    Does anyone have a reliable dealer for parts for theses machines? They are over 20 years old and noone seems to have anything for them. I can find some engine parts through dealers but the rest seem like they are made of unobtanium.

    Swing motor oil

    Hey there, I'm working on a yanmar vio 20 and got a new swing motor. My question is do I need to fill it with oil, or is it lubricated by the oil flowing through it? There is no dipstick and only a couple small plugs on the side.
