Would you please help me with any tips for reassembling a speedometer/odometer/tripmeter? I've put a light amount of 3-in-1 oil on all of the gears and shafts. I'll check gaskets/seals on re-assembly, to keep water out. The odometer on mine has been stuck since I bought it about 5 weeks ago. I suspect the corrosion on the odometer shaft, which you can see right above the trip-meter shaft. There was a spare on ebay, so I bought it, thinking I could assemble one working unit from the two.
