Motor Mica ???

[George Andreasen]

I've known about "Motor Mica" for years as I use it in my cartridge reloading hobby.........but never knew exactly HOW it was used in a "motor". Today I stumbled across an old can on Ebay and the label caught my eye.

"Excellent for Ford transmission bands. Add proportional amount to oil (whatever that means). For best results pour directly over bands after changing old oil".

Now, I'm paraphrasing a bit but those were the instructions. So, this stuff was marketed as a band lubricant for the model T, but did it actually work and improve the transmission performance? Has anyone had any experience with it? Note: Motor Mica is NOT graphite, which would short out the magneto.

This accessory came to mind. Only way I can see it would get directed exactly where it was wanted.

So that thing distributes GREASE to the bands?? Nice.......would turn your 30 wt to 40 wt in no time. Reminds me of a solution in search of a problem....

Motor Mica is a very fine mica powder and very slick, just like graphite, but doesn't conduct electricity. However, I would imagine too much of it would coat the entire inside of the engine and maybe "sludge up" the oil. In effect you're just "adding an additive" to the oil that it didn't have originally.

Motor Mica is sometimes refered to as White Graphite. It has the same molecular structure as graphite, but isn't graphite; it is hexagonal boron nitride, a high temperature lubricant.

Of course, I do not know what is actually in the can that is for sale, nor would I know what a "proportional amount" would be. However, if I owned the stuff, I'd take every opportunity to leave it in the can.

For fun, I did a quick search for this stuff as it applies to old cars and found this: https://books.google.com/books?id=1K2Ep ... ne&f=false
