The tilt cylinder pin should have seals either side to keep junk out too, the grease should hold in there pretty well.
LOL Bobcat_Ron, i knew you would see that
If its still under warranty talk to the dealer, it does sound like a fault to me.
When i did my 743 up, i machined out ALL pivot points so i could make bushings to suit. Every point now has a renewable bushing installed. Not that i will ever give it enough use to wear them out but i know if something was to happen i can throw a new pin and bushing at it and its back to how it should be. Its just poor design not having bushings, but i guess its good for the parts section. Its worn, just buy a new one, its only $2000.
