Can someone help me identify a Delta 3/4hp motor? I’ve searched informoration found here

You can see from the photo it appears as though the alphanumeric number starts with LP or LR. However, according the site above, those were not used. Is it possible it’s LF? I don’t see it on the list though. Can anyone help me identify this motor? It came with the craftsman 103.20620 jointer I purchased awhile ago but am just getting around to possibly restore.

I suspect that was a replacement motor for the original which would have said Craftsman on it. You primarily need the horsepower and rpm info to find a replacement.
A Lumberjock member named jboehle posted a blog in 2011 of this model including pictures of the motors label with Craftsman part number…113.12190

If you google “Craftsman 103.20620” you will find lots of leads on this machine including pictures.

Not sure why you would need the # in order to do a restore, and it certainly isn’t original to a Craftsman machine – but anyway, it’s a catalog #62-250 motor from the early 50’s. According to the catalog, it’s a 3/4hp 3450 rpm single phase, dual-voltage capacitor start motor with a 5/8” shaft.

Cheers,
Brad

PS: You would not find the model number on the VM link you pointed to, as those are serial numbers.

I suppose I was trying to gather all the information I could about the jointer and motor for a fuller understand of what I have. If the motor needs rebuilding, I’d like to know it’s worth it if it is.
I had assumed it was a replacement motor and didn’t come stock with the joint, it being a delta. According to the thread jboehle started back in 2011, he documented photos of the what I assume to be the stock craftsman motor. Those photos show a 3/4hp, 3,450 motor, same as what my Delta reads. The difference bing my draws a little less in amprage.

Back in the day, they sold the machines without motors or stands, which were optional items. If you had a motor already, no need to buy one for a new machine. If you did need a motor (or stand), then you just picked out which one you wanted and bought it separately. Other than the shaft size (which you could of measured), and the shipping weight (38lbs), all the info above can be gleaned from the motors data plate. The only ‘rebuilding’ the motor should need is new bearings, which will set you back about $10.

You can look up your jointer in the appropriate catalog to see what motor was recommended, and if they did have a ‘package’ deal that included one.

Cheers,
Brad

“I’d like to know it’s worth it if it is.”

That’s up to you. If you can take a motor apart and replace bearings and add a new grounded cord then it’s certainly worth it. Have you tried to run it yet?

Have your say...
