front axle

SP_BOTT · Post by **SP_BOTT** » Fri Jul 13, 2012 3:00 pm

Hi, bit of a thick question, but I cant get the front wheel axle tight? It appears the threads bottom out but I can still turn the speedo drive through the fork tang (ie the bottom legs can be sprung apart easliy)
I've got the speedo drive in, and the RH spacer. (wheels newly powdercoated with new bearings, replated axles and spacers)

Am I missing something obvious? or doing something out of sequence??

Try putting the axle in from the other side.

Have a look at the parts fiche to see which way round the axle should be fitted from.

I might be way off the mark with that though

Good idea, never even thought of that, I did put the short bit speedo-drive side?

The little lugs holding the speedo drive housing soon get rounded and can twist out

Well I'm still having trouble with this, had the spindle and wheel out a couple of times, and it's still the same, tried in both directions and still appears to bottom out, and the wheel isnt tight, any other pointers or help please??
all bearings and spacers look to be correct with nothing missing? been through the manual and all looks fine

what is it like with spindle through speedo drive, wheel, spacer and into nut and tightened out of the forks.

Do you have a Kr1 or Kr1s?

my guess is , are the bearings the correct ones, and are they fitted correctly.
right bearing pressed in until it bottoms out and then speedo side pressed in gently until there is no free play on the spindal,
if the bearings are fitted correct, and you have the spacer and speedo drive
fitted, it should be fine [is the spacer ok, it has,nt been shortened, has it

I tried it without the wheel, and it seems as though all bolts protrude through perfectly, (each end of the spindle sits just about flush with the fork outer, and just sticks past the inner face by about 1mm)

My suspisions were the bearings too, but they were direct replacements (all fitted correctly, it's the sort of thing I do for work) what are the spec, just standard roller bearings I assume, not thicker jobbies?

I do have a spare bike I could try and swap the spindles over with? but cant see the need, as I only have this one in bits?

BTW it's a KR-1s

Was it ok before the bearrings swap ?

do you have another spacer you can try/measure ?

maybe you just have the wrong one.

Another update before it gets torched

took the spindle out my other bike (or more specifically a wreck) and everything measure exactly, or as close as you can without a micrometer. Put both spindles together side by side, and there's no difference, swapped them over and still the same??? (forks spring open, and speedo drive turns)
is everyones the same and it's not been noticed before? highly unlikely I would imagine.

So what next clever people?

This is without the pinch bolts tightened or fitted so far.

Didn't check it before Jan as I just took it apart as you would a restoration project. Nothing looks untoward or machined/filed etc and the bike looked very genuine and original.

Sure someone told me once the KR and S speedo drives are different

I Know the axles are different but have sold all my KR running gear so
can't compare the drives

Perhaps one is narrower than the other

Do you have a front wheel from the other bike you can use?
Put the new refurb wheel in the other bike.

Have you riden the bike before or was it a project from the start,

Do you have the old bearings to compare with,

Any bits missing from inside the speedo drive.

Will give that a go I think, got to jack the wreck up, swap speedo drive first, try my refurbed spindle in that. Was always a project to me, all I did was start it then strip it, bearings also hit the bin a while ago, but might have one left?
On nights so will try a wheel swap when I'm day off, and speedo drive looks like the one off the wreck too.

Thanks so far.

This is a bit of a tricky one!

I have a bare Kr1s wheel, would you like me to measure from the bearing to the lip just to make sure your bearings are in deep enough?

And if you poke your finger through the bearing onto the spacer between, is it loose at all?
