Spline grease

On my LM3 I was getting prepared to remove the drive shaft to see it's condition and found some spline grease in the garage that was lying around from my other bike.
Its Kluber Microlube GL 261 used for BMW splines.
There is talk about Wurth SIG 3000 grease that people use on there Guzzis.
Are they both compatible?

Well let me re-phrase ..... the GL has lithium ...... SIG has moly ..... will they both do the job?

What would you recommended?
Thanks
 
Anything that won't sling off is great. Guzzi doesn't even recommend lubing the splines. My personal favorite from working on BMWs is Amsoil synthetic grease. It sticks really well and lasts darn near forever. It is much better than the stuff BMW specifies in my opinion.
 
This is as subjective as an oil thread unfortunately.

I use a moly fortified grease. The splines will slowly push the grease out as the shaft length changes slightly due to the suspension alignment. That's why there are splines there. If there was no longitudinal movement then a taper and keyway could be used.

The spec sheet for moly grease states that it will still provide protection with a very thin layer if the grease is pushed out.

If you find a grease that stays in there then that is way better than no grease. Grease is a spline's friend. I don't think there is much difference between major brands. The type of grease and its properties is the important thing.

Most moly fortified greases are about 3%. Molybond makes a GA10 and GA50 grease which is 10% and 50% respectively. I also know that Penrite Cam assembly lube has moly but I don't have a ready supplier, have never used it and don't know its specs. Peter roper uses it.

If you want to get really paranoid about it then you can go for Tungsten Disulphide (WS2) fortified grease. Its supposed to be better than moly. Never tried it.
 
I wouldn't go to a point of not putting any grease on a spline.
Yet one member mentioned that when the bike was purchased new ..... Guzzi left it DRY.

The grease product that's on the bike now seems to be pretty thick ......given my garage is +/-10ºc. (That helps) :lol:
And like you guys mentioned ... I'll go with something thick enough that it doesn't sling all over like Petroleum Jelly

Thanks

Guzzi "left it" dry I believe is perhaps being overly kind to the Mandello guys. When seeing the ball of rust on the bone dry off-production line splines in my LM3, I rather think it has to do with something lacking in their procedures and quality control in the 1980'ies. I'll not start mentioning all the other interesting findings along the line of Mandello style quality control in a Guzzi of those days. I've read a few test drive articles in MC-magazines from that era and I recognize the pattern in what they complain about, the bikes simply weren't put together - just like mine! I suppose a good dealer can make up for plenty of factory mistakes, but perhaps not all of the dealers were up to it.
