1. Pull out cone shaped adapter piece (tap out or use pliers). 2. Pull out internal adapter from inside shaft by screwing in an 8MM hex bolt. Once bolt is firmly screwed in, pull or tap out. 3. Install new internal adapter into shaft. Ensure the machined end of the adapter is inserted first. Machined end will have smoother internal grooves when viewing from the end. 4. Install/tap on cone shaped adapter until it bottoms.
