After engaging or disengaging shifters, constant pneumatic airpressure is not required in VAS Gearboxes as a separate ball spring assembly isinstalled in the shifter assembly to LOCK the shifter shafts after shifting.Pneumatic air pressure is only required to shift (engage or disengage) theshifter shafts, after shifting, pneumatic air pressure can be removed.
Both Driveline throughput (vehicle in motion) and PTO Aux. Applications cannotbe engaged (operated) at the same time. Either the vehicle shall run on theroad (Driveline) or in a stationary position the PTO Auxiliary Outputs can beengaged. This VAS Unique feature eliminates the possibility of an auxiliaryapplication accident while vehicle is in motion. If Both Driveline and PTO Aux.applications are required (to be operated) simultaneously, kindly refer to our Combination Reduction models CR4, CR7 & CR8series gearboxes which have both driveline & PTO Aux. simultaneous optionswith Reduction Driveline feature.
