Spline grease

[cogsman]

Hi all,

I'm just about to go and pick up some grease because I'm doing a rear end service. I'm going to be pulling the final drive, and I'm going to be checking the splines and lubing them up. I am noticing many threads on this site regarding the use of moly grease. To be honest it's all very confusing. If one of my Canadian friends can help, let's keep it simple: let's say I'm going to Canadian Tire... What grease should I buy and what am I looking for on the label? One thing that seems pretty apparent is that I should not be using any of the Honda moly 60. Any advice would be appreciated

Actually the Honda moly 60 is what the service manual recommends for the final drive cogsman, and moly grease for the pinion cup and driveline. You want a high content moly product (although some do not use it) for the ultimate protection of those splines. You can download a copy of the service manual if you don't have one from the Valkyrie Norway  site, and read what Honda and the engineers that built the bike recommend.

If your choices are limited at Canadian Tire, tell them you want a high content moly grease,and apply it liberally. No one will ever be as meticulous doing your work as you will, good choice on doing it yourself. When you do the pinion cup and drive line, CLEAN  those parts up good before re lubing to remove any abrasive debris. I use the Honda moly 60 because I still have a supply, but it has been superseded by a product called M77, it is still Honda moly paste.

Go to Acklands Grainger and get Loctite Moly Paste for the wheel to gear box splines.  You won't find anything similar at Canadian Tire.

For the drive shaft to pinion cup joint, find 3% moly grease.  It MUST say 3% on it.  If it just says moly, it will likely be closer to 1%.  Again, you can't get 3% at Canadian Tire.  Try a commercial supplier for this.  I got one tube from a specialty shop years ago, and it should last my lifetime.

The drive shaft to u-joint splines will be fine with any chassis or wheel bearing grease.

Pancho and Gryphon thanks! very helpful

This is my 3% moly grease:

Could you not just put Moly 3% on everything? And is it available at any local nationwide stores?

[98valk]

from tech manual content symbols pg .

Use molybdenum disulfide grease (containing more than 3% molybdenum disulfide, NLGI #2 or equivalent

Use molybdenum disulfide paste (containing more than 40% molybdenum disulfide, GI #2 or
equivalent).
Example: molykote G-n Paste manufactured by Dow Corntng, U .5 .A.
Honda Moly 60 (U S.A. only)
Rocol ASP manufactured by Rocol Limited, Uk.
Rocol Paste manufactured by Sumico Lubricant, Japan

Some people put no-moly blue belray waterproof grease on everything
in there, and have perfect parts with over 100,000 miles to show for it.
It should be easy to get at motorcycle stores.

I've taken to putting belray everywhere except where the flange goes
into the final, I still put moly paste there. Molybdenum (MoS2 really)
is a dry lubricant, that people observe that it "drys out" doesn't indicate
failure:

Molybdenum disulfide (MoS2) is used as a solid lubricant and a high-pressure
high-temperature (HPHT) antiwear agent. It forms strong films on metallic
surfaces and is a common additive to HPHT greases — in the event of a
catastrophic grease failure, a thin layer of molybdenum prevents contact of
the lubricated parts.

Grease (paste, whatever) seems to sling out from our flanges, good O-rings
or not, and it makes me feel good to still have the moly coating in there. It
also makes me want to look in there often enough to make sure there's
still grease (paste, whatever) still in there...

the moly is meant to coat and harden on the surface.  It is good to "paint" on a thin coat to all surfaces and let it dry.  The add more prior to installation.  Moly is indeed a dry graphite lubricant.  The grase or paste is just a carrier

graphite and moly are two separate materials. sometimes they are used in the same formula.
moly actually plates the metal and becomes part of it. it does not harden.

I use Lucas marine grease and honda moly 60 mixed together. About 80% marine grease and 20% moly. It is always sloppy wet in there every year I pull it to redo. I figure marine grease is good enough for boat motor lower ends that are always in water, it is good enough for splines.

   and you can buy both on eBay

Search "moly paste" at Amazon... there's a ton of different brands of
easily available moly paste, I got a little tub of some-kind-or-other
from there that lasted for about two tire changes once... the loctite
kind they sell at Grangers and Honda M-77 are the first two hits,
but there's a bunch of different brands...
