Cincinnati mill 1d

[Fred j f]

I am attempting to fabricate a power feed for the knee to raise and lower the table on Cincinatti 1d milling machine. I have removed the crank and the tapered pin on the clutch-elevating crank. From the exploded view it appears to be threaded on. I really do not want to break any parts. Any ideas for removing the castle nut? I have attached a photo. Thanks, fyf4267

It appears the "clutch" is both taper pinned (dark round hole where set screw was?) and a nice fit on the shaft extending out towards us.
Why do you think the "clutch" is threaded on?

Here is a similar "crank" assy - and its "clutch" is part of the crank assy

Your "clutch" is the "other half" and turns that shaft going into the machine

You would do better asking this in the Old American Iron or Cincinnati forum

Here is a picture from manual and it appears that the bearing 73b slides on shaft 72b. Then 77b threads on to the shaft. Thanks for your help, Fred
