I have a Case 580 backhoe that has pins on the bucket that move but have no way to grease. When dealing with the dealer, we could not find anything any different in the parts list. To me this is poor engineering. If a pin is not locked in place in its hole, it should be able to be greased. And I mean LOCKED in place. On our Gehl the Quick attach pins are greaseable in their bushings. and if you don't grease them they will bind, yet they don't spin, they just have a linear force placed on them with every push or back drag. They are proof that just because a pin doesn't turn in its hole, does not mean it does need grease. On our injection molding machines were I used to work, there were pins used like this. They had almost no force on them during the movement of the cylinder but held a large amount of pressure stationary on every cycle - sometimes cycling every 15 seconds 24 hours a day for weeks. They would were out if you did not grease them.
I'll get off my box for now.
You might consider have the pins drilled in such a way that you could grease the area that is wearing. I have actually done this with a half inch drill to make a hole in the center of the pin and using a v block from Horrible Freight, drill a cross hole. Drill and tap for a grease zerk.
