Sprocket carrier bolts

One for the guru's

I checked my "nuts" the other day (as mentioned in another thread, which I can not now find).

I tightened two then the third one snapped clean off

, not a problems say's I, I have five spare (I replaced the sprocket carrier not long after buying it as the bolts were loose and the holes were oval

)

The other bolts "shoulder" are too large (about 1-2mm), meaning the carrier wont seat, I find this strange as I would have thought the bolts would all be the same from RSV - Falco

.

I await enlightenment from the great & the good (I will leave it to others to decide who's who).

Forgot to mention the new set are allen head internal, the set with the bike are hex nut.

Really check the height of the new retainers.... They are what makes the speedo work... Ask me how I know!

Did you buy them second hand? They may be for an aftermarket sprocket....

No they're not ...... Mr Aladin has gone into donkey-mode .... perhaps we should ask him how he knows - LOL

The speedo works off of the REAR BRAKE DISK bolts NOT the Rear Sprocket!

I'll have 50p on Moose meaning disc not sprocket and 50 quid on alad being a donkey..

I'm betting he means sprocket .... as that has a carrier and the rear disk doesn't.
No argument about Alad the web-hoofed donkey.

Moose which of the various bits in the pic are you referring to - especially those being a different size?

Hi

Kwackerz you are out of pocket

I do hope I know the difference between a sprocket & a disc, or I have been lubing the wrong thing for 30+ years

D-rider item 9.

Alad, I bought the sprocket carrier and bolts (Spring drive fixing bush, to give it its proper title.) from a breaker on e-bay, so second hand.

The thing is, if they are aftermarket, they wont fit, as they hold the carrier off the wheel by 2mm approx, meaning that crud can get into the hub and the internal spacers won't meet

, I wonder if they are from a Futura?? No they are not, just checked, oh how I enjoy a conversation with myself

.

I am having them turned down so they will fit, though thankfully I only need one (at £10.88 + vat + delivery

)

Never doubted you old bean

Had to bet against simply so Alad didnt think we were ganging up on him..

As if we'd ever do that?!

Hey Moose,

I was initially confused (normality really) I thought you were saying the pins were too big in diameter and wouldn't fit in the holes, but now I think you are saying that they are too long, please confirm for the hard of understanding!

If they are too long your 2mm commnet makes me think that the carrier/pins may be from a later model. Isn't the back wheel of '04 and up Mille's a couple of mil wider than the Falco/early RSV?

In which case I'd just file/grind them down a bit. If it's only one that's broken use the 4 good ones and one trimmed one. I can't believe you would have to be absolutely accurate as the pins are pretty long and don't transmit forces by bearing on their ends.

Good luck

The hub of the front wheel is wider on the later RSVRs - that is to align the discs/calipers for the "radial" brakes.

I didn't think there was any difference with the rear.

Just checked the part numbers and there is a difference between Falco/early RSV and later RSV's. Not difinitive proof, but a good indication that there is a difference.

I'm convinced there is a chain alignment issue with the later model swingarm conversion and that 2mm was the give away.

Moose, compare a couple of the pins and let us know.

deffo agree the front radial hub is wider, 5mm IIRC, but certain the later rear is slightly different too.

Pierre???

Ah yes ..... that chain alignment thing rings a bell .... I think .....

The pins are the right diameter and slightly longer about 2mm, this isn't a problem (though I have had one shortened just in case)

The problem is the shoulder/lip/stop which is too thick, when fitted loose in the hole you can see it protudes about 2mm beyond the wheel edge (item 4)

I have checked that all Item 6's are fully home, which they are, because of this protuberance* the sprocket will not sit against the wheel, leaving a gap of around 2mm.

I will take some pictures (before and after) and post when I can.

I did also wonder if on later models they made the rubber bushes thinner (item 6)?

*I never thought when I woke up this morning I would taking about protuberances

Now I understand.

I'd be tempted to cut the rubber down to fit.
