Using a "Dry Lubricant" in the J. Costa

Hi,

I'm thinking of using a 'dry lubricant' inside of the bell housing when I replace my pins. I was reading on another site where some people were using this in the tracks for the rollers, in their stock variator, and it quieted and smoothed out their variator and ride. So I'm wondering if anyone has every done this or thought of this.

I got the idea a few days after watching the video of how the J. Costa works. It seems it would reduce the friction and heat when the pins push against the housing. Since it is a dry lubricant it wouldn't get it messy everywhere and it seems to work great for the stock variators.

So, I'm going to try this but was wanting to know if anyone else heard about this. It seems, since it would reduce the friction, that it may also lower the rpms a little, and maybe improve the mileage. But this is just me thinking about this. I just know that when you reduce friction it seems everything else is happier. What do you think?

Here is the video on how it works. You will see how the pins push the housing out.

Does the dry lubricant really help on a stock variator?? Hadn't read about that trick before.

Jeff,
I can see how the dry lubricant would make it more "happy" and "efficient" and even "smoother" but I just can't see how the rpm's would drop? You may not need to punch it up as high so you could keep the rpm's lower but the physic's wouldn't change just because roller's were "smoother?"
I'd love to see the other discussions. Are they using the teflon dry lubricant or the 3M dry silicon?

DickO & Dennis,

Here is the link about using the dry lubricant in the ramps for the rollers. Daboo was doing this while using the Dr Pulleys sliders but I would think it would work with others too. Read it over and see what you think please.

Just go down about 5 posts or so and look for a post by Daboo. He has a couple of them. The last one lists the type of dry lubricant he used.

Thanks JeffR,
But I think I'll leave well-enough alone until I "have" to get in that area for maintenance some day in the future.

Since the "gear ratio" is dependent on parts sliding past each other it stands to reason that less friction in the mechanism would result in different RPMs.

Other dry lubes:

Dow Corning "321": Molybdenum disulphide and graphite.

Sherline dri-film lube: http://www.sherline.com/7550pg.htm PTFE ("teflon") based. Personally, I'm leery of anything containing PTFE that is not licensed to use the "Teflon" brand name, but who knows?

Looks like you're going to find MoS2, graphite, PTFE or some combination of 2 or 3 of those. MoS2 is great. It's a standard anti-wear ingredient in high quality motor oils and gear oils, such as the Lubro-Moly products that Mercedes diesel owners swear by. However, given the type of materials and the sort of "contact" we're talking about a PTFE product (which is useless in motor oils) might actually be right up our alley.

Damn. This is the sort of thing that drove me to obsessive-compulsive distraction when I owned my VW diesel. Must....resist....urge to experiment!
