rear wheel tapered spacer???????

[jerry]

Which is the correct way to fit the rear wheel tapered spacer on the sprocket side ,is it with the taper towards the wheel or with the taper towards the swing arm?


Ducati John says its with the taper towards the wheel bearings .

None of my manuals or parts books Haynes ,Ducati or DT shows the correct way???

I'm fairly certain it's taper towards the wheel, as Ducati John says.
You'll know if you have it wrong, cos if it's wrong once the wheel spindle is tightened up the wheel will bind and be difficult to turn.

^^^^^^^^
what he said

[Scotty]

easy to remember is the flat bit against the swingarm and the pointy bit against the inner bearing race

[jerry]

thats what I thought

[JimmyF]

I had the rear wheel off yesterday, definitely taper in

[jerry]

thing is where does it show it in any Ducati paperwork?

It doesn't!!!!!

Oops.

I'm pretty sure I have mine with the fat bit against the bearing, and the thin bit against the swingarm.
Can't say I noticed it being hard to turn...

better switch it round I guess!
:S

Tried mine both ways round yesterday, it was taper outside and can't say it made a heap of difference. It depends on how far the spacer on the sprocket carrier sticks out. If it's enough that the spacers thicker end clears the carrier it's OK, if not then its not.
Taper side in does then make sense so mine is that way round now.

this extract from the factory manual is fairly unambiguous

Time to switch it round then!

Come on guys, think about it.

The inner/smaller part of the bearing stays still, it sits around the axle which dosent rotate.

The outer part of the bearing is tight in the wheel and rotates with it.

The thicker part of the spacer sits against the swinging arm because it spreads the load so it dosent damage the face of the arm.

The thinner part of the spacer is thin so it only touches the inner part of the bearing, the bit that dosent rotate.

If you fit it the wrong way round:

The thin part concentrates all the force in a small area of the swinging arm and will crush/damage it.

The thick part will push on the outer part of the bearing which is trying to rotate.

So either the outer part of the spacer is rubbing against the outer bearing race or the inner part is trying to rotate on the inside of the swinging arm.

You've bypassed the bearing.

Come on guys, think about it.

Where's the fun in that.............he he............:)

[DevilBoy]

When you put it like that!

God, I hope I haven't knackered anything.
I went out with it the wrong way round last week!
gulp.

My S4 has been the wrong way round for 10,000 miles and the rear wheel bearings are fine , but I have changed it around now .

The M750 is the same !!!!!!

just looked in the Ducati showroom in Bangkok and there are 4 bikes in there with the spacer round the wrong way.
