the transfer pto ran the hyd, and the 45000 drag winch on the wreckers, the output shaft on the pto connects to the transfer input shaft with a jaw clutch. if you add a transfer pto to your transfer, you MUST, i repeat MUST have the transfer oiling setup with it, other wise you WILL burn up the transfer for lack of oiling, the transfer gets its lub nomaly by gear pickup, but with it standing still this CANT happen, the oiling setup pumps oil from the bottom of the transfer to the pto houseing thuse lubing the transfer top gears and drip down from there.
with the transfer pto, it is run in 4th or 5th only, the rear wrecker drag winch has its controls by the winch to give it foward and reverse ect, the oiling setup ONLY works in the foward direction, other wise you WILL burn up the transfer for lack of oil
