WD45 Hydraulic pump

I'm sure this has been discussed a thousand times, but I am having trouble finding much information that helps. I am looking to run a fully hydraulic loader and have 2 auxiliary lines on my WD45. I have been trying to come up with a way to hook a hydraulic pump to the pulley on the front of the crankshaft without using a belt or chain. Has anyone done this? If so, can you please post pictures, descriptions, and/or links to parts?
 
It has been done thousands of times with parts to an AC 445 loader. There is a round disc with drive slots that gets welded into the front of the crank pulley for a drive connection. The manual hand crank shaft gets removed. The pump fits between the steering front support and the crankshaft pulley. It was a pretty neat set-up and the only thing you lost was the ability to hand crank the engine. If you find a 400 series loader manual that has 445 installation instructions, all the details are in there.
 
Back in the 70s I reversed a WD and mounted the loader over the rear axle. Tried three hyd setups, first was a double sheave pulley on the crankshaft...very hard to find- it comes from an AC power steering setup. Didn"t provide enough belt traction, and hard space to work in. Second was a large low pressure pump attached to a stub shaft welded into the center of the pulley, chain coupler drive. Third one that worked better was a small high pressure pump, with a chain coupler, and I added 6 inches to the front of the frame rails, giving me adequate room to work in.
