A compound transmission design for reducing gear hopout, particularly during PTO operation. In this design, a spindle is rigidly secured to an input shaft, and a headset/fourth gear is rotatably mounted on a spindle by means of a full compliment needle bearing. A splitter gear is rotatably mounted on the input shaft and includes a sufficient diametral float with respect to the input shaft to minimize tipping of the gear while maintaining significant torque balance between countershafts. This configuration maintains concentricity in parallelism of the headset/fourth gear and splitter gear with respect to the synchronizer clutch in order to prevent gear hopout.
