I'm planning to remove the primary cover this weekend and torque the sprocket nut to the new value. Does anyone know the size of this nut? I just want to make sure I have the correct socket at hand. Thanks (posted in Knowledge Vault but no replies).

Jon,

I recall purchasing a 1 3/16", six-point socket for torquing the sprocket nut on my 2003 XB9S. Can someone verify this?

I am in mid doing exactly that right now on a '04 12R. The proper socket for the nut is a 1 and 1/8".

I was surprised to find that a 1-1/8 fit a little looser than I would like to for that kind of torque..a 28mm fit a little better. 28mm is 1.122, 1-1/8 is 1.125. That little .003 sure felt like a lot more.

Thanks Al. Saved me having to go and buy a socket. I have a nice SK 6-sided 28mm collecting dust in the toolbox.

You'll probably have another one to do Jon... I just have to order the parts from Freedom....

Cheers

Maybe the difference between 6pt and 12pt?

Is it a metric nut? If it is, then I would think a metric socket would fit it a little better, no?

The difference is more than likely due to different "socket" manufactures. I just replaced mine and my Craftsman 1 1/8" 6 point and 12 point sockets fit just fine. I would recommend the 6 point because it has more surface contact with the nut. You'll want every bit of it with the higher torque.

Check out the black oxide finished impact wrench sockets your local auto parts store. Including the "special purpose" sockets.

I found a 32mm one intended for use on GM front wheel drive cars that is perfect for the 1-1/4" Buell clutch nut. It is a six point with extended reach and the extra length gets you solidly on the nut and lets you buck the turning forces with your off hand. It was only $7 or so.

Take a measurement with your digital inch/metric LCD caliper and go shopping. You get a lot more respect at the auto parts store when you come in with a caliper in your hand and looking like a machinist.

LOL. Thats what I did, walked into sears (which had the best selection of big sockets) holding a caliper. Worked great.

Once the nuts get that big, the fact that there is some wiggle is not nearly as big a deal. To round off the edges (even with a 12 point instead of a 6 point socket) would require rounding over a massive amount of steel.

And then you got your socket and wrench adjusting shims.

My Dad had a small metal tobacco can in his tool box that included a number of short pieces broken off of hack saw blades. They had the teeth blunted and one or two of those slipped into a socket would tighten up a loose fit and sometimes save the grip on a rounded off nut or bolt.
