Reply to "Replacement speedometer lubrication"

George PAdmin.

The bouncing of the needle is probably caused by the oem grease, which gets very gummy with age. A spritz with WD40 down both ends of the speedo cable may dissolve the gum enough to smooth the needle out again. The purpose of the WD40 is not to lubricate the cable, just to replace the solvents which have long evaporated from the original grease, allowing the original grease to do its job again.

If that doesn't work or if you want to perform a more thorough repair, pull the cable, clean the old grease off of it, and relube with a light grease as Marlin suggests. I used the red general purpose synthetic grease I keep in my grease gun, I think its made by Mobil One. The important part is to select a light grease that will not thicken in cold temperatures.

x2 - Graphite is not for speedo cables.
