How do I stop the sprocket bolt coming loose?

[Drew]

Still not smoking then?

Nope. Getting easier though, sat around a half dozen smokers at the pub last night, gave in and had a drag. I fuckin near CHUNDERED.

Farkin hell,cant believe it took so long.

Gimme some credit, I didn't know what the bike was.

Here are some pics of the front sprocket assembly:

[Katman]

the nut is there just to stop it coming off, not to hold it tight.

The nut most certainly does tighten up against the sprocket.

(Well, against the washer that's against the sprocket).

[bogan]

So they use a nut that is supposed to be left loose? Suzukis eh!

[Katman]

Once the sprocket is in place the splined washer fits onto the output shaft and leaves a couple of millimeters of splined shaft protruding past the washer.

On the reverse side of the sprocket nut is a recessed portion which the protruding splines fit into.

The nut is supposed to hold the sprocket tightly in place. (I'll check the torque specs tomorrow).

While the cap bolt and speed sensor rotor that screws into the output shaft prevents the nut coming off the shaft it's purpose is not to prevent the nut from loosening.

The tightening of the nut is what prevents the nut from loosening.

I failed too. So I have to print a retraction of my acceptance speech it seems.

You tighten the engine nut to 115N.m, it is loctited in. then
you tighten the speed sensor rotor bolt to 25N.m

There is no mention of any gap.

failing that download the manual.

I'll buy some Loctite just to be on the safe side and apply that to the big sprocket nut.

Seems legit.
According to the parts fiche it should have a washer on the outer side of the sprocket

One of those things is imaginary, and one you wish was imaginary

surely not......

There's a leading bloody statement for ya!

[macka77]

loctite is correct. that 6mm cap screw has locktite from new, clean the thread and reaply super nut lock, or take it out otherwise it can come loose again. the large nut for the sprocket should be a lock nut similar to a nylock but uses a metal strip instead of nylon, but if you can wind the nut on the thread without it gripping the shaft thread the nut needs replacing , rear axle nuts are the same not many sports bikes use castle nuts anymore simply beause lock nuts are faster and better
