While late model Troop Carriers might have electronic, earlier ones were mechanical.
Grease or oil in the speedo usually comes from a worn seal on the gearbox speedo drive gear. There is no seal on the speedo itself. Graphite powder is good to lube a cable and in fact we used to actually add a little grease to the lower third of the cable when we made a new complete inner and outer cable.
However, no grease is better than too much grease. I found that if you tell a person to lightly lube their speedo calbe.. then they used to over dose the system.
In fact one fitter and turner proudly shwed me a grease nipple he had fitted via an attachment to his speedo cable. He then connected his grease gun and kept pumping until he could see grease through his odometer window on the speedo dial.
While I have seen oil damage in a lot of japanse speeds.. Holdens were the worst offender, or at least we saw more of them than any other makes..
So in sumary, graphite is good in SMALL DOSES on the bottome third of the cable. Some of it will work its way up to the top.
Hope tis helps.
Cheers
