I don’t know of this helps Ted but I bought anew grease nipple for my 550 K2 from Julie, screwed it into the swinging arm using the original thread and used my new bought from Halfords grease gun. All seemed to fit and work ok
Ted, if you push the gun tight into the nipple whilst pumping it you should eventualy see grease appear from the ends of the swingarm mate
