Ok.. It was spinning the wrong direction.. It was working, but it sounds better now.. It does not seem to have hurt anything.. I was looking for an arrow on the pulley, but nothing.. Seems like they would have done that..
I have a guy telling me that the little air line going to that crank cover is disengaging the compressor mechanically until the motor gets up to speed.. I might just open it and see what the deal is for myself..
So do you just run normal compressor oil in these big ones? Or could I use some type of motor oil?
Sure could have used a owners manual with this one.
