John Deere cornhead grease comes in a standard grease gun cartridge. It something like halfway between grease gun grease and 90w oil. It is a flowable, non channeling grease. The next “wetter”, but not quite oil is cotton picker spindle grease. I don’t know Sae or technical specs. The transmission, chain drive, and differential are permanently lubed, but adding a little wouldn’t hurt.
Is this what it looks like? I pulled the Neutral switch and stuck a piece of wire down in there and this was on it when I pulled it out.
I've been busy this morning. Wire brushed the battery box and got a coat of Rust Reformer on it.
The screen over the flywheel was not stock and had too big of holes for me. The fins under the cylinder were full of crap and the only way to get the underside one off is to pull the engine. So I made a new screen.
Then I went to work on the head. Wire brushed it first.
Got out the glass and some 400 grit sandpaper. Tape was to hold it there for the pic.
Worked it some and found the high points. With a straight edge, I saw this would take a lloonngg while with just sandpaper, so I got out my air die-grinder and a brown scotch-brite pad. Used it to 'ease' off the excess in the high spots (did this a lot in aircraft).
After a lot more motion on the sandpaper, I think this will work fine.
