400/4 Wheel bearing questions ?
Sesman:
That’s the method I used, Ted. I guess it depends on your hub finish term of heat? I ‘warmed’ the hubs and froze the bearings over, but only because it was convenient to do so..

In addition to Bryan's observations, by locking that one bearing it positions the wheel as desirable from design (in effect a datum) with the "free" one just supporting wheel load as required. If they machined the free bearing housing to take a locking installation too, then that would require a shim pack/operation to distance the two bearings within the hub. Failure to match exactly would axially load both bearings or leave them slightly loose depending upon the spacer used.
This design effectively does all it needs without having to accommodate tolerances by shimmery :)

I think I have got my head round that concept - fix one on both side as the point where the drive load is from the sprocket - the other end just a normal press fit - spacers stop any end float load issues - axle spacers do the rest.

Ted, got the dishes, not been well lately but will try and get on them today if possible.

Absolutely no rush at my end Ken so don't go and overdo it on my account.
I've done nowt on my bike today my one job was to remove the airing cupboard door (3rd Time)) then trim another couple of mm off the bottom to clear the carpet. It's been catching ever since we moved back into our house after the fire rebuild in 2018. It took me about five trips up & down the stairs with tools less than 2 minutes with the electric plane - then an hour to hoover up everywhere - then another five trips up & down the stairs to put my tools away. Now I'm done in - after all my efforts the dam carpet still catches a little.
When the door Inspector comes home from work I know what's coming - "it still catches a bit but it will do" that's code for try again Ted.lol
To cap it all Wendys PC went Blue screen yesterday after a windows 10 update - I spent over an hour last night trying to sort it as the auto repair doesn't - it will not go into Command Prompt as it says there is no administrator on the system. I gave up this morning and dropped it off to get it fixed.

Fitted the first (smaller) rear wheel bearing today after a few days in the freezer in a zip lock bag - went in easily using my alloy bearing drift tool & a small lump hammer.

What no comments on my bling gold wheel?
