Did some more to the valve mechanism this morning. Got some 1/2" key stock yesterday and made up the levers for valve actuation.

Also got the links made. Time to drill the plate so I can locate every thing.

I got the holes drilled in the plate, but curtailed anymore work! My hand is s.l.o.w.l.y getting better. But I felt further work today would set me back. I'll get the plate cut and the spacers welded on soon.

I'm joining this party late, don't sweat any side load on that pump ! It can handle it. That is a side gear load on the one pictured with the gear on it, ain't no belt gonna put a load on it like those helical gears will... You can drive that pump any way you want, it's plenty tough in the front.

Better late! Glad to hear from you on this. That will be a big help. Now, how best to hook lines to it. I could buy one of the line sets for it and put JIC fittings on the tubes. Or have a plate made with threads. Then, I need a reservoir. How big there? Of course a filter on the return line.

I can take the PTO off the engine and put a 3" pulley there for the pump. Put a 5.5" pulley on the pump and that should keep me under the 2000 RPM Max. for it. Only use I can see for the PTO is if I made up a shaft for rear PTO and the front axle is in the way of that.

Adapting the pump lines is easy enough, you just need to get it flat and the holes dead on. You can thread the holes for SAE straight thread ,remove the oring screw down tight and silver solder them in to seal them. They will never loosen or leak. And you don't need a special tap, SAE threads are standard sizes and tpi's.( threads per inch).
P.s. jic threads are the same...

Would that be a different tap than for bolts?

  Won't the tapped hole big as big as the flat face for the O-ring ?  Maybe your plate is thick enough .

I have a small machine shop close by. I think I'll take it by and see what he would charge me to make that plate. I have a piece of 5/8 bar stock that is could be made from maybe.

My hand felt much better today and I wanted to get this valve set up for Alice. Lots of intricate welding in close spaces! First was getting the RH valve mechanism ready to weld.

Next was to get the handles made up and oriented right.

The left handle (in this orientation) will be for the 3-point. It is welded on a 1/8" IP bored for the 5\16" main shaft.

Got that set up and saw I needed tighter pins holding the linkage. Tried drilling the existing and they were way too hard. I found some other pins (softer material) and set them up for this. It's fun drilling 1/16" holes.

I'm ready now to weld the other block to the main shaft. This will not be broken down again from the plate the valve mounts to.

Tomorrow morning I will finish welding it together and get some paint on. Then it's making a new mount for Alice!

Got everything welded on the valve handles! Even got some Rust Reformer on it.

I just talked to my daughter here in town. Her hubby is a machinist. I'm taking the pump and a fitting over to them this weekend and he will get the plate made for hoses to attach. May have to wait for a machine to finish a job it is on, then they will run this part before the next job starts.

Now to get a kit for this valve and see what is wrong inside. I tried it on Alice and could get no lift.
