Small Engine Crankshaft Arbor or Kart Rear-Axle Adapters allow our 9″ DYNOmite water-brake absorber to be installed on higher-torque engine applications, or even directly onto a kart’s rear-wheel hub. Arbors adapt crankshafts (that only have the small ¾”-diameter keyed shaft) to the 9″ water-brake absorber’s 3° taper-mount arbor. (Note: The engine’s crankshaft must be of a heavy-duty design to handle overhanging bending loads.) Axle adapters allow the 3°(1:10 taper mount) 9″ water-brake absorbers to be used for “in chassis” testing at the rear wheel. Available for many USA or European wheel-bolt patterns. Requires simple fabrication of an “anti-rotation” torque-arm stop (i.e. clamp on pipe). Sprocket ratios should be selected to run the engine and absorber at their appropriate operating ranges – see load charts.
