12:1 CIM Sport with 1/2 in. Hex Output

The gearbox has a gear ratio of 12:1 with a ½ in. Hex Output. A free packet of red tacky grease (am-2768) is included with every gearbox purchased. This grease must be used to coat every internal surface of the gearbox before use.

The CIM Sport includes mounting hardware to attach any CIM style motor or gearbox. To install one of these motors, press on the included pinion gear using an arbor press. This press fit ensures a solid mechanical connection between the pinion gear and the motor. This pinion assembly is not susceptible to vibration, and never needs to be checked once installed.
