Identical to 40 Series Driver (203015A), but has two idler bushings on the post surface to prevent “engine creep” (see secondary image).
The model 40 is sometimes referred to as the “Mid-Range” torque converter systems since it falls into the middle range between the series. The model 40 is a rugged piece of machinery. The drive clutch is composed of heavy walled stamped steel to withstand the extreme rigors of rough applications. Whenever there is a need, want and use for a torque sensitive drive system device that is infinitely variable from engagement to the highest speeds attainable (within the pitch diameter range), the 40 model system should be considered.
