Generac 0K4649 Mixer Assembly w/ Stepper For 22kW Evolution Air Cooled Generators. The stepper motor cannot be ordered separately if it's bad, must be replaced as an assembly.
It's recommended to apply a small amount of silicone lubricant to the 2 small O-rings that seal the mixer onto the intake manifold so that they are not damaged when re-installing.
These mixer assemblies are specific to the serial number of the generator! If you would like to confirm correct fitment, please send your serial number so that we can confirm you are getting the correct part.
