Power Train Pressures with Output Transfer Gear
2WD and AWD Units
The output transfer gear maintains the same output speeds (constant 1:1 ratio) as the transmission output while providing for the ability to transfer the power flow between multiple output yokes for both stationary use by a work tool and vehicle propulsion. These pressures show a low to high acceptable limit along with the respective rpm variations.
