My 7" x 12" horizontal band saw started squeaking a few weeks ago.
I removed the belt and turned it on to determine it was the motor bearings.
The local electric motor fixer company wanted $150 to replace the bearings.
I don't know that something else might have been damaged so I determined to get a replacement motor.
After some Google shopping I found a 2hp motor at Harbor Freight for $165. It replaces the 1.5hp motor the saw came with.
The alternative was to spend near $400 everywhere else.
Nothing I found was an exact match.
The new motor has a 7/8" shaft. The pulleys on the band saw have a 3/4" bore.
So, I bored out the motor pulley to 7/8".
After boring, I had to broach the keyway some.
I purchased a broach set about 12 years ago. This is the first time I've used it.
Unfortunately, the shaft on the new motor is about one pully shorter than on the original motor.
I think I can live with it. I'll just lose one speed setting.
I managed to align the pulleys and still have purchase on the key with the set screw.
Wiring the motor was a bit problematic. The wiring diagram was confusing, mentioning lugs, but there weren't any.
It was just wires that had to be coupled. I eventually figured it out.
Here it is, all hooked up and it seems to be working ok.
