I've disassembled, cleaned and re-lubed lots of ratchets, including the Williams. When it comes to these kinds of round heads with the drop-in cores that house the pawls, parts don't fly when you're just removing the core. All the trouble with losing parts comes from trying to take the cores apart. But honestly, I have yet to find one where disassembling the core was necessary. As long as there's no broken core parts--and with one of these old Williams, if you do have broken core parts, you're done anyway--all you need to do is remove the core and soak it thoroughly with WD-40, which is an effective solvent and will soften any gunk. Then spray it really well with Gum-out parts cleaner. Clean the inside of the head and other parts the same way. Soaking the parts in some kind of lubricant like oil or ATF is not going to cut grease like these two solvents.I have the 1/4, 3/8, 1/2 and a long handle 1/2. I bought them new, a long time ago. They click kind of loud and probably need some lube but operate smoothly. This tutorial confirms what I have heard before and I dread the thought of opening them. There are no spare parts, from what I hear. Parts often go to a parallel universe when I take things apart. I guess I could soak it in oil but I am not sure it is an improvement or necessary. I wonder what Williams lubed them with. If I had it apart I would use Super Lube too. Isn't that what Snap On recomnends for their ratchets?

Once dry, I lightly oil the critical core junctions. I typically use Abu Garcia Silicote Reel Oil in one of those needle oilers. If you want super-slick, try G96 gunsmith oil--this stuff is amazing and crazy slick, but pricier. Be sure to work the oil down into the spring channel. Don't use so much that it's dripping off the core when you're done.
To grease the teeth, I use Abu Garcia Silicote Reel Lube on the 1/4" drives or on really fine tooth ratchets. These lubes are designed to protect small gears and other parts through tens of thousands of cycles beyond what you'll ever put on a ratchet. For the 1/2 drives or coarse tooth I do use the Super Lube. This will do the job superbly without unnecessarily risking parts entry into other dimensions by trying to take the core apart.
That's my method.
