Front sprocket bolt

Post by The Hurricane on Wed 01 Aug 2018, 12:59 am

Which way does the front sprocket bolt undo. I have put a piece of wood in the rear wheel to lock it up and have tried undoing the bolt both directions and it won't budge but I didn't want to force it if I am going the wrong way. Any ideas please.

I'm 99% sure it's just a standard thread. Mine's alway a pain to get off as when the sprocket is turning anticlockwise it's effectively always tightening the bolt up

It is as James says, I put the engine into gear (first) to stop the bike moving. I use a breaker bar that is just over 3 foot to get it to crack loose. If you only torque the nut up to 55Nm (the Hayes manual information) it will not come loose but will come off with a using breaker bar. Done this a few times and not had ant issues.

I have to chock my rear wheel every time, I tried it in gear and with someone standing on the back brake - I moved the bike forwards so just use wood through the rear wheel

Agreed you need a long tube but use a socket with a bar on it rather than a rachet handle.

Or a ring spanner and whack it with a rubber mallet.

Cheers everybody for your replies. Watched a video on Youtube of a fella undoing his on his CB500 and undone mine this morning and I think the weetabix helped.
