Axle nut split pins?

[Pussy]

It generally goes like this:

Most (if not all) Kawasaki road bikes have castellated axle nuts

US and Canadian spec Suzukis do, too ( except the K7 onwards GSX-R1000)
Australian and European spec Suzukis have a locknut on the axle

Yamahas seem to be the same... castellated nut for US/Canada, lock nut for rest of world

It's just how different countries/markets have as design requirements.

Most NZ new Suzukis are Aussie spec, though they do bring in Euro/US/Canadian spec bikes too.
Most NZ new Kawasakis nowadays are Canadian models

Hondas seem to be Aussie or Euro spec

I must have an anomolay , my 2 year old Hayabusa has no provision for a locking clip and seemingly that was a design decision ? Why would your ZX6 have a clip when my bike does'nt , given the huge difference in HP's, weight and stresses combined....?

As below it all depends on the market it was designed for, some markets have different standards than others.

Is your axle nut just a common garden type variety nut, or is it a nylon locking nut or similar?

It's funny when you start looking into which markets the bikes we end up with come from. It can change depending on the strength of the NZ dollar or if a change is made in the intended markets legislation that won't fit our rules.

It worries me that you know so much about nuts.........


Are you a pussy or a squirrell?? Or does your nut fetish extend to the furrier type??

You'll get a kick in yours if you're not careful......

I thought they all had split pins?! Oh well. I see my swingarm pivot bolt has no split pin, it has a castellated nut instead. That would do just as well for an axle bolt.

I like have the cotter pin though, adjusting the chain every few weeks is a lot easier when you just straighten and pull the pin, back the nut off a few turns, rinse, repeat. Castellated nuts are just a pain in the arse if you're in a hurry.

Can only make the cotter pins last three cycles before it's too mangled to bother with -- my little box of them is nearly empty

the Triumph has what looks like a Nylock nut, but the insert is metal. Presumably a longer lasting alternative to nylon but serving the same purpose?

VFR has a big-ass 36mm locknut.

I was looking at an endurance racer in a magazine and they use R pins instead of splitpins. and ziptie the R pin shut. belt and braces.

I've never sen a cotter pin on a motorbike, but I've seen people call split pins cotter pins. I've always known cotter pins as a plain, round headless pin with a flat taper on one side and a threaded end that aligns and the taper clamps to a corresponding rebate in the adjacent part - as found on non-one piece bicycle cranks with separate crank arms.

Castellated nuts are meant to be used with a split pin - if there's no corresponding hole for a split pin, it's the wrong nut. You need a spring locknut.

Nylon locknuts are supposed to be single use in critical application whereas the spring locknuts are reusable. The ring is spring steel and the deformation which stops the nut from shaking off is not 'plastic' when fitted (i.e. it returns to the original shape when removed).

Both H-Ds at Chez Scumdog have castellated nuts on the axle bolt, I use an "R" clip instead of a split pin though.

Yep that's a cotter pin. You ain't ever looked closely at the kickstart of Briddish scrap iron. Almost always a cotter pin. I got a box full of flogged out cotter pins. You can always tell the bikes where the cotter pin's stuffed at a glance. The kickstart lever will be almost horizontal.

Guilty as charged!

I'm probably using all the wrong words then. I called them cotter pins because that's why my RS Haynes manual calls them. Perhaps my RS really was fitted with cotter pins on the axles originally?

I thought the Haynes called the swingarm pivot nut a `castellated nut' too, but in fact it calls it a `self-locking nut'. At any rate it looks like the thing attached to the axle of a TRX850.

Cotter pin is the phrase in common usage in the US to describe what we know as split pins. I haven't yet established what they call cotter pins although an American pal says he calls them- cotter pins.
When I worked in a bike shop in Welly in the 60's my boss used to throw away the split pins that were fitted to all new Japanese bikes of the day. His response when questioned about this was to ask "when did you ever see a rear axle come loose"?
These days I like to use R clips even if a split pin was fitted as standard.
