Default Re: Installing Rear Hub On A '40

Friction is the answer here. Just like a tapered collett or bit for milling machine or large drill press or even ball joints. The nut is there to keep it together and provide that a force is always keeping it in contact. The keyway adsorbs shock and does transmit part of the load depending on how much "taper friction" is available. Valve grinding paste is good for lapping the hub to the axle shaft to provide a full contact surface. Clean off the grinding compound and clean completely and dry. Assemble and be happy for doing a good job.
