Easy to use. Only gets 4 stars as I had to clean up some threads before use and fabricate a plate for the roller bearing to rest on to reinstall the harmonic balancer on a 92 302 SBF, otherwise the roller bearing and hex nut for tightening would have been to far into the HB to turn. The locking collar will/did loosen when removing from the crankshaft, leaving the smaller adapter to be removed separately.
