Its from late 1940s I think. Maybe early 50s. Original motor or at least it looks bit art deco like the drill press. Well being just an old Rip Van Winkle man asleep for last twenty years, I was shocked that a new 1/3hp universal motor is now $150. I am sorry, but when did price triple in in the last ten years??? No inflation, my Aunt Annie's fanny!!!!
Not many farm auctions in my area anymore and most washers/driers are scrapped almost immediately. Silly people worry about scrap metal prices to buy bit of beer, and forget there are salvagable parts.
So look on ebay and find a brand new 1/3hp motor for $40 shipped (not stupid enough to buy a used motor that I cant plug in before buying), right shaft and continuous duty, but no base, its for some kind of condenser fan and is meant to mount on its end. Plugged it in when I got it, runs like a new motor should. I salvaged base off a junk motor from my scrap pile, and make a heavy duty steel strap type clamp to hold them together which I welded to the base.
Fine, now the pot metal step pulley. I get the set screws out and soak it in ATF. Nothing even with few light taps. These pulleys are delicate so you cant hammer on them. And the pulley is right down against the cast iron end cap, so no getting any puller under it. And any puller would have to be pulling against the center of the pulley. The outer portions of pulley would just break off or deform if you pulled against them.
So off comes the end cap of the old motor opposite to the pulley. I then put motor on the hydraulic press. Moans and groans and.... yep the other cast iron end cap cracks and breaks apart under the pulley. That shaft and pulley are really welded together with corrosion. Fine, pull it out and cut off end of shaft on chop saw and back on the press. More moans and groans and something gives, yeppers the piece of shaft finally pushed out of the pulley. And miracle of miracles the pulley is still in good shape. Was afraid I would just have a pile of scrap. No old motor, no usable pulley.
Its a shame, the inside of the old motor looks like it could been rebuilt without too much effort by shop that rebuilds motors. But imagine parts maybe not available anymore and probably significantly more than $40 at todays labor prices for rebuilding it. And I bet the pulley would have had to be sacraficed to get the motor apart. I looked and step pulley like that is now $25 shipped on ebay. Not as clean of a casting either.
New motor doesnt look near as robust as the old motor, but probably last me as long as I need a drill press. If not then I will find another motor when time comes. Pretty sure this new motor was never designed to be rebuilt. Its a modern toss and replace item.
Finish up tomorrow. Gotta clean out the pulley hole, lot corrosion in there. Then mount the new motor. Need to rig up a new switch. But can just plug it in when needed for now. The old OEM Delta motor had switch built into it.
