Hi,
Which type of lubricant & method of lubrication do you recomend for the speedo drive cable?

I would guess that running some regular engine 20W50 engine down there would do the trick. If the cable has had it, just replace it.

I seem to remember reading, years ago, that you should only lubricate the speedo cable with grease, never oil. Apparently, the spinning action of the inner can 'screw' the oil up into the speedo head and ruin it. Seems feasible.

I have had the advice that, it would be best to use something called Waterpumpgrease...directly translated from danish. It is some white, pretty hard stuff...like old hairwax. Very sticky and water resistant.

I stand corrected. I guess if you can pull the core out of the cable assembly you could apply grease. It would be difficult to force sticky grease down the cable otherwise.

I found an aerosol can of white lithium grease that is great for this purpose.

While putting a lot of oil in a cable might pump it, that won't damage the speedo. Depending on where the holes are, it might oil your crotch. :oops:

I used the same white lithium after cleaning up the hardened remains of the original grease inside the speedo, so pumping it in there might be considered a good thing.
