Our very good Ac720 has an inoperative hour meter; are they reparable or where can I find a replacement? Herb(GA)

Mine doesn't work either. - been stuck at 1200 hours since I bought it over 10 years ago. I don't think many of them actually do! A lot of the Gleaner combines from the 70s and early 80s used the same type of hour meter. However, they suffered the same premature failures.

Pretty sure the one on my 720 has read 457.something since I've owned it. If I put a lot of hours on it I would change it. Since I don't.......
