The little metal clip that holds the speedometer gear on the output shaft keeps falling off in my M20. It's not a lot of fun to put back on so I'm wondering if someone has been here before. It seems fine when I install it, but it comes off in a few miles. Maybe the cable is too hard to turn? My cordless drill spins it easily,. It looks like someone greased it at one point though. Both gears look fine and are a matched set. Any ideas? Maybe I should just replace everything (gears, cable, clip).
