Very useful, thanks!In case you haven't done this, the specs attached below should help.
Not knowing the history of my bike, I didn't want to take the chance of the spline in the rear drive go bad. As mentioned above the rear drive is very expensive, I'm loving the bike. So, on one of those cold / rainy days I decided to take the plunge and removed the rear wheel. For this I was ready with moly grease in hand in case I needed it. When I removed the spline I found grease but it wasn't moly, it looked to me more like axle grease or disk brake grease, some kind of grease. I cleaned the spline and shaft really good with simple green making sure to wipe off all the grease and applied 60% moly to the spline and shaft. After that I was finally able to get a good night's sleep, Lol.

So, I was looking for this Moly 60 that has been very well covered in this thread and it seems it was discontinued. Is there any truth to that? It's all over the honda forums and within Google search to use M77. Is it fact or fiction? Is moly 60 still available?
Either one will work without any negative effects, 60% moly or more. I use the M77.
the Loctite LB 8012 is what I have been using on the splines, based on advice from others. But my bike has only 9500 miles and I used this about 2000 miles ago, at a rear tire change so I dont have a lot of history.
Would this workthe thing that worries me, the photo of the 75W bottle shows transmission gears, and it does not say "Hypoid" anywhere on the bottle
the 90° gears in the final drive and differentials are called hypoid gears. There are additives ( EP?) needed because of the way the beveled gears slide and mesh....
its $5 for another bottle of proper 80W90 hypoid gear oil.... its $500 if the 75W eats the gears in the final drive.
I would not be able to sleep at night... its the photo of the straight cut gears on the bottle that would keep me awake.
Many bikes will go 100k or more without somebody ever looking at the shaft drive splines. Same with cars. However, cleaning off the old grease and re-grease once in a while surely will only do good. I got my bike with 18 years 13k miles on it. The splines still had grease from the day it was built on all splines, but I naturally cleaned it and replaced it with fresh moly grease.
the copywrite of the clymers may be before the talk of moly begani recvd my clymer repair manual today. no where did it mention using moly to grease splines. ...it says use lithium grease also it did not even mention tearing down the final drive shaft and greasing all the splines i greased the other day using that ep moly3 ....it actually diesnt even mention m77 ...so im thinking lithium grease is fine. to use. and it did mention the hypoid 80wt gear oil i just wonder if greasing the final drive so aften why wouldnt it be listed in the general maintenance 🤔🤔🤔 View attachment 107175
If your shaft fails between tire changes, it is not because you used the wrong grease.
There are far bigger machines with far more torque and stresses on their splines that don't seem to have problems with regular grease. Think about all those tractors, cars, trucks, machinery, ECT. That do fine with regular grease.
This question is akin to "what is the best oil?" And it has the same answer, anything is better than nothing.
