squonk 44,515 #1 Posted March 7, 2014 I have a chance to pick up a 416-8 from a guy I know well. He bought a 0-turn and his son was helping with the 416. Onan was running well but when the engine was shut off,oil started running out of the flywheel area.I don't think a front seal would give up like that but who knows. Tractor was babied all it's life and sounds like it's in decent shape. it's been parked a year and he wants rid of it. Any ideas? Share this post Link to post Share on other sites
cleat 7,641 #2 Posted March 7, 2014 You would have to take the cover off to see. Could be the oil filter, oil pump, oil pressure switch etc. lots of leak points in this area. Share this post Link to post Share on other sites
Kelly 1,033 #3 Posted March 7, 2014 I have never had a major leak on that side, PTO side yes, if the price is right buy it. Share this post Link to post Share on other sites
varosd 1,185 #4 Posted March 7, 2014 Mike, you havent picked it up yet!? I really like the power of the Onan with a 8 speed tranny. obviously not a 520-8 but close! Share this post Link to post Share on other sites

motox25 36 #9 Posted March 8, 2014 I got lucky with mine, replaced the engine oil filter and that fixed my problem. It wasn't making a good seal. There is also a gasket for the oil filter, but more likely the oil filter if it's leaking from that area. Pull the shroud off and that should give you a better idea of what's going on.

squonk 44,515 #11 Posted March 14, 2014 He still hasn't decided if he really want's it gone or not. Real busy guy works 50-60 hrs. every week. When spring hits and he's cleaning out the garage he may decide then. Share this post Link to post Share on other sites
