Sears 12" bandsaw motor pulleys out of alignment.

Hi,

anyone have one of these bandsaws?

I found one by the side of the road. I put it together and it has
worked fine for a while. Except for the fact that the belt keeps
falling off of the motor pulley.

It looks like the motor pulley and the pulley attached to the lower
wheel are not in alignment. To put them into alignment both pulleys
have to move so that they are half off their shafts.

Is this the way they are supposed to be? I can't seem to think of any
other way to put the two pulleys in the same plane.

Thanks

Alex

Hi,

I've moved both pulleys as close as possible to the end of their
shafts. They are need to move about 1/2" - 3/4" before they are co
planer. I can't move the motor any closer unless there is some way to
exchange the cover of the motor to make it flatter.

The only thing I can think of doing right now is buying a 5/8" shaft
and making it 1" longer and replacing the existing shaft with that one.

Hi,

I'll find a digitial and post a picture.

Both pulleys are on right. If I flip the directions then they have to
move further apart from each other so that the set screw has something
to latch on.

Is one pulley on backwards?
Or both?

is it possible that the motor has been disassembled and then reassembled
wrong? Are you certain you have the motor mounted corrrectly? What about
moving either the saw or motor? What is the model number?

I had one of those. Try moving the motor to align the pulleys.

I can't picture this. Maybe you could take a photo of your saw and post it
to alt.binaries.pictures.woodworking?

I've also got a (1960's vintage) 12" Craftsman BS. The motor is mounted
below the body of the saw with the shaft pointing towards the back, in the
same direction as the shaft from the lower (driving) wheel. I don't see
how moving *both* pulleys to the ends of their shafts could possibly change
the relative alignment. Maybe your saw has the motor mounted differently
than mine?
