Craftsman Motor 266.23450

[RHJO51]

I have this Craftsman 1/2 HP motor I'm putting on a Craftsman DP I'm working on. It's a mod 266.23450 code 5613. Says it's variable speed, reversible. I also have the optional remote control. Seems like a nice fit for my vintage DP. Bearings seem OK but has anyone every cracked one of these open? How difficult is it to get to the bearings? I'd like to change the cord too - it's pretty short. Was also wondering about the age. Is the code 5613 - is this Jan 3, 1956? Thanks for any help and insight you can provide. - Jim

Is the code 5613 - is this Jan 3, 1956?

The Crowntop logo wasn't in use in 1956. That would have had the Heritage logo.
I'd be inclined to believe that the motor was from the 70's. But have no proof.

Here's a GJ thread about that motor:

"grabbed the 1969 catalog while you were adding the image. There it was, both in the motor section as well as being featured with the drill presses."

Thanks for the info and link, helpful. I'm guessing that since these are pretty rare no one here have opened one of these up to do any kind of repair

I think the internals in that motor are DC and probably has permanent magnets along with brushes and a wound rotor.

Thanks Dagny. I'm not a electric motor guy. Does that mean there are no bearings like I'd find in a AC electric motor?

I have a non-working, earlier version of the Craftsman variable speed motor. Mine was made by Emerson Electric. The post below and a few following may give you some insight on its construction.

My motor has bearings and brushes.

The lighter gray portion of yours houses the controls. Underneath the dial plate should be a circuit board. The darker gray portion is the actual motor.

I would remove the screws on the side and gently separate the halves. Based on the older motor, you should have access to the cord connections.

I could not find the manufacturer for code 266.

I have two of those motors, have never opened up either. I have a non-reversible one on my Craftsman 150 floor model drill press and love it. One caution, when running at reduced RPM you MUST give it a cooling period, it's not full duty cycle a low RPM's.

Thank you Frank and Bluebolt, the info you provided is helpful. Frank, the link to the post pics was very helpful, I was curious what the guts of this motor looked like. The motor runs fine but is a little noisy but not clear if it's a bearing or what. I saw a pub for this motor on Vintage Machinery which had some good info on speeds and pulley use. It also said "NOISE - These motors are built with bruch materials that are especially hard to give long brush life. Initially these brushes are noisy during the run in period (10 hours). Once the brushes are seated the noise should be eliminated". So who knows, maybe this motor doesn't have a lot of hours on it and the brushes are still seating.... Thanks again. - Jim

You are welcome. Below are the innards of my motor. Again, this is a different manufacturer and model than yours, but the gist should be the same or similar. Click each for a larger image in a new tab.
