How Do I Remove Old Zeus Crankset?
Picked up a '72 Raleigh Competition at an estate sale. Mostly Zeus . I'm guessing I'm going to have to grind down a socket? 16mm?
Any other ideas?

How's it different than other cranks ?
I use an old Park wrench with 14, 15, 16 mm sizes for crank bolts.

High-end sockets from e.g. Snap-On, old USA-made Craftsman, etc. tend to be thinner than inexpensive sockets and will fit in the arm. 16mm "peanut-butter" wrenches from Zeus and Park were also available BITD and turn up on eBay (but the 14-15-16 Park crank wrench does not fit the Zeus arm). Otherwise, yeah, you'll need to grind down a socket to fit.

Zeus uses a 16mm bolt in a 22mm extractor hole. This leaves minimal clearance for a socket to fit in the hole. Stronglight also used a 16mm bolt, but their extractor hole was 23.35mm wide.
While the 16mm socket on the Park 14-15-16mm wrench fits into a Stronglight am, it is too thick to fit into the Zeus arm. Park did make a 16mm thin-wall peanut-butter wrench to fit Zeus cranks (the CCW-16).

16mm 12 Point sockets
12 point sockets usually have thinner walls than 6 point sockets. As John mentioned above older Craftsman sockets had thin walls. 3/8" drive sockets are usually thinner than 1/2" drive sockets.
There are several Craftsman 16mm 12 Point 3/8" Drive Sockets #44311 listed on eBay for ~$4.00 plus free shipping.

...the one time, on the one bike I had to do this, it turned out to be easier (because I have a bench grinder) to just take an odd 16 mm socket and thin the wall. i still have it in the tool box somewhere, and will probably never use it again, because of course when you reassemble the thing, you want to use a crank bolt with a smaller, 15mm head. Or one of those socket headed ones that precludes the need for a dust cap.

I found that a surplus 5/8" socket was perfectly sized for a 16mm bolt head, so I spun it against my grinder wheel until it fit into the threaded crankarm bore.

Thanks all. I found a beat out 16mm 12-pt. socket and ground it down. It did the trick to pull the bolts. A Park CCP-22 pulled off the arms. My Campy puller and and an off-brand puller wouldn't fit the Zeus threads.
Were there dust caps that went with this set or was the bolt designed with the wide top to preclude the use of a dust cap?

The Zeus Gran Sport, Competition, Criterium & early 2000 model chainsets came without a dustcap. Their fixing bolts are chrome plated.
Some of the later model Zeus chainsets did come with dustcaps.

The Zeus extractor thread is standard 22mm x 1mm, so the Park crank puller works fine for that part of the job. But the mounting bolts are 16mm, rather than the more typical 15 or 14mm, and need a thin-wall socket for removal. Many people simply replaced the 16mm Zeus bolts with 15 or 14mm bolts to simplify removal with more common tools.
