Don't take it apart - auction the damned thing for fortune! - Thass gotta be
the only Shimano derailleur in existence with 9 cogs on it!

I'm wondering if he meant cassette maybe?

And, I'm wondering if those are really rivets. The few I have played with
are held with thin, long screws that LOOK like rivets.

Those screws are on the way out. I used to buy 7-speed 11-28s; at first
they had screws, but they were replaced with rivets. The screws have
hexagonal heads at the base of the cassette (ie, the side that will be
adjacent to the hub flange); the rivets are round.

Dear Zilla,

Step 3: If you mean how to remove the rivets, reach for a
Dremel tool with a reinforced fiberglass cutting wheel (not
the cheap, thin, easily broken cutting wheels--you wanter
the thick, expensive ones with the ugly visible grid).

Step 2: If you don't have a Dremel tool, get one.

Step 4:The large (compared to other grinding pieces) round
edge of the wheel removes metal until the head is ground off
flush and then lets you grind a slight dent.

Step 5: You'll make some shiny cosmetic scratches on the cog
surface, but once the head of the rivet is gone, you can
bash--er, I mean gently tap the rivet out with a punch.

Step 1: Before doing this, however, consider if and how
you're going to put it all back together.

I'm not sure that's generally true. My consumption of cassettes isn't large
enough to detect a general pattern, but the last two non-spidered Shimano
cassettes (9-speed Deore-quality MTB) I've bought were both screwed
together. The 7-speed HG70 cassettes I used to buy were often riveted.

A hand file is cheaper, and will remove the soft rivet heads with
relatively little work. A centre-punch and drill will do the job too.

Reassembly isn't normally necessary. The sprockets can be slipped onto the
freehub body one at a time. The rivets or screws are there mainly to speed
assembly.

Thanks but neither of the links you posted mentioned
anything about taking a cassette (yes cassette) apart.

The Shimano link probably is wrapped in the post and you need to splice it,
or back it down and drill back to it.

The Park link will get you there if you leaf thru thier site.

I'm taking it apart to get the 16-tooth cog
for an SS. Re-assembly is un-desired! 🙂

In that case, consider buying a BMX cassette sprocket, like the Shimano DX.
They have taller teeth that reduce the risk of chain derailment, they last
longer, and when you've worn out one face you can flip the sprocket and
wear it out all over again.

Thanks. I'll do that in the future. In the meantime,
the "center punch" trick was the winner. It was
simple and effective!

ISTR seeing that some cassettes have rivets that are driven flush at
the big-sprocket end to begin with. I'd drill those out, myself. If
the head protrudes, then the Dremel would be one of the potential
tools to use.
