Ok guy's, did the first grease and oil on my SH. Found 13 zerks including the one on the fan hub. So how many did I miss? I can take it.... Oil was pretty dirty but not horrible. Found just a little sludge in the drain plug cavity so I won't pull the pan like I intended on doing if it was heavy. By the way, what is that little float type deal you can feel inside the pan through the drain hole? Moves up and down freely. Oil pressure went from 54# to a steady 60# with the fresh oil and filter. Cleaned out the air cleaner basin and put fresh oil in there too. Put a few drops of oil in the oil cup on the rear of the generator as well. The leak I posted about last night on the rear section of the tractor was coming mainly from the drain plug. Pulled it, wire wheeled it, teflon taped it and back together. Looks good. The 2 seals in the cavity just above the drain are showing some slight leakage but won't tackle that one yet. Anti-freeze is deep lime green and looks clean. No leaks on anything else so I think I'm good to go for awhile. Thanks for all the input!
