Yamaha factory rep finally called

[ediddy]

I just got off the phone with the factory rep. He is at Tallahassee Power Sports and just finished riding my bike. He hasn't gone into the rear diff yet but believe's the problem is dry splines. He said in the past tires lasted approx 7,000 miles and yamaha recommended greasing the splines each time the rear tire was changed. The dealers also used regular grease on the splines and this solved the problem. Today tires are lasting 12,000 or more miles and with dealers using regular grease it is not getting the job done. Also there were some problems with some rear ends going out because the shims in the ring gear were too tight. After receiving notices from the factory reps in the field about this yamaha supposedly corrected this problem. This rep recommends that the dealers now use a moly 60 lithium grease. He said he uses it the field and at home for his personal use. He likes the honda brand moly 60 grease. Tallahassee Power Sports just purchased the honda dealership in Tallahassee so he asked the service manager to go over to the honda dealership and get two tubes of honda grease. The factory rep is going to re grease the splines and check to see if there is any damage to the rear diff. He also said yamaha will be notifying the dealers to start using the moly 60 grease. I hope this is the problem.

A good article on the Moly 60 grease is HERE

 

 

It also talks about Krytox, but the price of that stuff!!!!!!!!!!!!!!!!!!$30 for a 2 Oz tube!!!!

 

 

Wikipedia has a good article on Molybdenum disulphide

 

If you choose to use this grease at home, be sure to wear disposialble gloves, or you will be scrubbing for hours!!!!!!!

I agree with him. The Honda Moly grease has been recommended many times here and greasing the splines with every tire change is just routine maintenance. Unless there is indeed some damage, your problem will likely be solved.

Not to hijack the thread, but I am putting new tires on in the next week or 2. I was going to use the high temp, red lithium wheel bearing grease I have. Is that going to be sufficient?

[KiteSquid]

Sufficient? Yes.

 

Best? No.

 

Are there no Honda bike dealers near you? A Honda car dealer might have it too, but I doubt it.

Yesterday the factory rep inspected the rear diff and said there was no sign of damage. He greased the splines with the Hondal moly 60 and everything is fine. Thanks KiteSquid for the article on moly grease. That was very informative. I don't understand why yamaha doesn't get this info out to the dealers. When you talk to a factory rep you find out about all kinds of info they know but they keep it to themselves. I just don't understand.

Maybe they spread the Words, but nobody reads the Info's ?

I was curious so I did some reasearch and thouguth I should share what I found.

 

 

We used a high moly content grease (I don't know the %) on the moving parts of an antenna for a RADAR I worked on while in the US Navy and it was wonderful!!!!!! but it sure made a mess, if you got it where you did not want it... like on haze grey paint. A shipmate of mine got it everywhere and we had to repaint the antenna to cover it up as it leached into the paint within a few minutes!!! Dry-cleaning solvent took off the grease base, but it would not remove the "Moly-B-Denim" from the paint!!!!!!!!! We wanted to kill him for the work he caused us.

 

I will purchase a tube of Moly 60 ASAP!!!!!!

I am glad you got a resolution to this issue, even though you haven't put it through its paces yet to see how long it lasts (next tire change I guess).
