    Its just a regular right handed thread bolt, nothing special. An impact wrench usually gets it fairly easily.

        Had my harmonic balance wheel literally fall off and shear the bolt off in the crank the other day. Be carefull as sometimes they have locktight put on them at install. There are a few threads covering the removal on the site.
        Came across a few that indicated a bit of directional heat from a heat gun might soften the locktight.
        I would be carefull using this though.

          I used a socket and bar up against the chassis rail and gave the motor a quick crank for maybe half a second. Crude, but worked a treat. But, beware on the 4D56 you must do the crankshaft pulley up super tight as otherwise it can shift slightly altering the timing and damaging the slot in the crank, which results in an engine rebuild. (Ask me how I know)

            If you had some movement and then tight again it may be that the thread is seized. Be very carefull undoing it. Maybe work it back and forward a bit to see if that frees it up to undo.

                If you search in the gen 2 section there are instructions there on making a spanner of sorts to hold the pulley steady while tightening it
