Rotor Drive Stub Shafts
Illustration 1 g00765581
(1) Stub shaft (2) Rotor drive sprocketThe right and left rotor stub shafts are identical. Stub shaft (1) is mounted to one end of the rotor drum. Another stub shaft is mounted to the other end of the rotor drum. The stub shafts rotate as the rotor drive sprocket (2) turns. The stub shafts then rotate the rotor drum. The bearings for the stub shaft are lubricated by an oil reservoir that is mounted on top of each chain case.Rotor Drum (Asphalt Reclamation)
Illustration 2 g00765582
(1) Rotor assembly (2) Bit (3) Bit holder (4) Left hand end ring cuttersRotor (1) is located inside the rotor housing. There are two left hand end ring cutters (4) that are mounted on the drum. There are two right hand end ring cutters that are mounted on the drum. There are a total of 188 bit holders (3) on the drum. Each of the bit holders contains one bit (2) for cutting the material. The cutter is driven by the two stub shafts. The stub shafts are driven by the rotor shaft sprocket. The rotor drum pulverizes the asphalt material and the base material and the drum mixes the asphalt material and base material. The rotor for road applications can be equipped with attachments for injecting additives directly into the mixing hood.Note: Optional rotors allow the rotor for road applications to be converted to a rotor for soil applications. The rotor for soil applications does not have a ballast or a breaker in order to do the same operations as a rotor for road applications.Note: Contact your local dealer for a listing of available rotors.Ballast
Illustration 3 g00765583
(5) BallastBallast (5) is added to the machine in order to distribute more weight to the rotor drum. The ballast is located under the mainframe directly behind the hydraulic oil tank. The rear tires can be filled with fluid for ballast. The front tires can be filled with fluid for additional ballast.Note: Ballast is added on machines that are equipped with rotors for asphalt reclamation. Added weight is not recommended for soil stabilization.Breaker Bar

(6) BreakersBreakers (6) are located in the rotor housing. As the cutter drum turns, the breakers break large pieces of asphalt into small passable pieces. This action maintains a more uniform pattern from the cutter drum as the rotor turns. Three breaker bars that are mounted in the housing run the entire length of the cutter.
