    I have an RCD crank hub going on a BBC with 1/4" dual keyways. Looking for the nominal press fit number to avoid any fretting between hub and crank.
    Thanks in advance.

    I believe my press for .003-.004 under sized on the hub. Always had to heat it up to put it on. Once it was warm she slid right on with the installer.
