Rear axle is the same.
Front axle is bigger.
Forks are sorted and upgraded -- do not want to swap.
Any quick and dirty for putting the bigger axle wheel on the small axle forks?
There's issues with bearing thicknesses that will give you fits with spacers and the speedo drive IIRC. I might be wrong, but no easy button I'm afraid.
I was thinking of making a sleeve for the old axle and sizing it up against the bearings, but that might be suicidal..

I think it would work as long as the sleeve didn't turn. You might never get it out again if it welded it self to the axle because it was acting as a bushing instead of a sleeve.

didn't turn in relation to the axle? that makes sense, but i don't know how that could work...
oh well..
bore the forks?

I suppose you could use a sleeve retaining compound and locate the sleeve in the bearings. You could use all the stock parts
Loctite 640. I've used it to keep bushings inside worn out bores in tractors.
I'm running into similar conundrums, only reversed. Want to upgrade forks to SBK w/ 40mm calipers but keep 20mm axle wheels. Spacers and all that have my head in a warple.
I did this before I found the money for BST's
I bored the front wheel 1mm deeper for the bigger bearing to fit.
If it needs to be changed back I could make a 1mm spacer and fit the old bearing size.
I dont use them any more and was think of selling if anyone wants em. They have new paint as well....

I think it would make removing the wheel impossible later, no?
How do I remove the axle if there is a bush inside that is bigger than the axle mount?
I think this is actually the setup on the Pantah, there is a sleeve inside the wheel.. i'll take a look at that.. but it's not loctited, it is free floating. No bearing.

I'm not seeing that.
The sleeve would be inserted into the bearings and loctited to them. It would stay with the wheel. You'd have to heat the sleeve to remove it from the bearings if necessary.
The axle would pass though the sleeve like it was the inner bearing race.
There's a bearing spacer on all of them. Is that what you're thinking of on the Pantah?

yup. that's it. so you're saying to use the same bearings and the sleeve would go inside them.?

'zactly
It seems very do-able then. The sleeve would be installed before the wheel is installed.
Instead of the axle turning directly on the bearing, it would turn on the sleeve.
Hmm.. maybe better to use different bearings.. shit..

No, the axle doesn't turn on the bearings. The inside race of the bearing is clamped by the spacer bits and the axle and stays stationary with the axle. The outside of the bearing turns with the wheel. The sleeve gets clamped with the inside race by the axle.

The axle doesn't turn.
The axle and the inner bearing race are stationary being clamped by the spacer when you tighten the axle.
It will be critical the sleeve is exactly the same length as the distance from outside to outside of the inner bearing races when installed in the wheel.
I should not have said the axle turn on the bearing, I meant the face of the bearing is stationary against the axle, but i'm thinking about it from the axle's perspective if that makes any sense... i know it's locked in the fork, but i'm trying to get it in my head how a sleeve would be install-able
i wonder if i could modify the axle by adding a "pip" that locks into a slot on the sleeve. sort of how the axle locks in the fork when you ad the axle tool......
If you can get this made as a kit, and do a run of them, you'll sell them all. Also the reverse kit of running later 43mm forks with the stock wheel and axle.
Many of us have held off changing wheels or forks due to the cross fitment issue.
Isn't changing small wheel onto big forks a matter of fitting the right bearings and sleeve to use the big axle ?

it just seems pretty straight forward (hahahahahaha) to have a sleeve with some sort of slot that keys onto a nub/pimple on the axle to marry them and allow mounting of a larger axle wheel on a small axle fork.
You would install the sleeve into the wheel then slide the axle in. Hmm

So much easier one way than the other?

possibly.
Sorry, I was referring to the spacer that goes in between the bearings. I know it's possible to use the 20mm axle in a 25mm hole. I read it just recently. The nut part in the old forks that doesn't come out when the axle is removed is 25mm OD. That can be used on the small side of the larger hole forks. Where you need to make up the room is the other side. I remember seeing mention of using pipe of some sort with a slit in it that can be clamped.
What I want to do is use the larger size axle. If I have adjustable forks, I want to be able to get to those adjustments.

You don't need to if the sleeve is the correct length.
