Shell BT grease 3 for variator

Postby abobotek » Tue Jan 04, 2011 3:35 03

Does anyone know what type of grease should be used as a substitute for the no-longer-available 'Shell BT grease 3' that the service manual says to use in a few places on the transmission? My Internet searches haven't identified either the specs for this grease or any substitutes. Does anybody know what type of grease this is? Please refrain from any 'use a good grease and it should be OK' type comments unless you really know them to be true. There's usually a good reason for the service instructions calling out a special-purpose lubricant in a very limited number of places (such as in this case where transmission parts slide rather than spin against each other) in a vehicle.

My surmise is that this is a NLGI grade 3 (thick) grease to help the grease stay in place as the primary and secondary sheaves slide.

The variator also can run quite hot, so another question is whether or not a normal temp grease would be OK here. Most automotive greases do not last long at 300F, but there are special high-temp greases that will.

Several people have posted that some time after having transmission service (e.g., a belt change) they have had wear and/or found no lubricant remaining in the places where Shell BT grease 3 is called for.

That's a good question.

Have you called Yamaha Customer Service???? They should be able to tell you. I was put in touch with an "oil" specialist when I called about GL4 gear oil.

Called Yamaha CS this morning to ask. It took them most of the day to get back to me, but here it is.

The Shell BT 3 grease was replaced by:

Yamaha# ACC-POLYG-RS-10 grease. See the last link from a Yamaha dealer.

I was told it is a "NLGI #2 grade" grease, used to resist rust and oxidation, and is a high temperature and high speed lubericant.

Some links for more info:

http://en.wikipedia.org/wiki/NLGI_Grade

Look in the bottom LH side of the page:

Can get this at my local dealer:

Thanks for the great information! I have my first belt change coming up, and will to put the right grease in there. My surmise is that some people have put a normal temp (lithium or molybdenum) grease in there, and found that the grease is gone after some hundred or so hours of operation.

Thanks much for the research time you did to answer this question. I have tried to contact Yamaha service about this but was not able to get them to answer . Perhaps I had a wrong phone number. Now I can have some on hand for the next belt inspection.

I have some Honda Moly 60 left I may try when needed.

There is a different version of that Shell grease available: Shell Retinax LX2.

It appears to be a direct replacement for the BT Grease 3 specified in the shop manual.

Cheers!

The Shell Retinax is a lithium-based grease. I would be very leery of using that Honda moly grease in this application.

Ciao!

Shell BT Grease 3 (no longer made) is a Bentonite clay-based grease. It is non-melting and suitable for high temperatures.

The replacement recommended by Yamaha as a replacement for Shell BT Grease 3 (printed in their lubricant sales literature) is a polyurea grease. Polyurea greases are also suitable for use at higher temperatures (e.g., up to 500F dropping point) than the ~350F that most soap-based bearing greases top out at.

I wouldn't use any lithium or soap-based where the shop manual calls for Shell BT 3.
