Svedberg's RVF Race bike

Totally inspiring work sir!

Absolutely stunning.

Cheers guys! Project's on the back burner as usual, but I've finally started adapting the works RS250 axle to fit the bike. An SKF IR45x50x35 inner bearing race is ordered, and I've machined the missing big nut and spacer for the wheel side.

Soon we'll have better weather, and I can seriously start shaping the bodywork in the sun bit messy job inside my shed.

Sorry to drag up something you did ages ago but im just getting round to putting the axle on my bike, i gave that bearing code to a bearing company and they come back with a inner race for a needle bearing @£13.06+vat, is this correct?

Also did you sleeve the axle to take the NC wheel?

[L.Svedberg]

Hi!

The part you need pressed onto the axle is indeed the inner race for a needle bearing, same dimension as the corresponding machined surface on your std NC30 shaft. No, there's no need for any sleeve to fit the wheel, it sits perfectly on the HRC shaft. If you have the correct (outer) nut/spacer parts, that is.

Good luck! Lasse

Thanks for confirming that lasse, i will get that ordered. Is this the only part i need to get the hub fitted?

As for the wheel, mine does sit squarely on the axle but the OD of the axle is smaller than the ID of the wheel hub where as on the NC axle the OD id the same as the wheels ID so it fits snugly.

Ive no doubt that when the pins are in and i have a flat spacer it will hold the wheel straight just wondered if you had considered some kind of sleeve on it so its fits snug.

Not wanting to take over your thread but half the info is already here so seems pointless starting a new one.

The bearing race has arrived

I take it it needs pressing onto furthest part of the hub?

What did you use to do this and is there anything i need to do beforehand as theres no way its coming back off once its on there.

[L.Svedberg]

Hi again!

On my axle, the press fit was not a super tight one, and it was sufficient to put the axle in the freezer for a few hours, and the bearing race in the oven (approx. 70 degrees C) to get it to slide on with no special tools. I also used some Loctite cylindrical locking agent (make sure to clean the surfaces with a strong cleaner first) to make sure it sits securely in place. The bearing part goes all the way to a fully seated position on the axle, yes.

Sorry for the late answer!

Nice axle! The ohlins steering dampener, aluminum catch tank, and BB are nice too. LOL!

[Drunkn Munky]

Thanks for the info lasse. The spacer that you machined for the NC wheel, does it have a lip that sits inside the NC wheel? Looking at the pics of your spacer it doesnt look like its sitting flat on the surface.

[L.Svedberg]

Hi!

Yes, the big, recessed alu washer has a lip designed to keep the NC wheel centered.

ah hence why you didnt need to sleeve the axle, massive thanks again lasse
