We designed the crank adapter to be used with ATI tool kit #918999 & Proform tool kit 66514. Both of these kits do not have the proper thread size crank adapter for Honda/Acura/Nissan/Mazda engines.

The tool kit & Doryoku crank adapters are use for installing press-fit (interference-fit) style crank adapters such as ATI & Fluidampr.

Both tool kit & Doryoku crank adapter are required for proper install & removal without damaging crank, damper.

You will need to purchase an ATI or Proform tool kit and purchase the correct crank adapter for your engine. Doryoku crank adapter includes three 5/16"-18 bolts & washer. The ATI or Proform kit will not include them.
