how big of a pump do I need to power my loader. The loader is a johnson 725,not much bigger than olcowhands. The loader came with the loader,cessna, but I cannot find any info on the pump...displacement, max rpm.

Almost any pump will run the engine's max rpm of 3,600. Mine is running at about 7gpm at full throttle, but has plenty flow even at slow engine speeds. Have a pic of your pump?

That would likely be an 8 to 10gpm pump at 3600rpm. I would start with a bit of reduction from engine speed. I'd say it would do fine. But, I'd put the pulley up as close to the pump body as possible. Having it out so far with the strain of a tensioned belt may likely cause a pump shaft/bearing failure.
