<VV> Speedo

Wed Nov 2 10:56:19 EDT 2011

 Probably the best lube for a speedo cable is some form of dry film lube, given how relatively slowly this thing turns. Graphite is great, so is dry moly lube or dry Teflon. The problem with most greases is they get really stiff at low temperatures, and this will hasten fatigue failure of the cable, especially given the tight bend is at the beginning of the cable, adding to the stress. 

Something like this might be fine, as bicyclists are looking to reduce drag on everything as much as possible!

Bill,

That is my experience as well. There is one hole in the speedo head. You
can turn it by fingers and get boththe speedo needle to move and the
odometer wheels to turn. Yes, it takes a lot of finger movement, but the
odo will change by a tenth of a mile.

I do disagree with the grease suggestion, but it works for you. I have used
the graphite lube sold for speedo cables when available. When not
available, I use ATF. Temps here range fron 0°F to 105°F during the year.
Most of these lubrications were when Corvairs were THE winter car to drive.
Had to keep the speedo from chattering/squeeling when the cable got cold.

Not normal, I resemble that remark!

WHAT??!!

Respectfully, I disagree.  Same cable, yes.  Different locations, no way,
not for common domestic speedos from the Corvair decade.

I could be wrong, but I have disassembled several Spyder and Corsa speedos
when they quit as well as others, and there is only one gear driven
directly by the speedometer cable and everything else runs off of that
driven gear.

I have greased speedo cables for a long time, and many of those cables have
been driven over to (or used in) the eastern side of the Oregon Cascade
mountain range in winter time, where temps often go below 0F and stay
there.  No problem, but that is just my experience. BMC, Corvairs (earlies,
lates, and FC's), VW's, Ford trucks, Chevy trucks, Isuzu trucks -- I'd
include the Fieros, but first I don't recommend it as a winter car (poor
headlight angle when snowing at night), and second, they don't have a
speedo cable.

Remember, grease doesn't freeze, it just gets thicker at normal domestic US
cold weather temps and speedo drive cables are fairly strong, even long
early Corvair ones -- arctic weather is where graphite is required. Maybe
folks that drive their Corvairs in 10W oil weather might want to consider
it -- Yoopers and folks from similar sun-belts.  These days, most normal
folks park their Vairs inside during that type of weather.  I know, Corvair
owners are not "normal".
