Removing Front Sprocket

[mxpanda]

Can anyone tell me what size socket I need to remove the nut to get the front sprocket off my bike. Its a 06 450, don't know if that matters.

I believe I used a 32mm but I'm not sure. If I was home I could look in my toolbox to verify. Hope this somewhat helps!

its the same as your rear axle nut

I Think A One Inch Socket Will Fit

Yep, what he said, I use a 27mm.

You'd better have an impact sockect/ wrench to get it off though.

yep cause trying to hold that rear tire from spinning totally bites.....

You can however remove it with a very heavy person sitting on the bike with the rear brake on while you wrench

Another way, although somewhat controversial, is to jam something in between the rear sprocket holes and swingarm.

A sturdy 1 x 3 laying across the swing arm through the spokes works real well, too, assuming you haven't removed the chain already.

at last a better way than my old fashion stick the long handled screwdriver in the front sprocket under the cases method....

Grey no problems bending spokes? 1 x 3 all the way up to the rim, I assume?

That's the key to it, yup. ?

27mm-Engage Rear Brake while chain is still on.

1) Put in gear before engaging brake.

2) Remember what a pain-in-the-azz it was to take off and put some assembley lube on the spline, sprocket, threads and nut before reinstalling. You don't have to worry about the nut coming off because it has a bent-over retaining clip/washer thingey. I also like to use a wire brush to clean the whole area before installing the new sprocket.
