Description Chassis Engineering has developed a mobile press for Liberty Transmisson Head Gear Sets. This press design alleviates the need to use a hammer, sleeves, sockets and blocks of wood to maintenance or change gear sets. The Chassis Engineering Head Gear press allows for the removal and installation of head gear sets.  It presses the gear set off and back on without damage to the shaft, gear set and/or you. Turnaround time between rounds is seriously reduced. Tools needed are an impact driver and socket.
