I'm going to break down and get the 2 oz tube of Extreme Pressure for $38.00.

Altho my splines are in excellent condition at 32k miles, I do NOT want to have
to go in to disassembling the bike to this degree any more than absolutely necessary,
or to in any way encourage spline problems by using less than the best lube available.

macx, I know a veteran BMW mechanic of 23 years that swears by Lubriplate 3000. (SKU: L0108-098, Lubriplate 3000, NLGI No. 2)

He claims it out performs any high pressure grease he has seen and used in his entire career. I'm going to try it out this winter on all the splines, including the clutch splines.

It's worth look and the price is right!

I'm an old hot rodder and used to use Lubriplate (do I have to admit this? ) back in the mid 60's.

Been around a long time, very good product. I have to admit I don't know anything about the level of it's extreme pressure properties which I would think the more the better to have on those splines and would make an application last longer. Lubing them is not for the faint of heart or anyone in a hurry!

Back then, what I used to use during engine assembly was about the consistency of a very light grease, but there are obviously different variations and / or upgraded formulas.

Good luck!

I used the DuPont Krytox on the last spline lube. It will be interesting to see how well it held up when I do it again this winter.

Let us know, will you?????????
From all I've read, Moly is KING...when it comes to lubing our splines.
Krytox= 5% Moly max
Lubriplate= 3% Moly minimum (?)

We've all heard the HondaMoly--HondaMoly mantra....it's 60% Moly. Good stuff.....
This is what I use...

It's 65% Moly in a high quality carrier.
And you can get it here.......

macx, don't waste your money on Krytox, jm1515 is absolutely correct regarding the Moly content.

However don't be fooled thinking that the best grease in the world will correct issues with poor design/misalignment, just hope that you weren't blessed with one of the troublesome ones.

I read somewhere (possibly here) that BMW mechanics were stating that spline failure was primarily due to corrosion (rust). If that is true, and since everything I have read here and elsewhere seems to indicate the root cause of the failure mode remains elusive, then the main function of grease would be to shed water. In which case grease is grease. Is there any hard data backing up the moly content or is it just gut feel? Perhaps high-moly blends hold up better in the presence of water?

Are there any riders who post here who experienced early spline failure, repaired the problem, religiously lubricated the splines, and experienced no recurrence? Or the converse: those who despite lubricating a repaired input shaft experienced failure again?

I also wonder if those experiencing input shaft failure ride more in the rain? Or wash their bikes more often? Or use pressure washers? Or ride in rain and then let the bike sit for a week? Have these questions been addressed as regards spline lubrication and spline failure?

Incidentally, the active ingredient in moly grease is molybdenum disulfide which has the property that it forms a strong film on metallic surfaces. In situations where the petroleum based components fail - as in being scraped away - the MoS2 prevents direct contact of the lubricated parts. I just wonder what kind of properties this thin film has and if it holds up in the presence of high shear as would be experienced in a floating joint such as this or if it is better suited to the compressive forces seen by ball-bearing type rotating mechanisms. Be a good science project for a gear-headed high-school kid.

A lot has been written on the subject, see attached link

I read this info which I believe was posted in a link that was included in one of the spline lube threads on this forum at some point.

I've already got some coming and also have a tube of the Honda Moly 60. Maybe I'll coat one half of the trans input shaft with each one and see what it looks like next time I have it apart.

"An alternative to moly is the new poly-flourinated lubricants made by DuPont called Krytox Teflon Bearing Grease. These chemicals are simply magic. They have almost no known solvents, are chemically inert, and don't burn at any temperature, even in a pure oxygen atmosphere. This is pretty clearly the only grease to use. See this article. Nascar mechanics have found that Krytox grease can reduce the temperature of spline joints on drive shafts by 150°. Also, this stuff lasts forever. It is, unfortunately, quite expensive. "

I seem to recall this stuff being used to lube space shuttle main engine TVC bearings. Another crossover technology?

TUNGSTEN, lower coefficient of friction than molybdenum

Anyone have a long term report on how well the Loctite moly paste works, I bought some about a year ago, but still haven't tried it.
