Drive Spline greasing

[AberdeenAngus]

As mentioned earlier, by shift piece they mean sliding joint

“The paralever kinematics is designed so that no length change occurs, meaning no shift piece is necessary.”

Demonstrated by the fact that, when dropping the final drive, some folk have found it seized but were unaware of the fact.
Stick some grease on the splines to stop corrosion. Put some white marine grease on the gaiter to help keep the water out. Then forget about it.
If you find you’re worrying about it then by all means do it regularly. The frequency should be proportionate to how much of a worrier you are.
For me, I do it whenever I have need to drop the final drive (once). I wouldn’t drop the drive just to do it. But That’s just me.

Some people are unaware of a lot of things, and have a complete lack of mechanical sympathy just put fuel in it mate, don't know how it runs

so wouldn't notice anything like odd vibrations that might indicate a seized driveshaft spline, their the sort that wash their bikes with muc off

I don't agree there's No movement in the splines, of course there is even its only a few thou, and if you need to drop the F/drive or driveshaft, change the clutch, remove the gearbox and its seized you have a whole world of problems, check it , grease it , its not a big job, but could be a big problem if you don't

No, there are no cases of any drive plines failing. This post , like all the others are absolute nonsense.
Where are all the UKGser posts of failing splines

You are the only one who seem to have a problem with this, why is that? are you not very mechanically minded or should we have a whip round for a tub of grease ...

Its nothing personal. It simply doesn't happen. Its a complete manufactured hyped up story. Like I've said, If it makes you feel better greasing them, then crack on, but Jeeez, stop the persistant bull sh it threads on it.

I think its more about a rust issue when water gets into the shaft.

There's lots of rust on my car and van shafts. My van has three times the chances now of , .....well, .......what will happen ?

My concern is the splines almost fusing together. There is no way for the water to drain so it pools near the final drive.

What is the issue with lubing the splines? I can't see any negative

No issue. If you feel the need to do it. Do it ? I just disagree with post like this, Making out that if its not done, your pride and joy will explode Tossers will read this and believe that it has to be done. And that just isn't the case.
The splines don't fail. And if they rust, so what ? Its only an issue if you need to split it. And that isn't normally done. Just ride it and forget it. Stop reading these silly threads.

Really, there is no need to discuss such a metter here, even to exchange some insults just because of diversity of opinions.
I've done my splines when bike had 4000 miles. Whoever wants to do it, just do it. Who doesn't, just don't. But stop turning against each other. We are here to help each other, not to impose our opinion.
As for draining, I will make drain hole and tap the bolt as soon as the bike gets out of 3-year warranty. On my bike, there is even one mark at the bottom where drain hole shoud exist.
What I found strange, back in January when I went to pick up my new bike from the dealership, the salesman told me not to cover the drain hole on the bottom of the drive shaft as draining any possible water ingress was important.
What the hell was he talking about?????
Whatever, I'll do whatever I want.

This.

My hexhead shaft snapped, presumably due to water ingress. The spline area was covered in rust residues. Would greasing the splines have helped - yes, as I would have noted the issue sooner and correctly sealed the gaiter with Staburags.

The back wheel locking whilst filtering on a wet M25 wasn't fun.

If you don't look, you don't see.

Is you van driveshaft joining the diff in a semi-sealed state, with a boot preventing it from drying out?

The two things are not comparable.

If you want this thead to go away, leave everyone to get on with it. A yes it is, no it isn't argument doesn't last long if there is only one side. Neither side is going to change their minds.
I am sure it will come up again............

Think that this thread is heading downhill now so I’ll close it.

Many thanks for all of the inputs both negative and positive y
