Should the axle just slide out the right side after unscrewing? The axle isn’t unscrewing anymore, yet it refuses to come out. Any tips would be great thanks!!

Yes it should slide out, it can rust and then it seizes in the bearing inners within the hub. The whole wheel may need to come out so you can force the axle out of the hub after the brake has been taken off. Always wipe some grease on it when reinstalling to sto repeats.

Thanks Kommando! If it unscrews without issue, what’s the axle actually rusted to? Sorry, I’m trying to get an image in my mind to figure out what it’s actually rusted to!!

Thanks so much again!

The 2 bearings inside the hub have a spacer in between them, the axle is seized inside and the spacer is free to turn.

Alex: I have a slightly different opinion. Given that all the bits are pressed together through the center of the wheel when the axle is threaded in, if you are able to unthread the axle so that it has come part way out it must be coming through all center the bits because those bits cannot move laterally. I think is just tight but free to be drawn out with some effort.

Hi Gordo!!

The problem turned out to be the speedometer gearbox was on there super tight. I greased the axle, and managed to remove it by lightly tapping it down the centre axle using a hide mallet. Re-greased everything and it all comes apart much easier!!

Next step is to learn how to replace a tire while not ruining 3 brand new tubes (grumble grumble).

Hi Alex,

Here, local garages and tyre shops fit tyres they supply for free, £15 for a tyre you supply. Given decent tubes are £15 ...

Regards,

Ouch! $15 a wheel labor here to change a tire and tube. It would pay you to upgrade your tire-changing equipment!

I stopped believing for a little while this morning. Journey is really going to be upset.

Get yourself a Breezer tyre tool .
Photos & instructions about 1/2 way through this thread mounting new tyres on 70 A65L
Some where on the web there was instructions for making one from some alloy rod.

Found it
Dans bike repairs page.
I had a flat on the M20 on a club run some long time ago & another member popped myself & the wheel into his chair to go home & replace the tube while the rest of the group had a long lunch stop.
His eyes popped out of his head when he saw the tyre off, tube replaced & tyre back on before the kettle had boiled for our cuppa.
He borrowed it and made some slightly longer ones , about 12" against the 8.5" original . I tried one of his latter on and despite what I had been telling girls for decades ,the extra few inches did make a big difference
HE also did a bigger version again in steel this time then made 2 steel rings welded together at right angles so one went over the handle end while the other end slipped over the axel thus making tapping the tyre off even easier
But even with the short original, you will never ever pinch a tube again.

And another variation on the same theme @ $ 40 ( inc postage ) it is about 1.5 x a tube price Stubby on amazon

You’re amazing thanks. Getting one very soon! In the meantime, I’m glad I did take it in, as they found a defect with the front tyre. Whew!

If you can not read the instrucion that were posted I can rescan them and PM them to you.
The one thing omitted from the instructions is LOTS OF LUBE.
When doing a rear, work on the plain side . not the sprocket side cause you can not get it flat enough with the sprocket in the way.
Like a tyre changing machine the tool need to be held so it is at a radius position.
Pull back with the hand holding it so the grove rubs on the outside of the rim and smack it hard.
I found small lump hammer worked really well
Like all new tools takes a litle getting used to but way ease than levers and far less likely to damage the tyre or rim.

no, your instructions are clear. i copied them down in case the world ends. i have some bald tires to swap out soon, so i'm curious how it works.

sometimes a good idea just never catches on for murky reasons. maybe this was one of them.


i have no idea what i'm doing.

The motorcycle industry changed over to cast wheels almost overnight.
They are about 1/2 the price to make but could be sold for a lot more and of course opened the door to tubeless motorcycle tyres
The makers of tyre changing machines suitable for motorcycles were caught flat footed by the change and it took quite a while for machines that did not distort the soft alloy rims to hit the market.

The Breezer was the answer, particularly for bike shops where scratching the wheel during tyre change could result in warranty claims.
I was good friends with Alan Bradshaw at the time ( the privateer who beat all of the worlds factory 125 teams at Phillip Island ) who was spares manager at the biggest Yamaha dealer in Sydney
The RD 250/350 took Australia by storm but they were fitted with the Japanese Dunlops so most new bikes got shod with Michalens or Parillis much more suitable for the pocket racers.
It was he who introduced me to th Breezer which was the tool they used in the workshop.
Honda then followed up by fitting the pressed / cast alloy wheels to their entire range save the step through & 750/ 4.

A few years latter the Alloy tyre changing machines came out and as the early alloys all had deep rims, most riders took their wheels to the shop for fitting.
Al set up a stand alone motorcycle tyre shop in order to amortise the cost of the new machine and even the competing shops took their wheels there for tyre changes.
Thus the market dried up just as quick as it was created and being that breezers needed a hammer , they did not become part of the riding tool kit.

Back when I was substantially stronger than now I could grip the tool and a spoke in one hand and work it around the rim to remove the tyre, but since then I have learned how to adjust the clutch a lot lighter so the left hand withered.
