I use the PGlaves concoction of greases to lube my splines. I suspect he will be along soon to provide the formula.
Curious what dealership service departments use?
They probably use what BMW says to use. This has been a disaster in the past, but Oh Well.
BMW has over the years specified a number of substances for clutch hub spline lubrication. They have included copper based anti-seize which was totally unsuitable. Then they said to use a red grease which was actually Texaco Starplex. It was even more unsuitable than anti-seize. The BMW branded grease would actually melt and ooze sitting on a shelf, let alone in the hot environment inside a bell housing. Then they said use Stabarugs paste which was an assembly lube. One thing about assembly lubes is that they are very good for a short time, which is their purpose. So once again we saw premature spline wear and failures.
I neither know nor care what BMW says to use currently. Normally I am a purist as far as BMW specifications go but not in the case of spline lube. There was a reason that back in the '80s BMW said to lubricate clutch splines once a year and that reason was the use of an unsuitable lubricant. Maybe things are better now. Or maybe not.
So I ordered a Quart can of their TS-90 Moly Gear Concentrate and ask if this a direct application or something that needs to be mixed with another grease to make the final application sufficient? I've never greased a final drive spline before so this is new to me. I am riding a R nineT which I intend to make a permanent bike for my riding foreseeable future so want to make sure I do preventative maintenance.
Sine we also talked about gear oil additives...
Dow Corning M Gear Oil Additive was recommended by Oak some 30 years ago.
I've always used it at 5% on all of my single-sided final drives (R100GS, R1150GS) and they have been trouble-free since the early 90s with zilch on the drain plug between changes.
After a while it became hard to find...
I got my quart bottle at my local bearing shop.
I just got this from T.S. Moly-Lubricants because I wanted to know if the TS-90 Moly Gear Concentrate could be added to either mineral or synthetic gear oil.
