Speedometer lubrication

[Tim Larson]

I'm wondering what the best option is for lubrating a speedometer/speedometer cable. I tried searching the forums, but really couldn't find anything.

There should be an oil cap on the back of the speedo. A couple of drops of 3 in 1 oil. Remove the cable from the speedo and the trans. The inner cable pulls out of the housing. Clean and lube with graphite. Should be good to go.

There are a few oil caps to maintain on these old cars, most are awkward to get to. I use to always carry a zoom oil bottle with me when I had to maintain several swamp coolers.

They have the same oil cups.

You can also pull the worm and clean and relube it.  Messed job and could stain your rug and upholstery.  Disconnect the cable from the gauge. Reach into the cable with needle nose pliers.  Pull the square end of the inner workings out.  You might want to spread out some old sheets or towels to protect the area, as the worm is about 5 or six feet long and will be covered in grease.  

Once removed, clean with light solvent let dry then use graphite, or white lithium grease to re coat it as you slide it back in.  Reattach the cable to the speedo should be good to go.
