Description
Hunter RP6-710014120 Nylon Plastic Mount and Demount Head for Leverless Tire Changers
The mount and demount head (commonly called a “duck head”) is the plastic component that attaches to the end of the swing arm on Hunter leverless tire changers. When this head cracks or breaks from normal wear, incorrect technique, or excessive pressure during demounting, it must be replaced to restore proper machine function. This nylon plastic head mounts at the end of the arm and is compatible with Hunter TC3900, Auto 28, TCA28, Auto 34, and TCA34 machines – note that TCA34 fitment requires serial number 664 and higher.
