Front Loader from a Ford Truck

I don’t think a 120 FP torque hydraulic motor would ever work. The gas engine had the transmission which was probably like 5-1 in first.

Agreed. Double or quadruple that for a start.

If you want to convert it to hydraulic drive instead of using the existing manual tranny, I have this to say..... don't do it. It's silly, and you'll have a heck of a time figuring out how to regulate your speed forward and reverse with valves, "a pump" and a hydraulic motor. Plus, you'll lose a lot of engine power in the equation.

Go to a pick-your-part type junk yard and get an auto tranny for $100 and be done with it. You'll have thousands of dollars in a variable volume pump, hydraulic motor, valves, fittings, adapters, hoses, build-up, tear-down, re-do etc.... VS the auto tranny for $100.

You could also look into converting the transfer case to give it lower gear ratios, so you can put taller tires on it and still have power to turn them. 4x4 rock crawler type websites have lots of good info about that.

There's lots of fun stuff you can do, but by the end of it all, unless you acquire it all for nothing, you're gonna be right up there with the price of a decent used tractor that'll work better for that task.

But a fun project, nonetheless! Good luck. :thumbsup:

For getting hydraulic power for you loader cylinders off of your Ranger engine, I'd look into either a pump that mounts in front of your engine off of crank pulley like trash trucks use to power the compactor, or, I'd look at a clutch pump that mounts in-line with your serpentine/v-belts to the side of your engine. It's got an electric clutch, so you can start the engine without any hydraulic load, then switch it on. Increase your engine RPMs and you have great hydraulic flow and PSI.

Here's some examples. There are cheaper one's out there, but this gives you a start...

I wouldn't mess with a clutch on the hydraulic pump. All the tractors I've owned run multiple gear pumps and are direct drive from the engine crank in one way or another. Just leave all spool valves in neutral when starting.

I agree this project will cost far more than intended due to re-designs, broken parts, and all the little stuff, but that horse has already been beaten in the first thread!

Have you ever added a direct drive hydraulic pump to a Ford Ranger engine? I'd bet it's not an easy task. By using a clutch pump, all you'd have to do is remove the air conditioning pump, fab up the brackets, mount the pump and get a belt of the appropriate length.

OR

Get a double pulley for the alternator, fab up some brackets, and run it off of a V-belt off of the alternator.

I haven't, have you? I just don't see the need for a clutch, all things equal.

No I haven't. I was wondering how hard it would be to fab up the brackets and a coupler. I have added a clutched air compressor to a truck a long time ago. It was pretty simple. A clutched hydraulic pump would be exactly the same.

My currrent machine has three pumps directly coupled to a 25HP Kohler engine; one on the regular crank shaft and the other two on a PTO stub off the opposite side of the crankshaft. It's very hard on the starter in the winter to crank it over with cold hydraulic fluid. Very hard, but it starts down to -5F, but barely. Not too bad in summer, though. Based on that experience, if I could clutch it out, I would. There's a clutch kit available for a Kohler, but it would add length to the setup that I do not have room for in my engine bay, and since I have pumps on both ends, I'd need two clutch kits. I could get a stacked pump and put all three pumps on one side of the motor, and clutch that, but it would still add length to the setup that I don't have room for.

The clutched pump for a pickup truck engine is pretty darn cheap and belt driven VS a pump directly coupled to the front crank of an engine. The belt drive provides an easy coupling, while a direct coupled pump would have to be connected to the front of the crankshaft on the Ranger. There's not enough room between the crank and the radiator to put a shaft out the front, so you'd have to relocate the radiator up to clear the shaft.

Now I did find this picture on the internet of a belt driven hydraulic pump that appears to be driven off of a double alternator pulley on a tractor engine. There's no clutch and its belt driven. That would be another option on the Ranger if he wanted to skip the clutch.

That’s probably how I’d do it. The biggest problem I see is the alternator has a wide range of rpm with the upper end too fast for a hydraulic pump.

That's another reason why a clutched unit on an automobile engine would be my preference. You can shut it off if you have to run the engine at high RPM for some reason.

I just wonder how the Ranger's engine would work as a loader with direct drive of the wheels, which means huge RPM swings, which means intermittent power swings on the hydraulics.
