My JD X485 hour meter wrapped out at 1966 hours. Yesterday my new hour meter arrived from RS America. Mind you that this hour meter is internal to the dash that costs over $700 used. It was a pretty easy swap out soldering in the new hour meter. It was a tight fit getting the dash out and back in. The operation was a success and it works. I only had to unsolder and solder up four pins. I just looked up a new dash panel. JD wants over $1600.00 for a new one. The new oem clock was around $40.
