I finally bought a YM186D with power steering and a loader. It needs some minor tinkering to put it in service.
There is a tiny round bleed hole on top of the power steering hydraulic cylinder unit. This hole is at the front end of the tiny secondary cylinder that controls and sends fluid to the steering cylinder when the steering wheel is turned. It squirts if I turn and haven't turned for a while. My first guess is it should be an air vent and this is hydraulic fluid that got past the control cylinder's piston ring.
Has anyone seen, and fixed, this issue?
Also - this has a Yanmar YFL 650 quick-detach loader. About the same thing as a modern Koyker. All four quick-disconnects, and all the hoses, are covered with oil. I can't tell yet if I see years of never-cleaned oil on the hoses or actual dribbles. Anyone fixed that, too? I expect I will have to get four new hoses made.
Edited - better description that the vent on the little control cylinder leaks; it's not the main steering hydraulic cylinder that leaks.
