Topic tags/keywords: bandsaw

I was given this Craftsman saw sans motor. I believe the motor part # is 3BS00401. Sears has discontinued this part. Its a 1HP 110 volt motor. I’ve had no luck locating one. Can anybody help? I would like to include a few pictures of the saw and motor location but I’m having no luck with the photobucket, I guess this is how to attach picture files. Photobucket is telling me there are too many “redirects”, whatever that means.

Post a picture directly… Photobucket is a PITA. You may need to resize first (800×600 works well).

Edit-

Judging from the parts diagram, it looks like you could use a pretty standard motor, but it has an unusual mounting plate to attach to the saw. You might be able to find a direct replacement by searching e-bay or even finding another saw that is damaged or otherwise broken but with a good motor to use a parts machine. Short of that, some creative mounting/fabrication would probably get it up and running, but it kind of depends on your skills and what you have available. There are some other manufacturers saws that have a motor mounted similar to that, but I really don’t know if they may be compatible or not.

Cheers,
Brad

You’re probably going to have to just get a different motor and figure out how to belt drive it. If you remove that little cap on the back does the wheel shaft stick out so you can put a pulley on it? You could cut a hole in that base and put a shelf below to set the motor on or just set it behind the unit and you may have to shim it up into position. You’ll have to look in the manual and it will tell you what size pulleys to use.

Well, that was less than helpful. I fail to understand why some just have to make negative comments, other than to just piss people off and alienate themselves in the process.

As for the motor, I’m with dhazelton – it might be a bit difficult to find a direct replacement motor, although one may show up on e-bay or a parts machine may turn up. That saw was made by Rexon, so you may want to do a little searching for them as well.

Short of that, with a little creativity, I’m sure something could be fabricated up to get it operational. A mount could be made (wood would work) to set the motor on so it’s shaft extends into the base similar to what would be there with the stock motor. As for determining pulley size, you would need to measure the driven pulley on the machine first, and then use it along with the replacement motors RPM (typically 1725) and wheel size to calculate the pulley required. For a 14” saw, a SFPM of 3000 or less is recommended, so something in the 2000-3000 sfpm range would probably be sufficient (or you can try to find what the machine originally ran at and shoot for that). You can use the calculator over at the VintageMachinery site to punch in different sizes and figure out the resulting SFPM.

Added – One other option that might be a consideration is to get a treadmill motor. They turn up from time to time for free or very, very cheap. They are usually in the 2-2.5hp range and are variable speed (DC permanent magnet motors). The are great for stuff like band saws and lathes where the variable speed adds a lot of functionality. Might be something else to think about.

Cheers,
Brad

I had a similar problem with a Porter Cable band saw I purchased off Craigslist. The mount for the motor on the Craftsman is the same mount for the Porter Cable motor. It is part of the motor. In my case I had the bad motor. I purchased a replacement motor from Grizzly and swapped end plates and it bolted on perfectly. Since you don’t have the old motor be prepared for sticker shock. The replacement Porter Cable motor was over $400.00. I was never able to find one on E-bay or anywhere else I searched on the interwebs. Maybe your luck will be better than mine!
