Speedo cable lube????

[KBMWRS]

So as Kelly can attest to my speedo was a little off. For a year now I've been driving with it bouncing around about 5mph...then it got worse. Last year on the way to Knotts it read zero then back to speed. Last week at 40mph it was reading 80 then 90 then 100 and the next look I could not see the needle anywhere.

So I bought a new speed cable and today took the old one off. Mmmmm, the old cable is in one piece (I slid it out). Turns/rotates OK. I check the speedo gear...yep the inside where the square cable pushes into must be rounded...no good. Ordered up a new one. Just need to wait to get it from NPD.

Now for install....I'll cover the cable just to protect it from the 390 heat but should I also lube it before install?

what type of lube? white grease? Graphite oil?

Mike, always lube your cable before insertion.

That's what she said.

There used to be a product specifically for cable lubing, but I haven't seen it since I worked at Napa ages ago.

Yeah I found ONE last tube of that cable lube at a NAPA.

Graphite dust - used for decades on pinewood derby cars

That's what this cable lube is. Graphite in a oily liquid that evaporates. It gets it down the cable and then its coated with the graphite.

Then you are good to go!
