How do you lock the front sprocket, to stop it turning, when removing the sprocket bolt.

Rob

[Real McCoy]

I put it in gear and put a bar thru the rear wheel,no doubt some one will come along and tell you how to do it proper

[Triple Nine]

Um, don't think that will stop the front sprocket from turning Karl

[electricsheep]

it would work, as the chain is still fitted.

But I think that I need a longer breaker bar, as it just doesn't seem to want to move.

Just to double check, these aren't a left hand thread ?

Rob

[Triple Nine]

You can tell I'm not a mechanic can't you Rob

[marksduc748]

just knock it in gear and leave the chain on till you have it lose. and its normal thread. you wont need a longer breaker bar just shock it and it flies off.

[electricsheep]

I will have another go tomorrow with my mate there to stand on the rear brake and keep the bike stable on the paddock stand.

That will let me get a better position and use my weight. Then it should be no problem

What is the correct torque setting for this nut ?

Rob

[marksduc748]

i never torque it so cant help you there but it should say in the book.

[Real McCoy]

Iv told you how to do it ....Rap a bar of some sort in a rag,place it thru the rear wheel, slap it in first gear.
Then place a scaffold bar or something over yor ratchet and hey presto :P

The jumping on the rear brake idea can end in tears

I hear you,

I already have a 2 foot breaker bar, but i think the nut may have been overtighened during PDI.

I don't have anything suitable to go through the wheel (and I am worried about marking the wheel or swinging arm)

I will try with my mate, if that does not work I will go to a friendly tyre center and get them to spin it off with a air wrench (or what every they are called)
