Driveshaft Spline Lube

[sleeves]

While dropping my wheel off to get a new tyre rolled on this morning, I asked the shop where they get their molycote. They said "right next door". Lo and behold there's an old, old engineering supply shop with dirty old floors and a good old geezer running it. I ask, he goes to the clearance wooden crate and pulls out a 500gm container of high temp molykote. $9.95NZD thank you very much. I said "this will last a lifetime", He said "that's the problem with it and why its in there" Happy happy.

I had to get the Loctite from the US with help from a member on here which I was very great full for, I asked about the m77 assembly paste and a mate at Honda didnt recommend it for splines.
It is not the same as the moly 60, it has half the temp rating but most of all it was not recommend by Honda for use on splines, or though they will not tell you this officially as yet. I have known the mechanic there for years in fact decades and he use to own the dealership and race and was backed by Honda back in the day and he still has friends well up in the Honda chain and they are looking for an alternative to use on their bikes and brand it Honda of corse, because they recognise that the m77 will not be up to the job for use on splines but he said they won't say anything untill they do a deal and get it sorted out. He now use Loctite, which he have to get from the US and it's a pain in the arse for them to get. Apparently the bike shops have been on to Honda about it and have asked for a directive on what to use in the mean time for warranty work on splines for their bikes.
So @TOMCAT mate I wouldn't use it, I would get so Loctite from the US.

Bit late now mate, jobs done .. truth is the final drive really didn't need re-greasing. Only put a smear of the 77 on. Had memories of the first time I pulled the diff off and the dry powder-like residue I found. Pleased to find it wasn't like that.
Morgan tried to give me a Castrol grease to use , rang the Castrol info line and told it contained 10% Moly (at best) .. reckon the Honda 77 better option than that.

i don't know if that stuff is any good. got on their web site and couldn't find that product. I found the honda 60 on amazon about 3 months ago. It came out of California. One of the earlier poster had concerns about the splines that are in the tranny. the part of the driveshaft that comes out of the transmission. that is not a concern because there is no sliding on those splines. We are only concerned with the splines in the rearend because as the final drives moves up and down when riding ,that causes the splines on the rear part of the driveshaft to move in and out of the final drive. that can cause alot of heat build up due to friction if the splines are not lubed with moly. Moly is a dry powder that is carried by a base made of grease. the grease is only a carrier of the moly powder. The moly will actually molecularly bond to the metal
that it contacts and the grease carrier will disappear. the 60% concentration is very important. After 5 or 10 thousand miles after application of the 60% moly, one shouldn't find any grease left on the splines. the splines should look gray and dry. Always apply more moly when changing the rear tire.
Hope this helps.

The spline needs to be relubed way before it drys out or you will be buying a new driveshaft and diff.
More than one have been there done that.
Use the best stuff you can get and lube it at least once a year.

Quoted $5,000AUD for a new diff. Thankfully Triumph Australia came to the party. Got a spare diff and driveshaft squired away now.

I have got a new driveshaft put away and a diff with only 1800 klm on it so I should be right. and I have a few tubes of Honda moly 60 as well.

Here is a link that is very informative on the topic: Motorcycle Shaft Drive Grease

I use the Loctite brand: Google

I run a motorcycle tire on the rear in which doesn't last as long as a car tire so if I clean and lube the splines on every tire change then I will never have any problems. The main thing I believe is to keep the splines clean and lubed in a periodic fashion instead of total neglect.

I used my Honda Moly 60 on a couple of friends R3 shaft spines, so my tube is getting low. Went to Honda dealer today who said on the phone he had Moly 60 in stock. Got there and he gave me Honda M77. With my 15% discount and then tax it was $16 for 2.65 oz. Been doing some research tonight and I am not convinced this stuff is up to the job.

UPDATE: It is not. Don't waste your money on M-77 for use on drive shaft splines. Might be good for assembly paste, but not for drive shaft spline lubricant. Glad I still have some Molly 60 left.
