I seem to remember adding a fitting to the axle of my H14. What was an owner supposed to do? Use a pump oil can and squirt some oil up in there when you think of it? More likely they just didn’t get lubricated. I have replaced the pivot pins on most of my tube tractors. A couple of them with no way to grease them-were worn really bad. One tractor also had the holes in the support worn so badly that I bored them out and put bushings in it. The no grease fitting idea was a bad idea IMHO.
