1 PROBLEM PROBLEMS The auxiliary transmission of DF4A and DF4B locomotives are respectively driven by the output of the diesel engine and the output of the free end. At the free end of the diesel engine, the crankshaft directly drives the hydrostatic transmission via the transmission shaft. Both ends of the transmission shaft are respectively splined shaft and splined shaft of the spline sleeve and the free end of the diesel engine, and the spline shaft input by the hydrostatic transmission Connected. Drawings require that the pump drive be forked
