My mid 80s 2j has a set screw in place of where the zerk fitting is on this older (picture below)
The head placard says lubricated for life do not grease instead of providing info on what grease to use.

Responding to Marty, unfortunately my head has no oil cups or other ports into the bull gear housing¡the two cups I have are below that level, as is the grease port on the left side. All are two low to lubricant these gears. I suppose the few drops that get applied to the drawbar could make there way to these gears, but that seems like a stretch to me.
So my question to Nick is, is there a grease fitting on your head that would allow periodic greasing of these gears¡or were they still greasy in isolation after all these years?
