Wheel swap intrigue

[Joseph]

Hey

I am wondering if the following technical solution would be viable :

Swapping a wheel onto a busa swingarm, i'm faced with the following issue :

Wheel bearing ID : 30mm

Busa spindle OD : 28mm

I've always managed to get away with adaptative bearings that slot in the wheel and on the spindle, but unfortunately there is no bearing made that would bring the ID to 28.

That leaves me with a radius of 1mm to handle.

I have read on here people machining a long spacer that slips into the wheel and goes to the outer face of the bearings.

I have found stainless steel tube that is 30mm x 1mm so that would give me the 28mm ID i need.

But wouldn't that prove to be too flimsy or cause any fitment/removal issue ?

Other than that, what options do i have ?

Cheers

Can you not open the slot up to 30mm?

busa,s don't use a 30mm spindle they have inserts that fit in the bearings 

items 2 & 14 ....i think i have a couple some ware

Yep thats what i said.

28 mm on the busa spindle, 30 mm bearing ID on the new wheel

The parts you mentioned are the hub spacer and sprocket carrier spacer of the the busa rear end. i'm using neither of those.

@Fazz711that means finding a spindle that would fit in the busa chain adjusters, which would also need opending up. Sounds doable but spendy, i'd be happy to use a cheaper option if there is one

I used sleeves on 20mm wheel spindle in a JMC swinging arm with a MK1 busa back wheel.

Right so that means a 4mm wall spacer through the wheel ? 

I'm just thinking that a 1mm wall tube may prove problematic ?

The one in the picture was done in 3 sections. So long as the tube is a snug fit I can't see it been a problem.

Just something to keep an eye on in terms of wear as it's not a hardened surface.

Worked better than the worn out chain did lol.

fair play.

Right i'll give it a go.

This is for my main ride so it'll be getting mileage

Keep it all tight, bearings will do work.

I don't really see a problem. Make a new internal spacer with a 28mm id. Use stepped  captive spacers each side with a 28mm id with a 30mm od step. The rest of the spacer can be whatever diameter works best

Wall thickness isn't an issue with wear.

None of it is rotating other than the bearings.

Can't see a problem with a sleeve, as above it the bearing's that are moving not the spinal, or theses something very wrong 

[Joseph]

Right so for once it may be as simple as that. Would make a change 

Thanks to all
