Removing the crank shaft on a C&P NS 10x15

I’ve finally (read it in all caps like this, actually: FINALLY) found a workspace to start fixing up our press, but in order to get it through the door, we’re going to be removing the crank shaft with the flywheel still attached. Our press has the treadle-ready crank shaft with the dip in it, and I’ve already found the plate to remove on the flywheel side of the press so that the shaft will slide right out:

My question is this: there’s a bolt attached to the dip in the crank shaft, and I’m guessing I have to remove that, too, right?

After that, is there anything else I should be disconnecting? I’ve already taken off the wheel on the opposite side of the flywheel.

You may find that there are actually two of those bolts as the part you show is a half shell type fitting therefore when removed will look like a c spanner and seperately a half moon .I can suggest no more as i have no dealings with these machines .

Yes, you will have to completely disconnect the treadle hook (in your case a connection). You will also have to take off the small drive gear on the side with the bull gear in addition to the pulley wheel which you said was already removed. The small gear has a pin which has to be removed and has been discussed many times on this forum.

Thanks, Mike. I’ll do a search for that and bookmark it for reference when we get back to the garage this week!

that bronze/brass casting is a 2 piece set up. one bolt on each side (front and back) it looks to me that this is for an air/vacuum pump run off the crank. this is usually associated with an a kluge auto feeder set up. they powered this press with an electric motor. mark ALL gears with timing marks! in pulling the crank you will be pulling the pinion from gear side. you will lose the timing.(if this is an autofed press)

Yes, there is currently a Kluge Automatic Feeder attached. We’ll be removing it, too. I don’t know if I’ll ever use it, to be honest. The press was indeed powered by a motor, but I will be attaching a treadle and powering it by foot instead.

Is there anywhere I can find a reference for “timing marks?”

Put your own on then you will have perfect understanding on re assembly .(timing marks )

position the press in a definite position, IE completely open or closed. using a center punch and hammer make marks on gear teeth and mating gaps where all gears mesh. this will allow you to reassemble any time in the future. the drawing is basic but do this to all gears involved. 3 dots would be for the next timing point and so on. the “mesh point” from the cam gear to the pinion may not be easily accessible, so mark the cam gear tooth to a spot on the frame or someplace easy to see.
