While taking the Simplex on it's first voyage in 20 years. The speedometer was squealing and jumping around (the needle that is). That's a classic sign of dried out lubricant on the drive bushing. By the looks of it, the unit has been apart before, or someone tried to take it apart. I've been hesitant to mess with it until I had a plan together. I unscrewed the drive cable while I was cruising down the road before it froze up (have had this happen in Studebakers in the past & just as they are trying to freeze up, they will snap off the small drive pin that the needle attaches to).
Anyone have any luck tinkering with these? I'm sure it was made by some speedo company who sold them to anyone & would put any brand name on them. Or, is there any services out there with good reputations on repairing them?
