Knuckleboom crane upgraded to an electric motor for the hydraulic system

What size is the pump and what is it? Gear or vane?Single or double? Just asking because I know how H.P. requirements rise with relatively small increases in pump size.
Have you thought about a Diesel flush on the engine and adding Morey's?

yup, it can definitely lift... I was able to lift the All Terrain Track Chair with the boom extended about 2 feet, and that thing weighs 4000 lbs. Will it lift as much as the PTO drive? Probably not, but good enough for my purposes inside the shop. Also, the way the valves are constructed, I could move the boom to where I want it, and then use a chain block for the actual lifting. Lots of ways for it to be useable.

It's a 3 hp electric motor, with a speed reduction of 7.27 to 1. Which should be an equivalent increase in power. So the 3hp turns into ~21 hp.
The pump is rated at ~10gpm, but is limited by the valve body which is rated at 6gpm. It's a Williams Machine & tool pump, model 30.

I haven't had much time to worry to much about the engine. At some point, it could use a rebuild to freshen it. I have experience and education on engine rebuilding, so its just a matter of getting the time, and high enough on my priority list.

I haven't heard of Morey's before, so I did a quick search about it. Is it legit? Seems more like a snake oil than anything. Any first hand experience with it?

Thanks

I've been using it for about 40 years and swear by it. When I was doing gas conversions,(L.P.G & C.N.G.), I pulled down engines that had done extremely high mileage that had been on it since new and had no measurable wear. Works great in hydraulic systems too. An easy demonstration is add some of the oil stabiliser to a machine and measure before and after temperatures in operation. Nothing can fix a worn out engine but a rebuild but Morey's can get a lot more work out of it.
Someone mentioned it's now called Lucas, I don't know if this is true but Lucas and Morey's are both sold here.
