Not sure what these are called in the manual, but the two large bolts clamping the front brake parts together - what are the torque specs for those?

There is one torque spec there that still puzzles me today.
It's about #22: the front wheel axle nut. Early 80s I did torque that nut @ the recommended 5,5 - 6,5 kg-m (39,5 - 47 lbs-ft), only to find out the wheel wouldn't turn anymore. I loosened the nut up again and all was fine.

The official Shop Manual Honda CB500-550 is found in Aladdin's Cave in a good resolution.

That doesn’t sound right, might be incorrect spacer between bearings? Worth checking out!

If I'm reading the post right that was 40 years ago so a bit late in the day..

Certainly there's no way a correctly assembled wheel spindle arrangement should tighten when that is done.
Agree it would point to something being wrong or out of place to do that.
Recognise that the date here may have impact, but believe same bike is still in use ?
More to the "engineering" point in detail though, that eventuality should absolutely not inform how the assembly is set for anyone, now or then. Clearly advice originating from that is false.

Why I torqued that nut? Probably to use my then new torque wrench. ;D I must have had my front wheel out at the occasion to replace brake pads or so.

Could you please paraphrase your last two sentences?

The original fault should be investigated and not an adaption made in how it's assembled.
A torque setting is always put there for a specific reason.
