I’m just a do it myselfer no means a mechanic not a lot of help looking things up and the manual is terrible probably just take it in don’t have time to keep pissing with it endless possibilitiesThat makes it easy. With the tractor off disconnect the loader inlet hose and stick it in a clean 5 gallon bucket. Set throttle to minimum and start the tractor. You should get a solid stream of oil from the disconnected hose. Turn the tractor off as soon as you get flow - you can dump a lot of oil real fast if the pump is working.
