using Power steering pump as Plow pump

I just got an old FIsher speedcaster plow and the under the hood hydraulics that it came will not fit under the hood my newer 2002 f150 4.6 4x4 so looking for alternatives. I electric hydro set up about 1,000 bucks! ouch so....ive read of others using the power steering pump ro run the valve. anyone else with any experience with this.......the best I heard and read is going PSP to Steering box out to the Plow valve and then back into Power steering pump.....so steering is always #1.........they claim success.

Thanks for any ideas....even if I found a spot under there no idea of how to run a second vbelt pulley of of to make it spin....!!!

Thanks all God I love this truck

Maybe they were talking about going from your existing power steering pump out to the plow valve and back to the pump.

When your not steering, the pump is just circulating low pressure oil back to the tank... So you would have to put the plow valve in series so it can push the low PSI oil into the cylinder and build up pressure instead of flowing back to the tank. If the two systems were in parallel, the oil would always flow thru the lower psi of the two systems and back to the tank.
That shoud work, but not sure its 100% road legal ?

how about just looking for a decommissioned plow truck that still has the pump on it and buy the truck. steal the pump

Dad was looking for a truck box, he ended up buying a someones junk truck. ripping the box off of it and selling the truck for the same price he bought it for, netting the box.
