Mk1 has a castellated nut with a split pin and the nut is on the right-hand side. :)  Even shows up on the cover of the Haynes manuel.

 

I inserted it the wrong way last spring and had heck of a job getting it out as all the bolt had to be pushed through the tight bushing  :unsure2:

So - yes, take care !

Well this throws up quite the debate does'nt it, my axle is currently done up on the chain side which is how it came to me and i have pondered which is the correct way to have it !

You ave it rissole backads dabbers. Insert from sprock side, nut offside is how they came from yam. Mk1 this is.

I get the best engineering practice bit about rotation but don't get it on an axle spindle.

 

HGVs can have left hand threaded nuts on the left side of the vehicle if they are a conical nut fastening opposed to a spigot bolt. The theory (and practice) behind is the left hand thread will keep tightened in the direction the vehicle is moving (unless reverse gear is the chosen option  :P ) The same for centre nut wire wheel fastenings on classic sports cars, LH thread for left side of the car.

 

As the spindle isn't rotating on the bike then it's surely a case of convenience which side the axle goes in?  :pimp:

I guess they factor in the possibility that the axle might sieze to the wheel if it's not lubed. :unsure2:

Slightly different principle as the axle itself is rotating, and the nut is just retaining the wheel. Imagine your bearings are wearing in your wheel, and there is now a loading trying to turn the inner race along with the outer race. That in turn is loading the spindle and trying to turn it along with the wheel.
I agree the forces on a properly maintained machine are minimal, I just prefer to follow engineering practice. (The company I work for makes high speed packing machinery so we deal with a lot of bearings, shafts and similar parts).

Just that, Studley....

I'll bow to that  :drinks:  Now lets imagine the nut is nicely tightened up on the left side - the rotating forces on the spindle will be trying to tighten the spindle into the nut. All good theory  :cool:

Exactly, that's the theory behind it. I just thought it quite interesting that three tdm's all suffered the same adjuster plate pulling into the swingarm and they all had the spindle inserted from the left. Never seen it before on a bike, all my previous ones have been from the right.
Anyhoo makes for good theorem....😂

I understand all the tech stuff about seizure and rotation, but on a practical note, I insert from the left...oohh er missus....because I can't imagine the hassle of removing the spindle nut (potentially 150Nm) on the roadside using the 6" long marzipan spanner in the tool kit, even with the extension fitted. If the nut is on the right hand side of the bike, at least you can get your foot on it and push down, giving you half a chance. In the numbers game, I reckon there's more chance of having to remove the wheel away from home than a well maintained, greased and inspected wheel bearing letting go catastrophically......touch wood!!
