After resting the bolt in the TL-CJ40 tool, if you can't insert the cable through it and then insert the bolt into the pulley… you have the wrong bolt. The Alfine SL-S7000-8 shifter works with the Nexus (same pull), but the bolt won't (easily) fit into the pulley for that reason.

The reference number for the Nexus hub is Y74Y98030, to be used with a CJ-8S20/CJ-8S40 cassette joints. If you bought an Alfine shifter to use with a Nexus instead of a Revoshift, the bolt can be purchased separately.
