                             Damper Plates  ( torsional couplings )    and  Oil Coolers


                           Damper Plates  (Engine Torsional Couplings )  come in many styles and capacities,  depending on engine  and  transmission.  The            

                        damper plate  (torsional coupling)  come in many forms, often mounted to flywheel  and assist in turning the transmission while                                      attempting to help isolate transmission from some damaging forces and torsional noise.   Both Gasoline and Diesel engines create          

                        torsional forces, especially at low RPM, making transmission rattle and knock.   The proper damper plate can help assist in reducing        

                        torsional noise, while helping to protect transmission.   Often times, and in particular with Diesel motors, transmission manufacturers        

                        recommended the engine manufacturer  perform a torsional analysis  on motor,  and choose the torsional coupling they prefer after       

                        analysis.Damper Plates are not a cure for engine torsional loads and noise,  but are required, and assist in different ways.                        


                   Many different  types exist.   Below are a few examples.   There are many more

                         Most Marine Transmissions require cooling  (there are a few small mechanical ones that do not )

                  Proper oil cooler is important, as well as the quality.    We offer high end  top quality coolers.    There are many sizes and needs

                                Below are some examples
