ABSTRACT:
A power take-off is configured for use on four wheel drive trucks with automatic transmissions and chain driven transfer cases. This power take-off replaces the conventional adapter used between the transmission and the transfer case, and requires no modification of either the transmission or the transfer case. It is driven from the transmission output shaft and can provide power for the operation of an item of auxiliary equipment such as a hydraulic pump or air compressor either with the truck moving, or while the truck is stationary by placing the transfer case in neutral. Since this power take-off requires no modification to the vehicle other than the addition of a shift-wire to a control knob in the cab, it can be readily added to trucks already in use, or offered as a dealer option on new trucks.
