62 Valiant Speedometer

Before jumping on the rebuild expense. Remove your speedo and clean the 40 years of dried up gunk from it. Lubricate it with 3 in 1 oil at the input and center bearing. Do not over lube it. Turn the input buy hand in the direction of increasing speed until it spins freely. Pull the cable out of the casing and inspect it. If the cable looks good, I use a liberal amount of lubriplate on it and reinstall it. If it is damaged you can buy a universal speedometer cable from most auto stores for around 14 dollars. Inspect the cable casing for damage to as a kink or burned jacket can foul the cable with dirt. If that is damage you will have to find a used one because no one that I know of makes the one piece as a repro.
