Installing a Fluidampr or an ATI damper pulley to your engine requires a tight interference fit. Due to that reason, the pulley must be pressed onto the crank and pulled off with an install/removal tool. This is a must in order to prevent any damage to your new damper or surrounding components.
These guys ended up having to do an emergency track-side engine swap that required the pulley to be transferred over to the new engine... Don't get caught without the proper install/removal kit!
The most popular install/removal tool kits on the market are:
ATI: #918999
Proform: #66514
When you purchase one of these kits to install your Fluidampr/ATI damper onto your Honda/Acura/Nissan/Mazda engine, you'll quickly realize that the correctly sized crank adapter is not supplied in the kit. That's where Doryoku comes in to save the day!
We designed the crank adapter to be used with the ATI and Proform tool kits. We offer a few different sizes depending on your application.
M14 = Honda B, D, H-series (1st Gen), and Mazda BP
M16 = Honda K, H, F, J, C series, and Nissan KA
This purchase does not include an install/removal kit! You will need to purchase an ATI or Proform tool kit separately and purchase the correct crank adapter for your application. Your Doryoku crank adapter purchase will also include three, 5/16"-18 bolts and washers that are needed for pulley removal since the ATI and Proform kits will not include them.
