This 7/16in OD and 13/32in long aluminum spacer is used as a tool to properly space the pinon gear on a CIM Motor for the EVO Shifter and EVO Slim. Using an arbor press, press the pinion onto the output shaft of the CIM Motor until the arbor press bottoms out on the shaft. Then place this spacer on top of the pinion and continue pressing until the arbor press bottoms out on the shaft again.

If you’re looking to use the EVO Shifter or EVO Slim and don’t have access to an arbor press we recommend our CIM motor with pre-installed 15T gear (am-0255_15t).
