How do I remove this old Dura Ace freewheel???
There is no place for a removal tool to fit. I can get the plastic cover to rotate, but it does not unscrew.

2 chainwhips, I think it's actually a cassette.

Even the clear plastic spoke guard says "Freehub Protector."

I used those on a couple of my early custom XC-racing MTBs (early '80s) because the high gear (like Nigel Tufnel's amp) went to 11. That was probably the first 11-tooth cog I ever saw, though Suntour made them too, for thread-on freewheel, a little later I think. With an 11 in back and a custom-made adapter to use freehweel cogs in front as a granny gear, I had "Micro-Drive" way before anyone else! I had 18-32-42 by 11-24, and a short-cage Dura-Ace mech shifted all the gears, very light-weight. Later after I broke a couple chains I decided micro-drive was a bad idea for people my size. Strong enough for my wife but not me. <sigh>

That’s Uniglide to you, Mister!
Not to pile on, but that’s a Dura-Ace Uniglide cassette hub. The cogs are removed by unscrewing the top cog using two chain whips.

Yes, it’s a cassette
You guys are correct, thanks for the help. I’m a Campagnolo expert, made that decision years ago, but happened on this old Dura Ace equipped bike and couldn’t resist. I just assumed a 1984-ish bike would be a freewheel.

Those cassettes are really cool. With a little modification any Shimano cog will fit on the hub. I do custom cassettes on that style of hub all the time. My touring bike has a 7 speed with hand picked ratios specifically built on a uniglide 600 hub. Cool score.

OP, just be certain to save the smallest 13T sprocket which threads to the freehub. It with modified HG cassette sprockets make a great shifting drive train.
