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.
Our new tool is made of carbon fiber reinforced nylon. This avoids any potential scratches to the metal surfaces of the engine. It's also less likely to get dented or gouged while bouncing around your toolbox, which minimizes the chances of damage to the rubber seal.
Printed on our Markforged printer out of Onyx materal. Not only is Onyx strong, it's also highly resistant to chemicals such as oil and gasoline - unlike many other materials used in additive manufacturing. This new production method allows us to bring the price down while improving the part at the same time!
This part is for the "short nose" 1.6 engines, with a four-slot front crank pulley and a VIN of 209446 or lower. We have a separate tool for the later "big nose" engines.
