I confirmed the shim washer was present on stub axle one removed.
Yes the flats of stub axle were cocked in the SA slot, and the loading from the axle nut torque must have forced the deforming of slot and corners of flats.

Will see how much it can be cleaned up, file or dremel. The stub was jammed in place tightly and needed lots of drifting to get it out of slot. There are some damaged threads on stub where it contacted SA slot on way out I guess (had the nut on left end to protect those thread while knocking with deadblow hammer).

These days I trash all that stuff and install the single axel. Doesn't cost much more than the parts you may need to change, and you already have the sealed bearing. The dummy axel, felts, retainers, and PITA bearing spacer all go in the trash. Adding or removing a half link in your chain (if possible) would likely get you away from the damaged area of the swingarm. Of course, a little welding or even brazing would fix it as well.

If you want to stick with stock and can't find someone in CA to give you one let me know - I should have a good one, I can give you, but the postage is terrible.

Thanks for the offer. I see my regional supplier is listing stub axle in stock for $49 CAD. Don's on line store shows $70 USD for his axle setup (thats about $100 CAD plus another $25-35 USD for DHL and brokerage I imagine). I've PM'd him to see if his quote is any different.

Don't forget the hub final sprocket which is very worn out , the new chain and the new front sprocket . $.

I do have a NOS drum-sprocket and a new chain. The orig drum teeth are showing some shark toothing, at 17k miles. Though hardly any chain play when wrap around teeth, pulling chain away from rear direction.

All 3 must be replaced as a set.

I’m with Greg, fit a solid axle and save yourself a lot of trouble. All you’ll need to do to the swinging arm then is de burr it.

Does the one piece axle still have flats engaging with SA slot?

No, there’s no need, it’s just one long bolt clamping everything together fully without fuss or faff…

Now you've done it! Order placed with Mr Pender. Just gotta hold my nose as I hack off the $50 USD pound of flesh for DHL.

Then Don got at least 2 orders today.

Ya, I've been complaining about the ever-increasing cost of shipping. I used to pay Amal 40 GBP no matter what I bought. My last order was 175 GBP! I just received 10 more oil pressure switches from Don and he had to charge me $5 more each to do slightly more than break even due to shipping - makes no sense now for me to sell them unless as a part of a big order.

As bad as that is, in Apr 2022 I bought a 6-pack of 30.5 oz Folgers Classic Roast coffee from Amazon - $42 delivered. Checked yesterday, now it's $86.45 - more than double and the local grocery store is even more.

...and it's easier to change a rear wheel with the one-piece axle than with OEM - just ensure the nut is on the right.

Just curious. What is the reasoning behind the nut on the right?

You can then leave the axle poking through far enough to hold the drum and sprocket in place, thus kinda keeping the QD function.

Got bearings out of the drum (double row) and two single row out of hub. Noted appearance of blue grease that I found a few yrs ago in the SA spindle from a DPO. So it seems likely these bearings had been replaced in the past. But will fit new sealed types.
Waiting on Madass's one piece axle. Does the original spacer in the wheel hub go back in 'tween the two single row bearings with the one piece axle or is something different provided with it?

The wheel hub is unchanged. The brake drum is where the changes take place.

DHL just delivered the one piece. Not bad for collection it on Monday from Don to my door Thursday. $50 USD inital shipping, then another $22 CAD direct to DHL "for taxes and duty". No actual breakdown of that added fee. Fully expected to have to cough up for fed/prov sales taxes (15% on total). So with exchange rate, the amount isn't out of line.
I did request Don use the Canadian tariff exemption code for antique vehicle parts so that may have helped.

Axle looks great. Need to fetch it up to the swingarm to see how it goes.

Shipping is complex nowadays. Always ask for the antique/ historical exemption from duty.

Heard from Don. Apparently he penciled in a low item value to help with my costs. So that means $22 extra fee was actually only a DHL "brokerage" handling fee, plus tax on that fee. So basically I paid $70 for DHL shipping on $60 USD item.

Can't get pissed enough to do anything further about it. Just happy to now have the axle and wheel back together with refreshed bearings.
