Check out Honda Moly 60, that might be close. It's a 60% moly paste that is very good for high strain gears as the moly is absorbed by the metal and still protects when the paste is flunk off. The regular moly paste in most auto places is like 3-5% moly only.

thanks for the reply. But I would prefer something available on amazon.. free shipping is nice to lol.
I'm guessing this is very similar?
http://www.amazon.com/Yamalube-Molyb...6106794&sr=8-1
I can't justify paying $7 to ship something that costs $7..

Check your local auto parts store. Moly EP grease is not hard to find.

would napa or autozne have high quality, high percentage grease? like a high percentage of the actual stuff suspended in good grease? thanks for the suggestions online but I don't want to pay the shipping fees for a small purchase of grease.

The black grease for Ford Disc brakes has Moly...Thats why the grease is black. It's about $3.99 for a 1/2 qt sized tub.

Don't overthink this one, it's just regular moly grease from the auto parts store. Not a high pressure, high temp situation, damn near anything that won't drip out will work.

Recox, just out of curiosity, what do you do for a living?

Funny, I just made some moly grease the other day.
I was working on a spring powered airgun, and it required a special moly paste (regular grease has oils that can diesel combust in the piston causing damage).
I just squeezed a little silicone grease into a dish, dumped a spoonful of molybdenum disulfide powder into it, and mixed it all up. Had to have been about 80% moly when I got done.
It started out super tacky (as the high vacuum silicone grease is tar like thick), and just got more and more slippery as I mixed it between my fingers.

Years ago, right after Molycorp reopened their mine out west, 1lb packages of moly powder were on eBay for really reasonable prices. I watched about 20 auctions get bid past what I was willing to spend, before I won one at around $25.
Nowadays its more like that for a couple of ounces, but the stuff is really handy to have around, and goes a very long way. An ounce is plenty to do a whole lot of things with.

I've also suspended it in naphtha to dry lubricate camera shutters, and other sensitive parts which must be completely dry.

Here's another source:
http://www.midwayusa.com/product/183...ly-powder-6-oz

Moly is a fantastic lubricant on steel against steel sliding surfaces. Offhand, I can't think of something that prevents steel on steel wear better (although the graphite contaminant that is often in it does cause wear) and it works in a wider thermal envelope than any grease. Not necessarily so great on other setups though, as it doesn't plate itself so well to yellow metals.

But, all that aside, the manual specified by the OP is almost certainly referring to moly fortified chassis grease. The black stuff. This really isn't something special, and can be found at just about any auto supplier.

Edit: Oh, and if you're really nuts, tungsten disulfide is actually a better lubricant, and as moly's price has risen so much, if you're going to buy one or the other, the tungsten might be the better choice.

I still want to use the correct grease. The books specifies it for a reason and I've read horror stories about lithium and silicon grease getting stiff and gummy. I think lithium is bad for the bushings too.

Yes they would, But I was their yesterday looking for a bunch of parts and the wanted insane prices.. example $93.13 per quart of gear oil. $7.98 for the DRL bulbs ( find them online for .80 each, made in Germany). $58.91 for a thermostat.. Got one made by the same company in Germany for $18. aftermarket ones available for $10.
..they would probably want $30 a gram for the grease.

No probably not. I have a few different moly greases, just none specify what percent they are.

probably a low percentage at that price.

Look for the Moly EP grease that meets the Ford Spec. It came out in the 60's and absoutely will stop wear on poorly lubed parts.

Thanks for the shooting supply link for MdS. I will probably run down to the Bullet Hole and pick some up. I have been mixing graphite into lithium grease for years for a special lubricant. The high vacuum silicone grease may be harder to find locally but I have a few places to look.

thanks for posting the MSDS.. I'm not interested in it but maybe someone else is. and I picked up some ford spec moly grease made by valvoline... It doesn't even say it has molly in it though.. Or what percentage. I don't remember exactly what it says. I might just end up using the Honda M-77 mos2 paste I have. does anyone know what percentage that is? It is black grease but has lots of silver particles in it so I'm guessing its a high percentage.

The silver particles may be graphite. Google the ford spec number and see what you can find.

I used my graphite mix on my old VW bug shifter.

since that moly bearing grease can last 50,000 miles in a wheelbearing spinning millions of times a day I'm sure That your shifter application will be a walk in The park for it.
