this operation protective
gloves should be used. Once bearing cones are installed in correct position
they should be allowed to cool before proceeding with assembly. As an
alternative, bearing cones may be pressed into position providing the proper
equipment is employed and the necessary procedures are used to prevent
component damage.
Under no circumstances should bearing cones or cups be hammered
into position.
For torque settings of fasteners and shaft rolling torque, see section 5.2.
