M77 Replaces Moly 60- Apparently So

[Larry Fine]

There is a better Loctite product that is sold only in Europe.

It sounds like I'm right to be cautious about Motorrad's recommendation of Klubergrease LFT 71-402 with no moly and developed by Kluber for lubing sealed for life ball-joints.

I don't have any BMW so the below is based on what I think is the case with them.

Doesn't your BMW have a single sided swing-arm? Doesn't the wheel bolt on to the final drive much like a car wheel does?
There are no splines in the BMW wheel that mate with splines in the final drive like there is with the ST1300. The mating surfaces of the ST1300 final drive splines and the driven splines in the rear wheel is where the 60% Moly paste is called for on the ST1300. What I think that you are describing is the sliding mating surfaces of the splines on the two ends of the drive-shaft, which has nothing to do with the final drive. These splines on the BMW drive-shaft are not equivalent to the final drive and driven splines of the ST1300.

The splines of the ST1300 drive-shaft that mate with the transmission output shaft are equivalent to what I think that you are talking about with your BMW drive-shaft splines. On the ST1300 drive-shaft the splines are lubricated with Moly grease, not Moly paste, in accordance with Honda's instructions. If I remember correctly this Moly grease has a very low Moly content, something like 3%. I think that the two applications and requirements are being confused and this is what accounts for the difference in Moly content requirements.

The rear splines on the ST’s use paste in a dry area for the impact protection, as stated, the front input splines on the shaft use grease because they live in an area with gear oil, and paste does not play well with other lubricants.

Did you clean the splines completely, and check for wear on the splines? Or are you just saying that the paste still appears to be on the splines?
You may want to inspect them a little closer. I have found many damaged splines since Honda started using this product.

I watched the guy clean it up then put the moly 77 on. But I did not see him inspect the splines. Time will tell as I only have 6K miles on moly 77.

And while my screen is small, for giggles look down under the section "Parts Information", where it seems I read... "Cheese Head Screws"? Too funny.
Maybe I misread it.

You did not.

What are cheese head screws?

Written by Jody Muelaner "Cheese head" screws are defined by their head type. The cheese head has cylindrical sides with a flat disc top and a flat

Hmmm.
That is not what I've come to experience as "cheese head" hardware or fasteners... I've always seen it as a derogatory reference to soft metal that easily deforms under persuasion of screwing hammers, left handed monkey wrenches, or other tools associated with dismantling machinery and such.
Not too old to learn new things.

These had one third of that mileage, after the dealer replaced a damaged spline plate and used the M77 to assemble everything.
Just saying

praying it doesn't happen to me. now that the top Kawasaki and Yamaha sport touring bikes aren't being made anymore I have more incentive to keep this one on the road.

Just posted some genuine Honda moly 60 for sale in the for sale section if anyone is interested.

Just for info to newcomers to the thread. No one has ever been able to show me a document that says that M77 is the replacement from M60 - for use on the final drive splines. I have seen a document for certain cars (Civic, Accord I think - but don't quote me), where M60 was being used on the back of brake pads, and that M77 should be used instead.

If in doubt, the Rocol ASP - now Dry Moly Paste - is one of the other Honda recommendations listed in the shop manual, and it is still readily available. It is what I have been using to good effect for the last umpteen years.

 

[Igofar]

I agree with John on this.
The M77 was an assembly grease, to be used on the back of brake pads, not splines.
Here is Honda’s statement: TO BE USED WHERE GREASE IS CALLED FOR.
The service manual calls for paste on the splines, not grease.

 

[Sadlsor]

Would it be safe to say at this point, if we find / have some percentage of moly in a paste form, that the real takeaway is to clean and inspect the condition of the splines at regular intervals?
Meaning, at least once a year if you aren't riding enough miles for a tire change, as in roughly every 6000 miles, is what I have in mind. I actually am using about an 8oz tub of mil-spec moly paste which I got 20 years ago.

I had planned to moly-kote my rifle bullets (I roll my own) for matches at the range and general practice, but quickly found it was way too messy so went to Hornady's factory moly coated projectiles.

So I don't know the actual percentage of molybdenum content, but I do routinely clean the rear end, and reapply a not-too-thick smear, and my machined pieces are still looking good on my less-than-30k miles ST1300.
