Rear axle safety

[blacklightning]

I'm looking for suggestions on how best to safety the rear axle, nut and caliper on my 03 cbr600rr.

And, what size is that nut? 33, 34 mm?

Is it better to drill the corner of the nut, or go all the way through and pin it?

Nut is 32

I'd pin it... i believe it's 32mm

Just drill through both, or look for a castle nut?

tricky mike modified my nuts, works nice and safe now

You can use one of those big Diaper style pins. Cotter pin sucks

isn't it a castle nut already? If not, does the axle extend past the nut when torqued? does that have drilled holes?

I use pin through it, and safety wire the ends of the pin together to prevent it from sliding out.

Although I have seen a lot of people just have a pin through the axle and have never seem them get shit for it...

the rulebook I believe states that you must either wire the nut itself (i.e. from the nut to the swingarm or something, this is what I have on my tard), or go through the axle AND the nut (this is what I have on my R6).

My R6 didn't come with a castle nut but I found a castle nut that fit, the big pin goes through the castle of the nut and through the axle, then I safety wire the end closed.

I loosen the bolt/nut I wish to safety wire. Then I torque it to the correct specification. Mark where I wish to drill. Remove the nut/bolt. Then drill. This way I do not end up with a nut or bolt with extra holes because I did not take the time to do it correctly the first time.

Above is the best/easiest way.

Although, I have also taken the time torque correctly, and drill through the nut and axle.

I then use a clip/pin each time ... tightening the nut just enough to get the pin in it.

This saves some time as you don't have to re-torque each time.

With a nut that big it's also possible to drill a safety wire hole between adjacent flats - the hole passes from one flat to another a little below the point. If I go this route I do it to all 6 points so I have the best chance of having the hole close to the safety wire reciever.
