I advise you not to listen to anyone else on
this subject except Al Muzi.

During the Russian revolution civil war the
Reds didn't have any visible rank system to
tell their soldiers apart. Still, everyone knew
who was the boss. A good system, I'd say...

Otherwise tighten firm and not real tight.
I think that the "crash" you're talking about
is the serrations/semi-ratchet teeth on the
inside of the lock ring. These are to keep
the lock ring from backing off if it isn't
tight enough.

So, the lock ring bolt has serrations on the
inside that has a semi-ratcheting property...
but contrary to a real ratchet which goes
"chirr chirr chirr" this goes "crash crash
crash" with proportionally the more power in
between and larger chunks of movement?

Man, I have a bucket of worn out cassettes.
Perhaps picking one apart is educational...

The cassette should NOT rattle. If it does
there is an incorrect spacer.

I don't know if "rattle" is the sound.
When fiddling with the cassette some two or
three (?) sprockets were moving along, possibly
making some sound, actually I don't remember,
but if they did it wasn't very loud or alarming
in character. The sprockets were not spinning
but the amount of force to make them move was
minimal. They seemed to be moving in small
chunks. The cassette was brand new as said.
When I put it on and pulled with the ratchet
and socket, it crashed into a new position
I think three times, and possibly if I had
continued to pull, I could make more such
sounds/movements. With every crash sound, it
moved perhaps 30 degrees.

I assume that you know the difference between
a freewheel and a freehub.

OK?

If you have a vernier caliper you can measure
the spacers and let Muzi know and he can
straighten things out.

This particular cassette is already on a bike
but I will see if I can pick apart another,
spent cassette and get back to you. However it
could be another brand but why not.

There is no lockring bolt. Its a serrated locking ring that screws into the cassette body.
