A slick little part designed by Flyin' Miata to ease maintenance. Slip the tool over the crank nose, install the crank bolt and tighten up. The crank bolt pulls the tool in. The design ensures the front seal slides perfectly into place, but cannot be pushed in too far. A perfect installation every time. A great part for anyone who does their own maintenance or for clubs.
This tool is for the 1991 "long nose" engines, with an eight-slot front crank pulley and a VIN higher than 209446. It also works on all 1992-05 engines.
