The speedometer cable end had broken on my '59 38, so I replaced the cable and now I have a working (sort of) speedometer. For the first few minutes during my initial road test it indicated 100 mph even though I was only going 35. After a while it loosened up and now the indicated speed is generally correct. However, occasionally it goes very high, and then wavers, and finally settles back to the correct speed. Can the speedometer be serviced/lubricated? Or must it be replaced? All suggestions are appreciated since my only experience dealing with speedometers is replacing cables.
On the positive side, I think I set a new worlds record: 100 mph in a flat bed truck running a 235 stovebolt with 5.17 gears!
