I think I remember seeing a post or thread from someone recently that is compiling data about Yanmar tractor hydraulic pump specifications . I have a 186d and today I remembered to look at the data plate on the back of the pump for the specs . Here they are . Pump # GP1-C-7C , pressure 140kg/cm , volume 7cc/rev. Hope that helps .
Hi Mike, that was me, as Winston said. Thanks for the information. Your machine agrees with mine, and what the brochure says, too. If you want to check on your Buck, I can start a list of Mitsubishi machines, too, or any others you have.
