Out of stock


The Viper CNC pinion tool is a very useful tool for installing and removing HO scale slot car pinion gears. This CNC machined gold anodized tool is made to install a pinion gear by putting it into one of the three recessed pockets on the handle and then pressing it onto the motor shaft. The other end of the tool is made to gently pry the pinion gear off of the motor shaft. Make this the last pinion tool you ever buy!

Includes:  1 - CNC pinion install & removal tool.

  One or more of the nub holes may need to be honed to a larger size since the pinion nub size can vary depending on the brand.

    Seems well built and works as expected. I thought it would be bigger, it is a lot smaller than I thought it would be, but it needs to be.
