First of all your 66 must have a boss for a motor or handcranks. If it truly is a 49 it will probably have one.

if it is not a spoked handwheel you will need one of those.

The handcrank will attach with a screw and washer to a tongue and groove slot with a hole through it.

Some handwheels have different depths on the center hubs, so that can be an issue..

Handwheel would normally be in place, but this (above) shows the grove on the handcrank base.

thank you Leon. It has a solid wheel and was originally wired so I have the right attachment placement.

I find the hunt for stuff more fun than having in hand. Maybe I'll splash out for true Singer parts...

Sew Classic and Cindy Peters both sell the hand wheels and cranks.

Since you will be replacing the hand wheel: be careful when you try to loosen the set screw on the clutch knob. Make sure the screwdriver fits well. Then you can unscrew the clutch knob. Make sure you keep track of which direction the three eared lock washer pieces faces. If you get the thing facing the wrong way between the clutch knob and the hand wheel it will dive you crazy. I wish I could tell you which way it is, but that has slipped my mind.

I just did this conversion. The lock washer had three tabs on the outer edge that bend away from the machine when installed properly. Then the shiny stop motion knob screw will hang up on one of the tabs to stop the needle movement when it is unscrewed. I followed the tutorial on a vintage sewing machine blog to get it together so the needle bar doesn't move when I unscrew the stop motion knob. My Franken66 is a combination of parts from a 66-13 that came in a cabinet ($10 from local CL), the spoked handwheel, bobbin winder and faceplate from a Red eye 66 with bad decals ($12 from local GW), and an earlier version of the Chinese handcranks that has metal gears and no decals ($20 on ebay). It sews very nicely, and the handcrank operates smoothly, but I haven't been able to find replacements for the broken hinges on the case, so it has a tendency to fall into the case. I guess I will make a new base for it as the cover won't fit the base with hand crank on it anyway.[ATTACH=CONFIG]593095[/ATTACH]

thank you for the additional info, everyone!

with encouragement from here I turned a little Belaire Bantam into a hand crank to take with me camping/fishing but I mostly found the wind and little patchwork pieces are not a match made in heaven, so I gifted it to a special cousin last weekend.
But I do love hand cranking, hence the 66 idea In a windless window view!

edited to add: this treadle desk and machine were a gift from Dick Wrightman, the founder of treadleon, and I treasure it highly.

Treadleon is a fun site. I bet the Bantam was super sweet.
